Diego Biurrun	ca1e5eea0c	Remove some pointless TRACE level debug code This also kills some warnings with certain compiler options.	8 years ago
Diego Biurrun	c3dad1bf3b	nsv: Drop unnecessary TRACE level debug code The output is rather silly and the code uses non-standard __FUNCTION__.	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
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
Vittorio Giovara	1a3eb042c7	Replace av_dlog with normal av_log at trace level This applies to every library where performance is not critical.	10 years ago

Diego Biurrun	6df5c528ca	Move some conditionally used variables into the block where they are used. This allows dropping the av_unused argument from them.	13 years ago
Diego Biurrun	7331b6e718	Drop some completely unnecessary av_unused attributes.	13 years ago

Alex Converse	8fd8a48263	nsvdec: Be more careful with av_malloc(). Check results for av_malloc() and fix an overflow in one call. Related to CVE-2011-3940. Based in part on work from Michael Niedermayer. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	13 years ago

Anton Khirnov	6e9651d106	lavf: remove AVFormatParameters from AVFormatContext.read_header signature	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
Diego Biurrun	20566eb0f0	Replace outdated references to ffmpeg tool with avconv.	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
Anton Khirnov	dfc2c4d900	lavf: use designated initialisers for all (de)muxers. It's more readable and less prone to breakage.	14 years ago

Diego Biurrun	35fa0d4758	nsvdec: Propagate error values instead of returning 0 in nsv_read_header(). This eliminates a warning about a set-but-unused variable.	14 years ago
Diego Biurrun	919d7a345a	Replace DEBUG_SEEK/DEBUG_SI + av_log combinations by av_dlog.	14 years ago
Anton Khirnov	d2d67e424f	Remove all uses of now deprecated metadata functions.	14 years ago
Mans Rullgard	5e1166b31b	Mark some variables with av_unused Most of these variables are only used in av_dlog statements, some are required but not used by other macros. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Thierry Foucu	45faf7fcd3	nsv: Fix misdetection of MP3 files as NSV. If an MP3 file contains the string NSVs, the NSV probe will confuse it for an NSV file. Check for 0xBEEF after a Video/Audio chunk to achieve more accuracy. Signed-off-by: Diego Biurrun <diego@biurrun.de>	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
