What is DVI2PCIe Duo?

DVI2PCIe Duo™ is Epiphan's internal (PCIe) dual-link DVI-I / SDI (3G-SDI, HD-SDI and SD-SDI) video capture card. It captures images and video from single-link and dual-link DVI-I, VGA, and unencrypted HDMIand SDI video sources and digitizes them on your workstation via the motherboard's PCIe bus.

The video capture workstation can record and/or stream the resulting uncompressed diagnostic-quality images and videos. On Windows, both audio and video capture is supported for HDMI and SDIsources. An optional A/V kit can be installed to capture S-Video/composite, analog audio and balanced TRS audio. DVI2PCIe Duo captures full HD at 60 frames per second and captures and streams audio and HD video sources with resolutions up to 2048×2048 when connected to a DVI-I dual link connector.

DVI2PCIe Duo captures video and audio from any dual-link or single link DVI, unencrypted HDMI, or VGA sourceand, at the same time from a 3G-SDI, HD-SDI or SD-SDI source.

Using the included Epiphan Capture Tool, DVI2PCIe Duo captures full 1080p HD at 60 frames per seconds and supports resolutions up to 2560×1600. Note in all cases the SDI video signal is captured in RGB 24-bit color and in the case of YUV 4:2:0 chroma sub-sampling, it is converted to this new color space.

DVI2PCIe Duo User Guide What is DVI2PCIe Duo?

The DVI2PCIe Duo capture card is fully compatible with DirectShow in Windows and Video4Linux in Linux.This means you can use it with a number of different third party applications for capturing, recording and streaming video.

DVI2PCIe Duo on Linux

Epiphan provides drivers and an API for linux, but does not provide a capture application. The video grabber is compatible with Video4Linux, so you can use any Video4Linux application for capture. You can also use the EpiphanLinux SDK to write your own application. For more information see the Epiphan product downloads page for your DVI2PCIe Duo. You'll find the Software Development Tools section which contains C and C++api and a java interface and example.

If your capture workstation uses UEFI Secure Boot, your workstation won't be able to discover DVI2PCIe Duo. You must disable Secure Boot on your Linux workstation.

USB device driver (linux)

The Epiphan USB device driver for linux come as a set of pre-compiled binaries and additional source files that you may need to compile before installing on your computer. (Although called the 'USB device driver' this driver also works with Epiphan's internal PCIe video capture cards, including DVI2PCIe Duo).

To download the drivers for your product, go to www.epiphan.com/support and find the support page for DVI2PCIe Duo. From the Downloads tab, select the Linux download link; the linux download page appears.

Once you've drilled into the version of linux for which you want the drivers, click the file links to download a compressed file with everything you'll need to compile and install the driver. Unzip the file and read the README for further instructions.

The driver works with Video4Linux compatible applications (including gStreamer, VLCand the Video4Linux application), and with the Epiphan API.

Epiphan capture API

The Epiphan capture API receives captured images from the USBdevice driver. To record or stream these images you can use a compatible Video4Linux application(such as VLC or gStreamer) or you can use the API to write your own capture application.

TheAPI is optimized for capturing high resolution images from your DVI2PCIe Duo. It analyzes individual images, performs on-device cropping and handles video mode changes.

See the product support page to download the Software Development kit, which includes the Epiphan capture API.

Sample applications

Epiphan provides some sample applications including a sample capture application, a sample settings application and a sample utility for reading and writing EDIDs. Source for some of the samples (such as the capture application) is included in the SDK.

You can download the samples from the same downloads page as the driver.

DVI2PCIe Duo User Guide Physical attributes

Physical attributes

The DVI2PCIe Duo is a PCIe x4 card that can fit in a 4x, 8x or 16x PCIe slot on the motherboard of the video capture workstation. It features a single DVI-I type and a SDI (BNCtype)connector.

To maintain high performance levels, the DVI2PCIe Duo card requires a minimum of PCIe x4. Consult your motherboard manual to ensure the slot you are using is PCIe x4 or higher.

PCIe card performance is determined by the length of the card and slot (x1, x4, x8 or x16) and the generation of the PCIe card and motherboard slot. The DVI2PCIe Duo card is a generation 2 card and is fully backward compatible with first generation slots. The card will perform at first generation speeds.

b. Select the grabber you wish to configure.

c. Click Edit Configuration; the edit configuration window opens.

DVI2PCIe Duo User Guide DirectShow video adjustments

DirectShow video adjustments

In the Epiphan Capture Tool, the Capture » Configure Device » DirectShow page lets you configure how the device interacts with DirectShow compatible applications. From the resolution to whether or not the image is flipped, there are a variety of options available. See the table below for an explanation of each option.

