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
Luca Barbato	ce70f28a17	avpacket: Replace av_free_packet with av_packet_unref `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.	9 years ago

Martin Storsjö	4f373a5111	vfwcap: Unbreak building after `c201069fa` These headers can't be included in any arbitrary order. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Diego Biurrun	c201069fac	avdevice: Add missing header for NULL_IF_CONFIG_SMALL Also reshuffle headers into canonical order where appropriate.	10 years ago
Diego Biurrun	ab56fabe62	vfwcap: Add fallback define for HWND_MESSAGE Some obsolete versions of the MinGW32 runtime (<4.0.0) lack the definition.	10 years ago
Diego Biurrun	8bc52dbd9d	vfwcap: Drop fallback VfW defines The defines were added long ago when MinGW still lacked them.	11 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	3b3bbdd3e6	lavf,lavd: replace av_new_stream->avformat_new_stream part I. Trivial replacements with sed are done in this commit: sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'	13 years ago

Diego Biurrun	30b4ee7901	Use explicit struct initializers for AVOutputFormat/AVInputFormat declarations.	13 years ago
Anton Khirnov	c14fe6bc99	lavf,lavd: remove all usage of AVFormatParameters from demuxers. AVFormatParameters are converted into corresponding private options in av_open_input_file/stream() compat wrappers, so accessing them from demuxers is redundant.	14 years ago
Stefano Sabatini	a4bda40544	vfwcap: prefer "framerate_q" over "fps" in vfw_read_header() The variable is used for containing the parsed value of framerate, using a lexically consistent name eases readability/understanding. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Anton Khirnov	367732832f	lavf,lavc: free avoptions in a generic way. It's simpler and less error-prone. Fixes some memleaks along the way.	14 years ago

Diego Elio Pettenò	c6610a216e	Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts.	14 years ago
