* avformat/id3v2: Remove unnecessary indirectionAndreas Rheinhardt2020-05-25
| | | | | | | | | ff_id3v2_parse_apic/chapters/priv/priv_dict all had a parameter extra_meta of type ID3v2ExtraMeta ** as if the functions wanted to make *extra_meta point to something else. But they don't, so just use an ID3v2ExtraMeta *. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat: Forward errors where possibleAndreas Rheinhardt2019-12-12
| | | | | | | | | | It is not uncommon to find code where the caller thinks to know better what the return value should be than the callee. E.g. something like "if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit changes several instances of this to instead forward the actual error.

* avformat/aiffdec: AIFF fix in case of ANNOEduard Sinelnikov2018-01-11
| | | | | | | | | | | Apple's AIFF protocol clearly states that each chucnk which is odd sized a padding should be added. In the old version of aiffdec adding of padding was done in `get_meta`. And in case of unknown chunk name it was done in defalut case. The new version has deleted the padding in default case and added padding adding after the switch. But the new version didn't removed the padding adding in the `get_meta` function so in some cases padding was added twice which leaded to a bug.

* aiff: add support for XA ADPCMMisty De Meo2018-01-04
| | | | | | | | | Certain AIFF files encode XA ADPCM compressed audio using a chunk with the tag `APCM`. Aside from this custom chunk type, they're otherwise standard AIFF files. I've only observed these files in the Sega Saturn game Sonic Jam so far. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avformat: fix id3 chaptersLukas Stabe2017-10-05
| | | | | | | | | | | These changes store id3 chapter data in ID3v2ExtraMeta and introduce ff_id3v2_parse_chapters to parse them into the format context if needed. Encoders using ff_id3v2_read, which previously parsed chapters into the format context automatically, were adjusted to call ff_id3v2_parse_chapters. Signed-off-by: wm4 <nfxjfg@googlemail.com>

| | | | | | | | | | | | | | | | 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.

| * 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.

* | ff_id3v2_read: add option to limit ID3 magic number searchPeter Ross2014-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Several chunked formats (AIFF, IFF,DSF) store ID3 metadata within an 'ID3 ' chunk tag. If such chunks are stored sequentially, it is possible for the ID3v2 parser to confuse the chunk tag for the ID3 magic number. e.g. [1st chunk tag ('ID3 ') | chunk size] [ID3 magic number | metadata ...] [2nd chunk tag ('ID3 ') | chunk size] [ID3 magic number | metadata ...] Fixes ticket #3530.
