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

Michael Niedermayer	4d0f6d3fb4	avdevice/vfwcap: revert header reordering from `c201069fac` This should fix build on vs2013 Found-by: Ferdinand Oeinck <ferdo@bigroses.demon.nl> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 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

Reimar Döffinger	177aec1257	Do not free BITMAPINFOHEADER before we are done using it. Fixes trac ticket #396. Completely untested. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 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

Diego Elio Pettenò	66355be3c3	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. (cherry picked from commit `c6610a216e`)	14 years ago
