Nekopanda	f4d5d7e8de	avcodec/mpeg2dec: Fix motion vector rounding for chroma components In 16x8 motion compensation, for lower 16x8 region, the input to mpeg_motion() for motion_y was "motion_y + 16", which causes wrong rounding. For 4:2:0, chroma scaling for y is dividing by two and rounding toward zero. When motion_y < 0 and motion_y + 16 > 0, the rounding direction of "motion_y" and "motion_y + 16" is different and rounding "motion_y + 16" would be incorrect. We should input "motion_y" as is to round correctly. I add "is_16x8" flag to do that. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago

Anton Khirnov	832ba44d8d	avconv: saner output video timebase. r_frame_rate should in theory have something to do with input framerate, but in practice it is often made up from thin air by lavf. So unless we are targeting a constant output framerate, it's better to just use input stream timebase. Brings back dropped frames in nuv and cscd tests introduced in `cd1ad18a65`	13 years ago
Anton Khirnov	cd1ad18a65	rawenc: switch to encode2(). This changes a number of FATE results, since before this commit, the timestamps in all tests using rawenc were made up by lavf. In most cases, the previous timestamps were completely bogus. In some other cases -- raw formats, mostly h264 -- the new timestamps are bogus as well. The only difference is that timestamps invented by the muxer are replaced by timestamps invented by the demuxer. cscd -- avconv sets output codec timebase from r_frame_rate and r_frame_rate is in this case some guessed number 31.42 (377/12), which is not accurate enough to represent all timestamps. This results in some frames having duplicate pts. Therefore, vsync 0 needs to be changed to vsync 2 and avconv drops two frames. A proper fix in the future would be to set output timebase to something saner in avconv. nuv -- previous timestamps for video were wrong AND the cscd comment applies, one frame is dropped. vp8-signbias -- the file contains two frames with identical timestamps, so -vsync 0 needs to be removed/changed to -vsync 2 and avconv drops one frame. vc1-ism -- apparrently either the demuxer lies about timestamps or the file is broken, since dts == pts on all packets, but reordering clearly takes place.	13 years ago
Anton Khirnov	d2afbd9a56	frame{crc/md5}: set the stream timebase from codec timebase. Right now those muxers use the default timebase in all cases(1/90000). This patch avoid unnecessary rescaling and makes the printed timestamps more readable. Also, extend the printed information to include the timebases and packet pts/duration and align the columns. Obviously changes the results of all fate tests which use those two muxers.	13 years ago
Reimar Döffinger	05741d70c7	Fallback to input timestamps for non-delay encoders. Causes FFmpeg to pass through the correct pts values, instead of clobbering all to AV_NOPTS_VALUE (the av_init_packet default) to then make up new ones based on only fps when muxing. Included are also the related FATE ref changes, which all some reasonable on quick investigation. Also set all H.264 references to us -vsync drop to reduce the diff for the ref files. Otherwise almost all H.264 references need to change, mostly due to now starting with negative pts values. About 20 additional H.264 conformance tests needed -vsync drop anyway because they create pts values that are out of order and thus not possible to mux otherwise.

Anton Khirnov	0844b57c11	crcenc: add flags AVFMT_NOTIMESTAMPS for crc, as it ignores the timestamps. AVFMT_VARIABLE_FPS for framecrc, as it prints dts. Many FATE changes, because avconv is no longer duplicating frames in those tests. Also added -vsync 0 for some tests to prevent avconv from dropping frames until it can be fixed more properly.	13 years ago
