You need to insert something like if(j) s->dup++ here. Otherwise the log becomes wrong, as in the 48fps example: Parsed_fps_0 @ 0x34ea4a0] 24 frames in, 48 frames out; 0 frames dropped, 23 frames duplicated. Anyway, the conversion results are accurate now for any sample I tested. Thanks. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