You can also access this screen using the Epiphan applet in the ControlPanel by selecting the video grabber you'd like to configure and clicking Configure Device or Default Configuration.

The adjustments made here are stored in the device driver and are used until you change them again. Once applied, you do not need to keep the Epiphan Capture Tool open to use the values you set. Be aware that third party DirectShow compatible applications can also have settings that may make it appear your settings are not being honored. If you're having difficulty seeing your changes, check the third party application's advanced settings.

Item Description

Use this checkbox to force the resolution your video grabber reports to DirectShow compatible applications.When checked, the drop down box

Fix resolution

has a list of resolutions from which you pick your desired resolution.

If you choose a resolution that is smaller or larger than the source video, theEpiphan drivers will scale the image for you (unless you uncheck

Limit frame rate to

Normally, when choosing to use a fixed resolution with DirectShow, you'll want the Epiphan drivers to scale the image for you. Use the slider to determine the type of scaling you'd like. Scaling performance is a tradeoff between quality and CPU cycles on the capture computer. Lower quality (left side of the slider) is faster and takes fewer CPU cycles, where higher quality(right side of the slider)is slower and takes more CPU time. Try different values out to find the one that works for your specific use case.

Use this check box to flip your captured image vertically when sending over DirectShow.

Use this to limit (or fix)the frame rate for the data you send to DirectShow.

For example, if you're using a DirectShow-compatible application like WebEx and you're sharing something relatively static(like a PowerPoint presentation), you could limit the frame rate to 5 fps, which would be plenty for people watching at the other end, and would avoid filling your data pipe with identical images.

DVI2PCIe Duo User Guide Visual video adjustments

Visual video adjustments

The Adjustments page lets you configure the device to manage slight shifts in the data and the color mode you're capturing from. If you have a VGAsignal connected, options for configuring VGA-specific tuning parameters are also available.

You can access this screen by selecting Capture » Configure Device » Adjustments or using the Epiphan applet in the ControlPanel by selecting the video grabber you'd like to configure and clicking Configure Device or Default Configuration.

This checkbox allows Wide Aspect Ratio VGA modes to be displayed by

the video capture application window. The Epiphan USB device driver

may not be able to determine whether the video source is sending a wide

video mode signal. You can select this option if your video source uses a

wide video mode to make sure that the Epiphan USB device driver selects

a wide video mode.

Generally your DVI2PCIe Duo auto-detects input type, but in case of an

issue where the input type isn't detected, you can select this checkbox to

capture analog component video with YCrCb encoding.

When capturing from some sources, the video grabber cannot correctly

determine the order to place interlaced lines. Use this checkbox to resolve

the issue.

DVI2PCIe Duo User Guide Set VGAmodes

Set VGAmodes

The VGA Modes page lets you configure the VGAmodes used for analog video capture.

You can access this screen by selecting Capture » Configure Device » VGA Modes or using the Epiphan applet in the ControlPanel by selecting the video grabber you'd like to configure and clicking Configure Device or Default Configuration.

The video grabber supports many common VGAmodes out of the box. If however you wish to capture from a custom VGA source (i.e. custom resolution or timing) you can add that here. You can also uncheck any VGAmodes you'd prefer the video grabber doesn't try to use when tuning the capture parameters for your source.

To add a custom VGAvideo mode:

1. Launch the EpiphanCaptureTool.

2. Select the Capture » Configure Device menu item; the configure dialog appears.

DVI2PCIe Duo User Guide Record a video

Record a video

The Epiphan Capture Tool can record the images captured from your DVI2PCIe Duo as a video.

You can choose to capture audio (see Configure audio) and can also alternatively choose to save individual image files instead of a video, see Record as a series of images.

To record a video of your captured video source:

Step 1: Set the codec

Take this opportunity to select your encoding codec. Codecs are the software that take the uncompressed video frames from the DVI2PCIe Duo and combine/compress these into a digital video file that you can view with a player, share with a colleague or upload to a video sharing site, like YouTube.

By default, your operating system comes with some default codecs installed, no additional codecs come with the Epiphan CaptureTool. You can choose to install third party codecs such as x264. Picking the best codec for your use case is beyond the scope of this document, but you can find many resources (and debates) about this topic on the Internet.

To configure the codec:

1. Connect your video source to the video grabber.

2. Connect the video grabber to a USB port on your capture workstation(use USB 3.0 for best

performance or if you plan to capture embedded audio).

3. Launch the Epiphan CaptureTool using the installed desktop shortcut. See or Epiphan Capture Tool.

4. Select theTools »Options menu item; a dialog box opens.

a. Select the Recording tab.

