</div>From a MythTV perspective, it should be treated as an analog capture<br>
card since it uses the standard V4L2 raw video capture interface. The<br>
fact that the underlying video source is HDMI (e.g. a digital format)<br>
as opposed to an analog video format such as NTSC is incidental.<br>
<br>
That said, MythTV does make some assumptions with regards to the rates<br>
at which the raw video capture interface will deliver video (see my<br>
previous email).<br>
<br>
The user might be able to reconfigure his video output at the cable<br>
box to output at 1080p/30 rather than 1080p/60, at which point it<br>
would likely work (although I wonder if perhaps lipsync will drift<br>
over an extended period of recording).<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I believe the device can output in a few different formats, I'm going to mess with that a bit today. For the analog capture devices, I can't set the recording profile to 1080p, only like 700x580 or something so the device is downscaling. I'll see if I can use v4l2-cfg to set the frame rate. When I do a non-raw capture, it understands that the frame rate is 30 or 60 (depending on what I set in steamer) and VLC reports that and plays it back properly.</div><div dir="auto"><br></div><div dir="auto">I can also try twiddling with the code to see if I can get some additional parameters passed to the device, do you know where this code would be?</div><div dir="auto"><br></div><div dir="auto">Thank you,</div><div dir="auto">Robert</div><div dir="auto"><br><span style="font-family:sans-serif">Sent from a mobile device, please excuse any typos.</span></div></div>
