There are only 29 VOP encoded, and over 1900 N_VOP packets. If you just demux the sample file, you will get 1947 packets I used the Xvid decoder from http://svn.xvid.org/trunk/xvidcore/examples/xvid_decraw.c to decode the same file, and their decoder outputted 1947 frames. > > If you need cfr, you can request it. > true, but this works as long as you have 2 frames and you can cfr between them. But what if you have the last X second of the file with only N_VOP frames In this case, the decoder will not output frames and the transcoded file will be shorter by X second > Once the frames are duplicated, you can't undo the file > size multiplication. > > Carl Eugen > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel > _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
