Diego Biurrun	fcbdd605b5	nut: Use correct function pointer casts instead of void* Fixes several warnings of the type libavformat/nut.c:207:42: warning: ISO C forbids conversion of function pointer to object pointer type [-Wpedantic]	8 years ago
Diego Biurrun	07eea5a5de	nut: Drop pointless TRACE level debug code The code has little usefulness and uses the __PRETTY_FUNCTION__ GNU extension.	8 years ago
Anton Khirnov	83548fe894	lavf: fix usage of AVIOContext.seekable It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.	8 years ago
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	c3f9ebf743	lavf: make av_set_pts_info private. It's supposed to be called only from (de)muxers.	13 years ago
Reimar Döffinger	bb3244dee2	Replace all usage of strcasecmp/strncasecmp All current usages of it are incompatible with localization. For example strcasecmp("i", "I") != 0 is possible, but would break many of the places where it is used. Instead use our own implementations that always treat the data as ASCII.

Anton Khirnov	a2faa95151	lavf: make some seeking functions private Specifically av_update_cur_dts(), av_seek_frame_binary() and av_gen_search(). They are not supposed to be called outside lavf.	13 years ago
Anton Khirnov	1fa395e471	lavf: use avpriv_ prefix for ff_new_chapter(). It's used in libavdevice.	13 years ago
Anton Khirnov	84ad31ff18	lavf: replace av_new_stream->avformat_new_stream part II. Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.	13 years ago
