* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* avformat: Avoid allocation for AVFormatInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | | | | Do this by allocating AVFormatContext together with the data that is currently in AVFormatInternal; or rather: Put AVFormatContext at the beginning of a new structure called FFFormatContext (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVFormatInternal altogether. The biggest simplifications occured in avformat_alloc_context(), where one can now simply call avformat_free_context() in case of errors.

* avformat: Add internal flags for AV(In|Out)putFormatAndreas Rheinhardt2021-07-07
| | | | | | | | | | | | | | | | Both AVInputFormat and AVOutputFormat currently lack an equivalent to AVCodec's caps_internal. E.g. if reading a header fails, each demuxer is currently required to clean up manually, which often means to just call the demuxer's read_close function. This could (and will) be done generically via an equivalent of FF_CODEC_CAP_INIT_CLEANUP. Because of the unholy ABI-relationship between libavdevice and libavformat adding such a flag is only possible when the ABI is open (despite the flag not being part of the public API), such as now. Therefore such a flag is also added to AVOutputFormat, despite there being no immediate use for it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat: Deprecate AVFMT_FLAG_PRIV_OPT, remove av_demuxer_open on bumpAndreas Rheinhardt2021-03-03
| | | | | | | | | | | | | | | | | | | | | | | This flag was added in 492026209b9b58eaf6d2ea56423f6b1e1a8a76a5 in conjunction with av_demuxer_open() to allow to pass private options to demuxers. It worked as follows: av_open_input_stream() (the predecessor of avformat_open_input()) would not call the read_header function if this flag is set. Instead the user could set private options of the demuxer via the format's private class after avformat_open_input() and then call av_demuxer_open() which called the format's read_header function. This approach was abandoned in e37f161e66e042d6c2c7470c4d9881df9427fc4a and av_demuxer_open() deprecated; instead the AVDictionary based way of passing private options to the demuxer was choosen. Yet AVFMT_FLAG_PRIV_OPT has never been deprecated and av_demuxer_open() never removed. This commit implements the deprecation of the flag and schedules av_demuxer_open for removal on the next major bump. Given that av_demuxer_open() has been deprecated in 2012 and that this flag is useless without it, the flag will be ignored after the next major version bump.

* avdevice/avdevice: Deprecate AVDevice Capabilities APIAndreas Rheinhardt2021-02-14
| | | | | | | | | | | | | | It has been added in 6db42a2b6b22e6f1928fafcf3faa67ed78201004, yet since then none of the necessary create/free_device_capabilities functions has been implemented, making this API completely useless. Because of this one can already simplify avdevice_capabilities_free/create and can already remove the function pointers at the next major bump; given that the documentation explicitly states that av_device_capabilities is not to be used by a user, it's options can already be removed (save for the sentinel).

* avformat: remove some mpegts details from AVStreamMarton Balint2021-01-09
| | | | | | | | | | | | | | | | These fields were added to support -merge_pmt_versions, but the mpegts demuxer is also keeping track its programs internally, so that should be a better place to handle it. Also it is not a very good idea to keep fields like program_num or pmt_stream_idx in an AVStream, because a single stream can be part of multiple programs, multiple PMTs, so the stream attributes can refer to any program the stream is part of. Since they are not part of public API, lets simply remove them, or rather replace them with placeholders for ABI compatibility with libavdevice. Signed-off-by: Marton Balint <cus@passwd.hu>

| | | | | | | This struct is for internal use of avformat_find_stream_info(), so it should not be exposed in public headers. Keep a stub pointer in its place to avoid changing AVStream layout, since e.g. ffmpeg.c accesses some fields located after it (even though they are marked as private).
