Anton Khirnov	cea71b2139	fftools/ffmpeg: stop using fake dts for generating timestamps When no packet dts values are available from the container, video decoding code will currently use its own guessed values, which will then be propagated to pkt_dts on decoded frames and used as pts in certain cases. This is inaccurate, fragile, and unnecessarily convoluted. Simply removing this allows the extrapolation code introduced in the previous commit to do a better job. Changes the results of numerous h264 and hevc FATE tests, where no spurious timestamp gaps are generated anymore. Several tests no longer need -vsync passthrough.	2 years ago
Anton Khirnov	ba4b73c977	lavf/rawdec: set avg_frame_rate Timestamps in two FATE H.264 conformance tests now start at 1 instead of 0, which also happens in some other H.264 tests before this commit and so is not a big issue. Conversely, timestamps in some HEVC conformance tests start from a smaller value now. Ideally this should be addressed later in a more general way. h264-conformance-frext-frext2_panasonic_b no longer requires -vsync passthrough.	2 years ago

Anton Khirnov	74b961db77	avconv: replace -vsync cfr code with the fps filter. Invented timestamps for the h264 tests return to something resembling sanity. In the idroq-video-encode test when converting 25 fps -> 30 fps the fifth frame gets duplicated instead of the sixth.	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
Måns Rullgård	2fad097788	Add FATE tests This adds a "fate" make target which runs the full FATE test suite. Individual tests can be run with "make fate-$testname". The location of the FATE test samples must be specified with the --samples=PATH option to configure. The tests/fate-update.sh script regenerates the references files and test list from the online FATE database. These are checked in since generating them requires non-standard tools.