DVI2PCIe Duo User Guide Step 2: Record

b. Ensure the Record as drop down has Video selected.

c. Use the Select Codec... button to open the VideoCompression dialog. Choose from codecs

installed on your system and click OK to close the Video Compression dialog.

d. If desired, modify the AVI file size limit. Recording will automatically be stopped when this

limit is reached.

e. From this page you can also Configure optional recording settings such as file names and

recording period.

f. Click OK to save your Recording settings.

Step 2: Record

With the Epiphan Capture Tool properly configured, all there is to do is record your video!

DVI2PCIe Duo User Guide Step 2: Record

As images/frames are captured by the video grabber they are recorded to the video file. The status bar displays the name and location of the video file, the elapsed recording time and the number of frames (or images) recorded.

To record your video:

1. The Epiphan Capture Tool should already be capturing and previewing your video source (if you see a

No Signal message, disconnect and reconnect the cables to make sure they are all seated correctly).

2. Optionally, configure audio capture and enable audio capture. See Configure audio.

3. Select Capture »Start Recording, use the red record button or keyboard shortcut Ctrl-R to start

recording; a Save dialog opens.

DVI2PCIe Duo User Guide Step 2: Record

4. Specify the filename and folder to save your file. (See Configure optional recording settings for pre-

configuring recording file names.)

5. When you are done capturing, use the pause or stop buttons to pause or stop recording. (You can also

use the keyboard shortcut Ctrl-U for pause and can use the menu items Capture » Pause or Capture » StopRecording to control recording.)

6. Use your operating system's file browser (Windows Explorer or Finder) to find your saved capture file.

If the status bar is visible, the filename and path of the last saved file is found in the status bar at the bottom of the EpiphanCaptureTool.

If you're having trouble capturing embedded audio, make sure you have the video grabber connected to a USB 3.0 port. Due to the extra volume of data that needs to be captured, embedded audio capture is only supported when connected via USB3.0.

HDMIaudio capture may fail if your device has an old or incorrect EDID loaded. See Update device EDID.

When the video file reaches the AVI file size limit, one of the following occurs based on recording configuration settings:

l recording stops;

l recording continues and a new video file is created; or

l recording continues and the original video file is overwritten.

To set recording options refer to Configure optional recording settings.

DVI2PCIe Duo User Guide Crop the captured image

Crop the captured image

In most video capture situations, you'd like to record everything that is captured by the DVI2PCIe Duo. Sometimes, however, there's a need to remove some information (e.g. confidential or personal information) or to crop out black bars or unwanted areas of a scene. For these purposes, the Epiphan Capture Tool lets you crop the captured source prior to recording.

For example, using cropping you can change your capture from what you see on the left side, below, to the cropped image on the right. The status bar displays the cropped coordinates.

To set capture cropping, start by Record a video

To specify your cropping parameters:

1. From the Tools » Options dialog, select the Capture tab.

2. Check the Enable hardware cropping checkbox.

DVI2PCIe Duo User Guide Crop the captured image

3. In the Width and Height fields, specify in pixels the size of the cropped area that you want to capture.

4. Using the Left and Top fields, specify in pixels the top left corner where to start capturing. As you

change these values, you can see the visible portion of the image change in the cropped area.

5. ClickApply to see the changes immediately and keep fine-tuning, or clickOK to save your changes.

DVI2PCIe Duo User Guide Update device EDID

Update device EDID

Extended display identification data (EDID) is data provided by a video display device (usually a monitor) to describe its capabilities to a video source (usually a graphics or video output card in a PC or another device). The video source uses the EDID to determine the capabilities of the monitor to determine the resolution, color depth and other settings that the monitor can support.

In the case of your DVI2PCIe Duo, it's acting as the monitor for your video source. Epiphan factory-loads your video grabber with a comprehensive EDID that describes all the video modes it can support. When you connect a video source (such as a laptop or video camera), this source interprets your DVI2PCIe Duo as a monitor and uses its EDID to negotiate which video signal to send.

EDID is crucial for DVI sources but mostly ignored by VGA sources.

Generally, the factory loaded EDID correctly emulates a monitor that supports your video source. However sometimes, particularly if your source uses a custom set of display properties, you need to help the video grabber by uploading a custom EDID to force the capture card to report that it emulates a resolution, color depth, etc needed by your laptop, camera or other video source.

For example, you can upload a custom EDID file to your DVI2PCIe Duo that reports that it only operates at 1040x768. When the video source reads the EDID from the video grabber, the video source will reset to operate at 1024x768 as set in the EDID.

