Unable to use AVerMedia - BU113 to capture Steam Deck #1467

Your system information

I just got myself the JSAUX RGB Docking Station HB1201S and tried to capture the Steam Decks display to my PC (ArchLinux) using the AVerMedia BU113.

This was all tested in desktop mode, as I've read using a capture card doesn't work in gaming mode. When I did try in gaming mode, the Steam Deck's screen went black until the HDMI cable was taken out. In "Display Configuration" in the "System Settings" I have set the "Device: A/Vaux Electrontics AVT BU113" to "Replica of Built-in-Screen".

To view the capture card on my PC I run this command, changing video0 if needed:

mpv --force-seekable=yes --no-config av://v4l2:/dev/video0 --profile=low-latency --audio-file=av://pulse:alsa_input.usb-AVerMedia_Live_Streamer_CAP_4K_5311437600276-02.analog-stereo

mpv then opens to a black window and a few seconds later says "No Video", obs does the same thing.

I have tried displayport and hdmi, both didn't work. Plugging my phone into the dock captures the screen, as well as my laptop which also run ArchLinux.

Steps for reproducing this issue:

  1. Plug the Steam Deck into the HB1201S.
  2. Connect the HB1201S and BU113 with a HDMI cable.
  3. Connect the BU113 to your PC with a USB-C cable. image
  4. On the PC, run this command, changing video0 if needed: 
    mpv --force-seekable=yes --no-config av://v4l2:/dev/video0 --profile=low-latency --audio-file=av://pulse:alsa_input.usb-AVerMedia_Live_Streamer_CAP_4K_5311437600276-02.analog-stereo
  5. mpv shows a black window for a few seconds then shows "No Video".
  6. You can also check using obs: 6.1. Open obs, and create a scene if one isn't already there. 6.2. Add a "Video Capture Device (V4L2)" source, and make sure the device is set to "Live Streamer CAP 4K: Live Stre...". 6.3. In the preview window for the "Video Capture Device (V4L2)" source, it shows as black for a few seconds then shows "No Video"
