Here above, you are testing for r210 (FourCC: r210) : http://wiki.multimedia.cx/?title=R210 Yet, I said FFMpeg does handle v210 (FourCC: v210) just fine: http://wiki.multimedia.cx/?title=v210 I never mentioned r210. So, not sure why r210 in in our discussions. We are talking about two seperate things. I'm instead talking about r10k which is (R10k, R10g): http://wiki.multimedia.cx/?title=R10k Based on your most recent testing, FFMpeg seems to handle r210 fine. From my testing, FFMpeg handles v210 fine too. My intention is not to discuss r210 or v210. However, what FFMpeg does not handle, is r10k. It is r10k that FFMpeg has issues with (not r210 or v210). You should re-read my last test runs in my prior email. So the commands I used in my last email post was: //10 Bit RGB 444 r10k lossless original -> to FFV1 (lossless compressed) ffmpeg -i "r10kOriginalFile.avi" -pix_fmt gbrp10le -vcodec ffv1 -coder 1 -c:a copy r10kToFFV.avi -f framemd5 -an r10kToFFV.framemd5 //FFV1 (lossless compressed) -> 10 Bit RGB 444 r10k lossless original ffmpeg -i r10kToFFV.avi -pix_fmt gbrp10le -vcodec r10k -c:a copy FFVTor10k.avi -f framemd5 -an FFVTor10k.framemd5 So again, here my goal with FFMpeg is: 10 Bit RGB 444 r10k lossless original -> FFV1 (lossless compressed) -> 10 Bit RGB 444 r10k lossless original However, I've not been able to get FFMpeg to lossless compress and decompress r10k. This is the problem I am having. Hopefully that helps clarify, Cheers, Jason =) > > Thank you, Carl Eugen > > _______________________________________________ > ffmpeg-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/ffmpeg-user _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
