Anton Khirnov	9200514ad8	lavf: replace AVStream.codec with AVStream.codecpar Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.	9 years ago
Michael Niedermayer	42801505cd	tests: Add vsynth2 which uses the new reference.pnm The file is already present in git and by using it we can perform more tests without the need of fate samples Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	ed49b142bb	tests: Rename vsynth2 to vsynth_lena This avoids confusion with a growing number of vsynth tests Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Reinhard Tartler	8895bf7b78	Replace lena.pnm The new reference.pnm is a freely licensed replacement. The photo has been taken by Reinhard Tartler on August 28 2014, and is licensed under the expat license as stated at http://www.jclark.com/xml/copying.txt	10 years ago
Josh Allmann	74bc945805	flvenc: Don't over-count metadata. Over-counting occurs if framerate is not set. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Anton Khirnov	43e7f0797f	flvenc: only write the framerate tag based on avg_frame_rate Do not fall back on the codec timebase, since that can be anything for VFR video.	11 years ago
