Added the codec id but getting invalid `cur_dts` when trying to stream
copy from v4l2 to nut. Will try to look into this sometime.

ideally some seperation between frames would be kept
for example each frame in its own file might be the easiest
or maybe just add teh codec id to nut and try to store it in that
with stream copy
if it works it should be possible to playback that nit file

thanks

Would dd'ing /dev/video0 be enough and how can I provide the file? Ftp
`upload.ffmpeg.org` seems down.

[FFmpeg-devel] CPIA

2019-05-19 Thread Michael Niedermayer
Hi

Looking at the CPIA decoder, it seems to contain bugs, i have some fixes
but CPIA being a format from V4L testing is trikier.
Can someone who has the right hardware for CPIA, dump some frames into
a file so people and myself can test this without special hw.
Or am i missing something and this can be tested already on arbitrary
systems ?

Thanks

Its not that you shouldnt use gotos but rather that you should write
readable code and code with gotos often but not always is less readable
