* 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.
* 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`.

* rmdec: Use the AVIOContext given as parameter in rm_read_metadata()Michael Niedermayer2013-07-07
| | | | | | | | | | | | | | | This fixes crashes when playing back certain RealRTSP streams. When invoked from the RTP depacketizer, the full realmedia demuxer isn't invoked, but only certain functions from it, where a separate AVIOContext is passed in as parameter (for the buffer containing the data to parse). The functions called from within those entry points should only be using that parameter, not s->pb. In the depacketizer case, s is the RTSP context, where ->pb is null.

* lavf: deprecate r_frame_rate.Anton Khirnov2012-07-29
| | | | | | | | | | | | | | | | | | | | According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.

* rm: prevent infinite loops for index parsing.Ronald S. Bultje2012-02-22
| | | | | | | | | Specifically, prevent jumping back in the file for the next index, since this can lead to infinite loops where we jump between indexes referring to each other, and don't read indexes that don't fit in the file.

* rmdec: when using INT4 deinterleaving, error out if sub_packet_h <= 1.Ronald S. Bultje2012-02-22
| | | | | | | | | We read sub_packet_h / 2 packets per line of data (during deinterleaving), which equals zero if sub_packet_h <= 1, thus causing us to not read any data, leading to an infinite loop. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* Use deinterleavers for demangling audio packets in RealMedia.Kostya Shishkov2011-08-27
| | | | | | | | | | Unlike other containers RealMedia stores its audio packets in scrambled form, with interleaver ID preceeding audio codec ID. Currently deinterleaving decision is tied to the codec while it's possible to have non-default deinterleaver with audio codec (like Int0 deinterleaver instead of specific one for Sipro).
