* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* mpegaudiodecheader: check the header in avpriv_mpegaudio_decode_headerAnton Khirnov2015-12-12
| | | | | | Almost all the places from which this function is called already check the header manually and in the two that don't (the mp3 muxer) the check should not cause any problems.
* avpacket: Replace av_free_packet with av_packet_unrefLuca Barbato2015-10-26
| | | | | | | `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.
* Drop the unofficial extension prefix for MPEG and MPEG-TS formatsFlorent Le Coz2014-12-02
| | | | | | | | As per the RFCs: http://tools.ietf.org/html/rfc3555#page-38 http://tools.ietf.org/html/rfc3003 CC: libav-stable@libav.org
* mp3enc: write full LAME frameAnton Khirnov2014-10-24
| | | | Most importantly, it contains the encoder delay and replaygain info.
* Check mp3 header before calling avpriv_mpegaudio_decode_header().Justin Ruggles2014-06-22
| | | | | | | | As indicated in the function documentation, the header MUST be checked prior to calling it because no consistency check is done there. CC:libav-stable@libav.org
* mp3enc: Properly write bitrate value in XING headerMichael Niedermayer2014-04-12
| | | | | | | | | | | | Instead of using a fixed bitrate_idx, calculate a matching bitrate for the XING header. Using a fixed bitrate_idx causes tools such as file(1) and mediainfo(1) to report wrong bitrate and bitrate mode when using CBR.

* mp3enc: move mp3_write_xing() further up in the file.Anton Khirnov2012-02-29
| | | | It will be need by new functions called from mp3_write_trailer().
* id3v2enc: split ff_id3v2_write().Anton Khirnov2012-02-29
| | | | | This will allow writing the tag in several steps, needed for writing attached pictures.
* Replace all usage of strcasecmp/strncasecmpReimar Döffinger2011-11-06
| | | | | | | | | | | 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. Signed-off-by: Martin Storsjö <martin@martin.st>

* Do not write ID3v1 tags by defaultDiogo Franco2011-08-16
| | | | | | | | | | ID3v1 are legacy tags with several limitations; furthermore avconv/ffmpeg writes the tags in UTF-8 which probably has near-0 software support. Add a -write_id3v1 option to be able to turn it on; disabled by default. Signed-off-by: Anton Khirnov <anton@khirnov.net>
