I know about Hauppauge 610 Analog Video Capture Script or Command and Script to Capture VHS Tapes Using the Hauppauge 610 USB-Live 2 Analog Video Digitizer and Video Capture Device. I run their scripts and still get my error.
I have been trying to capture video from a Sony XC-ST50 camera using a coax-rca plug into a Hauppauge USB-Live2 on 18.04. I installed the drivers as they describe here. I have tried opening this with OpenCV and ffmpeg with various commands using v4l2 including ffmpeg -f v4l2 -i /dev/video0 -vf format=yuv420p -framerate 25 output.mp4. Each time I get some variation on this error:
[video4linux2,v4l2 @ 0x561552c8d820] ioctl(VIDIOC_QBUF): Message too long
/dev/video0: Message too long
