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
Anton Khirnov	dc6527ed90	nutenc: do not use AVCodecContext.frame_size It will in general not be available. Use block_align if known or fall back to av_get_audio_frame_duration().	9 years ago
Luca Barbato	1e7ff5ac69	nut: Use the correct codec_tag when multiple are available Some codecs use the codec_tag to signal specific information and picking the first one would lead to a broken file. Bug-Id: 883 CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Martin Storsjö	8e32b1f096	libavformat: Use ffio_free_dyn_buf where applicable Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Anton Khirnov	80a11de7dc	nutenc: do not use has_b_frames It is unreliable, especially when the stream codec context is not the encoding context. Use the codec descriptor properties instead.	10 years ago
Vittorio Giovara	b69183f65d	nutenc: check for negative index rather than assert CC: libav-stable@libav.org Bug-Id: CID 703721	10 years ago
Anton Khirnov	d754ed4172	riffenc: take an AVStream instead of an AVCodecContext It will be useful in the following commits. Also, rename the AVCodecContext pointer name from 'stream' to 'codec'.	11 years ago
Luca Barbato	c94e2e85cb	nut: Support experimental NUT 4 features Add the low overhead pipe mode and the extended broadcast mode. Export the options as 'syncponts' since it impacts only that. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Luca Barbato	46c1917350	nut: use a define for the nut version Ease switching version in the future and make evident why that value.	12 years ago

Luca Barbato	21de6ba5c1	nut: export codec_tag provided by rawvideo Raw audio does not provide valid audio tags while rawvideo does. The fate refs have to be updated because it undoes the previous tag change.	12 years ago
Luca Barbato	1bd442c276	nut: prioritize native tags Use native tags instead of avi ones, simplifies a lot raw video codecs handling.	12 years ago

Anton Khirnov	3b4bb19e63	lavf: flush the output AVIOContext in av_write_trailer(). This is consistent with stdio and is what we want to do in all cases. Fixes a bug in the voc muxer which didn't flush in write_trailer() previously. This is the cause of the change in the test results.	12 years ago

Ronald S. Bultje	fd48721849	lavf: use conditional notation for default codec in muxer declarations. This removes the use of macro nesting in these code constructs, which makes it easier to parse in pre-processors.	13 years ago
Martin Storsjö	20234a4bd7	cosmetics: Align muxer/demuxer declarations Also add missing trailing commas, break long codec_tag lines and add spaces in codec_tag declarations. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	c3f9ebf743	lavf: make av_set_pts_info private. It's supposed to be called only from (de)muxers.	13 years ago
Anton Khirnov	82ab61f901	lavc: use avpriv_ prefix for some mpegaudio symbols used in lavf. Specifically, ff_mpa_freq_tab, ff_mpa_bitrate_tab, ff_mpa_decode_header, ff_mpegaudio_decode_header.	13 years ago
Luca Barbato	5ee5dc4e9a	nutenc: add namespace to the api facing functions Rename write_{header,packet,trailer} to nut_write_{header,packet,trailer} in order to make easier debugging them.	14 years ago
Anton Khirnov	dfc2c4d900	lavf: use designated initialisers for all (de)muxers. It's more readable and less prone to breakage.	14 years ago