In addition to needing to load a specific EDID, you may from time to time,want to upgrade your capture device with the latest factory EDIDfrom Epiphan.

Upload a new EDID

In most circumstances the factory installed default EDID, is sufficient. However, there may be some cases where a video source uses resolutions that you do not want to use. In that case you can choose an EDID that forces the video grabber to use a specific set of attributes.

EDID changes are permanent until you replace them with another EDID.

1. First, download a new EDID file, by going to the Epiphan support web page.

2. Select the support page for DVI2PCIe Duo.

3. Scroll to the EDID section.

4. Click an EDIDfrom the list; the file is saved to your downloads folder on your hard drive.

DVI2PCIe Duo User Guide Upload a newEDID

To return to the factory default EDID, select the "default configuration" EDID from the download list.

5. Connect your video grabber to the capture computer.

6. Disconnect your video source from the video grabber.

7. Launch the Epiphan CaptureTool.

8. Select the Tools » Upload EDID to device... menu option; a file selection dialog opens.

9. From the Open dialog, find the downloaded EDID file and select it.

10. A warning dialog reminds you to disconnect your source. Make sure no source is connected to the

video grabber and click OK.

11. In a few short moments, the EDID upload is complete.

DVI2PCIe Duo User Guide Practical EDID example

Practical EDID example

Here's an example of how a custom EDID can resolve a capture issue.

Let's say you have a flat panel monitor connected as your video output device that has a fixed screen resolution of 640×480. Then you replace that flat panel monitor with a DVI2PCIe Duo and the source system changes its video output resolution to 720×400.

Why did the resolution of the system change? That's because the video source prefers 720×400. Originally, the video source. was forced to operate at 640×480 because the flat panel monitor didn't support 720×400. But since the DVI2PCIe Duo supports 720×400, the system automatically changed to its preferred resolution.

But what if you want a screen resolution of 640×480 and you can't force the video source to operate at that resolution?,A custom EDIDis what you need. Epiphan creates custom EDIDs for the DVI2PCIe Duo. For example, a custom EDID that excludes support for 720×400 would resolve this situation. Now when you upload the custom EDID to the video grabber, the video source no longer finds support for 720×400 and it returns to operating at 640×480.

DVI2PCIe Duo User Guide Configure display options

In the default configuration, when actively recording a video, it looks like this (RECORDING tag, file location, duration and frame count are added to the status):

DVI2PCIe Duo User Guide Status bar

Video recording complete

When video recording is complete, the status bar updates to show the final file location and duration. This stays int he status bar until the application is closed or recording is restarted.

Recording images

When recording your source as a series of images, the status bar shows the RECORDINGtag and name of the current file.

Recording images complete

When image recording is complete, the status bar indicates the number of image frames that were saved.

Optional information

Other information can be displayed on the status bar, depending on the the configuration items set in the Tools » Options »Display menu. They are shown (mostly) separately below, but you can turn any number of these optional status bar items on at the same time - you may simply need to make sure your capture window is wide enough to see all the data!

l The current capture frame rate.

l The crop rectangle showing the top left corner(0,0 in the example), the bottom right corner and the

resulting frame size.

l Audio encoding information.

DVI2PCIe Duo User Guide Pause video capture

l The number of frames or images the video grabber has captured since the application started.

Pause video capture

You can use the pause button on the toolbar, access pause from the capture menu or use the keyboard shortcut Ctrl-U to pause capture. When you pause capture, the following things happen:

l The last captured frame remains open in the Epiphan Capture Tool(no new frames are grabbed). This

image can be saved, copied or printed. See Copy, save, or print a snapshot.

l If you are recording video:

l Your current video recording (if applicable) is closed.

l If Automatically restart capture (from the Tools » Options dialog) is unchecked, video capture is

stopped and the video file finalized.

l If Automatically restart capture is checked, pressing pause again or selecting Capture»Resume

Capture will unpause and will either overwrite the existing video file or start a new one, depending on the configuration you set. See Configure optional recording settings.

l If you are recording images:

l No further images(if applicable) are saved.

l When you press pause again, image capture starts again immediately

Pausing capture is particularly useful when you're also streaming live - this way you can prepare something different or type in a password without having sensitive information captured.

Record as a series of images

There are two ways you can record using the Epiphan capture tool and your DVI2PCIe Duo: capturing individual images or capturing video. To learn how to capture video, see Record a video.

It is not possible to capture audio when recording your source as a series of images.

To capture your video source as a series of images:

Step 1: Set the capture mode, file format and capture frequency

By default, the Epiphan Capture Tool captures in video format, so it's important to change the mode before starting your recording.

