Fazantix was running with internal Hagibis and external Bus 004 Device 016: ID 345f:2130 UltraSemi USB3 Video

After a while, the external capture (which had the camera connected to it) failed. Fazantix showed an orange blob, but did not crash itself.

Fazantix was stopped, and started:

The above was repeated a number of times, same result.

Tried a random ffmpeg command from the internets:

ffmpeg -f v4l2 -framerate 30 -video_size 1280x720 -i /dev/video0 -c:v libx264 -preset ultrafast -tune zerolatency -pix_fmt yuv420p -f mpegts tcp://0.0.0.0:1234?listen=1

Video could be watched by a remote mpv client just fine.

ffmpeg process stopped, fazantix started, and all was well.

Conclusion: ffmpeg does something to the ms203X which revives it. Need to figure out what it is and to the same.

Tried a random ffmpeg command from the internets: ``` ffmpeg -f v4l2 -framerate 30 -video_size 1280x720 -i /dev/video0 -c:v libx264 -preset ultrafast -tune zerolatency -pix_fmt yuv420p -f mpegts tcp://0.0.0.0:1234?listen=1 ```` Video could be watched by a remote mpv client just fine. ffmpeg process stopped, fazantix started, and all was well. Conclusion: ffmpeg does something to the ms203X which revives it. Need to figure out what it is and to the same.

The "bad arguments" error on dequeue buffer is this in the v4l docs:

The buffer type is not supported, or the index is out of bounds, or no buffers have been allocated yet, or the userptr or length are invalid.

When it's in a hung state the metrics show that the requests for all sources keep increasing but the frames_read_total for the capture card stops increasing. There's no other output from fazantix telling something is going wrong except the orange fallback
