Question / Help Hauppauge WinTV PVR-150 and Ubuntu 16.04

[retanicus]

Hello all,

First off, I would like to say that OBS is amazing. To every developer out there who works on OBS, you're awesome! This is such a wonderful piece of software, I've been using it to stream on Linux and Windows for about a month now and love it.

Anyway - I have a WinTV-PVR-150 from Hauppauge. I notice that OBS cannot initialize the video stream for this capture card, but it works just fine in VLC /dev/video32 with output 2 enabled (for composite).

here's a section from dmesg initializing the PCI card:

Is there any way I can manually modify an OBS config and send my own v4l2 command? I really like using this analog capture card.
Oh, and I am also using the 32-bit version of OBS if that makes any difference (It's running on a Pentium 4 HT - older setup but works with the streaming and capture card)

I'm not sure to file this as a bug or more of help for now. Did I skip anything? Do I need any additional libraries to make OBS recognize this card?

Here is some more information...

v4l2-ctl --list-devices
Hauppauge WinTV PVR-150 (PCI:0000:02:09.0)
    /dev/video0
    /dev/video24
    /dev/video32
    /dev/vbi0
   
v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
    Index        : 0
    Type        : Video Capture
    Pixel Format: 'MPEG' (compressed)
    Name        : MPEG-1/2/4

I also just realized there's a sticky thread regarding v4l2 devices in Linux, so I apologize that I did not post in that sticky, but I would be happy to add to that sticky with a solution once a solution is found here.

Hi! Just found one of this cards in my stock, can you share the exact config or command line you use to start the vlc stream?
