Comment (by dr_pardee):
Hi, thanks for response. Yes, there are audio tracks but not applicable to
my issue in this case (op-atom mxf files).
Here are commands you can use (unzip, cut & paste):
Non-spanned clip (works):
ffmpeg -c:v:0 prores -r 23.98 -i A00006V01.D43559BB_58100BA9.mxf -b:v 800k
-maxrate 800k -s 320x240 -vcodec copy -y -threads 0 -report
A00006V01-part2.mov
Spanned clip part1 (works):
ffmpeg -c:v:0 prores -r 23.98 -i A00006V01.D43559B9_58100BA7.mxf -b:v 800k
-maxrate 800k -s 320x240 -vcodec copy -y -threads 0 -report
A00006V01-part1.mov
Spanned clip part2 (fails with Output file #0 does not contain any
stream):
ffmpeg -c:v:0 prores -r 23.98 -i A00005V01.D43559B4_58100BA4.mxf -b:v 800k
-maxrate 800k -s 320x240 -vcodec copy -y -threads 0 -report A00005V01.mov
For some reason, even if you explicitly specify the video as prores, the
2nd part of a spanned clip will not get processed.
Thanks again
Eric