DVI2PCIe Duo User Guide Record as a series of images

To configure the image capture mode and file format:

1. Connect your video source to the video grabber.

2. Connect the video grabber to a USB port on your capture workstation(use USB 3.0 for best

performance).

3. Launch the Epiphan CaptureTool.

4. Select theTools »Options menu item; a dialog box opens.

5. Select the Recording tab.

6. Ensure the Record as drop down has Images selected.

7. Use the Format drop down to select from BMP, PNG or JPEG(JPG).

8. In the Save options section:

DVI2PCIe Duo User Guide Record as a series of images

a. Specify a folder for saving the files. If you don't specify a folder, your images will be saved in the

same folder as the Epiphan Capture Tool.

b. If desired, specify a custom Prefix for each file.

c. Use the Suffix drop down to determine whether you're using decimal (d) or hexidecimal (X)

characters for the suffix, and the number of leading zeros in the filename (e.g. %04d means a decimal suffix with 4 digits, the first few will have three leading zeros (cap_0001.bmp)).

d. Set the Start value to the first number you want to use in your file name.

e. Use the Example section to see the result of your file name edits.

f. Check the Overwite existing files checkbox if you want new images to overwrite old ones.

g. Check the Ignore write failures checkbox if you want to proceed regardless of whether or not

the images are still being saved. (e.g. with this box checked, you will not be warned when you run out of disk space or if there is a permissions issue preventing file writing).

9. Determine how often you want to save images. Saving all frames will save up to 30 images per second,

which can quickly take a lot of space on your hard drive!

10. Select Save all frames to save each frame as an image.

11. Select Skip and set a value to save an image every X frames (e.g. set Skip to 10 and you'll save an image

every 10 frames).

12. Select Wait and set a time intervale between image saves.Use this to collect a frame every few seconds

or minutes (choose from milliseconds, seconds, minutes and hours).

13. Lastly, decide if you want to save only a certain number of images or if you want to continue saving

images until request the application to stop recording.

14. To use the record button/control to stop saving images, leave Automatically turn recording off

unchecked; otherwise, check the checkbox and specify your limit in frames or seconds.

15. Click OK to save your Recording settings.

DVI2PCIe Duo User Guide Record as a series of images

Step 2: Record

With the Epiphan Capture Tool properly configured, all there is to do is record your series of images!

As images/frames are captured by the video grabber they are saved as individual image files. While capturing, the status bar displays the name and location of the last saved image. The total number of images saved is displayed when recording stops.

To record your images:

1. The Epiphan Capture Tool should already be capturing and previewing your video source. If you see a

No Signal message, disconnect and reconnect the cables to make sure they are all seated correctly.

2. Select Capture »Start Recording, use the red record button or keyboard shortcut Ctrl-R to start

recording; the Save dialog opens.

3. When you are done capturing, use the pause or stop buttons to pause or stop recording. You can also

use the keyboard shortcut Ctrl-U for pause and can use the menu items Capture » Pause or Capture » StopRecording to control recording.

4. Optionally, choose a starting digit for your sequence.

5. Optionally, check the Overwrite existing files checkbox if you'd like to automatically overwrite files if

you already have files with the same name.

6. Click OK.

7. Start recording and specify a location and root name for your video files.

8. When recording, use the pause button on the toolbar (keyboard shortcut Ctrl+U or Capture » Pause

) between recordings and click either pause again to restart, automatically creating a new video file with the name in the sequence.

Configure recording period

If desired, you can configure the Epiphan Capture Tool to stop recording after a specified time period has elapsed or a specified number of frames have been saved. For example, if you know you always need a 1 minute video when capturing from an ultrasound.

To overwrite the same file each time you record:

DVI2PCIe Duo User Guide Limitations and Known Issues

Limitations and Known Issues

This section includes known issues or limitations that affect functionality or usability for the current release and offers workarounds these them.

l DVI2PCIe Duo's 3.5 mm audio port can appear as either the Line In or as MicrophoneIn in your

computer's device manager. Workaround: After reboot, stop any applications using the device before making changes in the control panel. For best results, ensure all applications are using the same input device.

l Opening the video signal in multiple applications at the same time on your video workstation affects

signal performance. For the best performance during live streaming and recording, we recommend that you close any unnecessary applications that access the video signal. For example, if you aren't using the Epiphan Capture Tool for live streaming or to record, close the tool after you finish configuring the video grabber.

l The Epiphan Capture Tool labels VGA input signals that are 1400x1050 @ 60fps as 1680x1050 in the

window title, even though the actual signal is 1400x1050. The input signal is not impacted and you can either disregard the text in the title or add a custom video mode that is 1400x1050 @ 60fps.
