These frames would be generated using lavfi. An example command would be: ffmpeg -f lavfi -i "testsrc2=s=640x480" -t 1 -c:v jpeg2000 -f rawvideo parser_trial.rawvideo The parser could be tested by trying to decode parser_trial.rawvideo to framecrc.
To translate this into a test, I thought of using the enc_dec command. However, I am unable to pass lavfi stream as an input as it assumes that a filename is being passed. What is a possible solution for this? Can I fix fate-run.sh so that if the source format is lavfi do not convert the parameter to a path? The documentation for adding a test was slightly underwritten, so I have inferred whatever I can by reading the code. > thx > > [...] > -- > Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB > > Concerning the gods, I have no means of knowing whether they exist or not > or of what sort they may be, because of the obscurity of the subject, and > the brevity of human life -- Protagoras > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe". -- ------------- Gautam | _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
