Has anyone managed to capture a feed using the "USB Capture SDI 4k"
from Magewell with ffmpeg?
It runs for awhile but then a 0 byte packet comes along and ffmped just stops.
It doesn't quit, but the frame number just stops and it doesn't do
anything after rhis.
I saw 2 bugs from 2014 and both

Hi,
I'm looking for a sample picture with more than 8 bit per plane, e.g. 16
bit per plane preferably with YUV colours.
Is there something like here? : https://samples.ffmpeg.org/image-samples/

Thanks,

it seems ffmpeg had hardcode starting from 1.
you could modify source code file 'libavformat/dashenc.c’ in function
dash_init, member ‘segment_index' of OutputStream.
i’m not sure which unexpected result would be raised up.
