[mythtv-users] Configuring USB3 HDMI capture device non-HDCP source

Tue Aug 15 05:37:44 UTC 2017

Before you stop reading, apparently my cable provider is not enforcing
HDCP as I can view the video streams with VLC without the need to do
any stripping or anything.

I purchased an "Imillet HDMI Video Capture with USB3.0/2.0 Dongle
1080P 60FPS Drive-Free Capture Card Box for Windows Linux Os X System"
[1] and I'm having a hard time getting MythTV to utilize the device.
It is v4l2 capable and I can use VLC, streamer, etc to capture and
view the video. Since my cable provider has moved to all digital, I
don't have much choice other than set-top boxes and IR blasting since
they can't turn off the copy protection for my HDHomeRun Prime (very
small cable provider).

I had limited success with setting the capture device as an "Analog
capture card", but the video plays at half speed (maybe because it is
capturing at 60 fps?). My audio is not coming through just yet because
I don't think I've passed the audio devices to the LXC container (my
previous MPEG-4 cards didn't need it).

I would have thought that "V4L2 Encoder" would be what I needed and
mythtv-setup shows "Probed info: USB3.0 Capture Video [uvcvideo]"
which is correct. When I try to watch LiveTV from it, I get a
segmentation fault.

Any help getting this working would be appreciated. This is Debian
