[FFmpeg-user] Encode lossless Dirac?

[Peter B.]

Success!

The current git-version of ffmpeg (N-35077-g7876f14) encoded a Dirac
video losslessly, with "libschroedinger" v1.0.9, using the following
command:

[code]
ffmpeg -i input-ffv1.avi -an -vcodec libschroedinger -qscale 0 dirac-0.mkv
[/code]


I've verified that its lossless, using "-f framemd5" and "vimdiff" like
this:
[code]
ffmpeg -i dirac-0.mkv -an -f framemd5 dirac-0-checksums.txt
ffmpeg -i input-ffv1.avi -an -f framemd5 input-ffv1-checksums.txt
vimdiff *-checksums.txt
[/code]


All frames match perfectly with the original.

Thank you very much,
Pb


PS: Now I'm *not* posting the full uncut console output, since I just
wanted to close this thread with the information which commands were
successful. I hope it's fine like that?
