* Keep including the full version.h when headers are included externallyMartin Storsjö2022-03-19
| | | | | | | | | This avoids unnecessary churn and build breakage for users, by making sure the whole version.h is included like it has been so far, while keeping the benefit of not needing to rebuild most files in the ffmpeg tree on minor/micro bumps.

* avformat/mux: Peek into the muxing queue for avoid_negative_tsAndreas Rheinhardt2022-01-21
| | | | | | | | | | | Peeking into the muxing queue can improve the estimate of the lowest timestamp needed for avoid_negative_ts in case the lowest timestamp is in a packet other than the first packet to be muxed. This fixes tickets #4536 and #5784 as well as the output from the matroska-avoid-negative-ts FATE-test. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat: introduce AVFormatContext io_close2 which returns an intMarton Balint2021-12-12
| | | | | | | | | | | | | | | | | Otherwise there is no way to detect an error returned by avio_close() because ff_format_io_close cannot get the return value. Checking the return value of the close function is important in order to check if all data was successfully written and the underlying close() operation was successful. It can also be useful even for read mode because it can return any pending AVIOContext error, so the user don't have to manually check AVIOContext->error. In order to still support if the user overrides io_close, the generic code only uses io_close2 if io_close is either NULL or the default io_close callback.

* avformat/avformat: Add AVStream parameter to check_bitstream() sigAndreas Rheinhardt2021-11-27
| | | | | | | | | | For most check_bitstream() functions this just avoids having to dereference s->streams[pkt->stream_index] themselves; but for meta-muxers it will allow to forward the packet to stream with a different stream_index (belonging to a different AVFormatContext) without using a spare packet.

* avformat/mux: Don't use stack packet when writing interleaved packetsAndreas Rheinhardt2021-10-03
| | | | | | | | | | | | | | | | | | | Currently the interleave_packet functions use a packet for a new packet to be interleaved (may be NULL if there is none) and a packet for output; said packet is always a stack packet in interleaved_write_packet(). But all the interleave_packet functions in use first move the packet to the packet list and then check whether a packet can be returned, i.e. the effective lifetime of the new packet ends before the packet for output is touched. So one can use one packet both for input and output by adding a new parameter that indicates whether there is a packet to add to the packet list; there is just one complication: In case the muxer is flushed, there is no packet available. This can be solved by reusing one of the packets from AVFormatInternal. They are currently unused when flushing in av_interleaved_write_frame().

* avformat/avformat: Clarify documentation of av_interleaved_write_frame()Andreas Rheinhardt2021-10-03
| | | | | | | | | | | | | | | | | | | The earlier documentation claimed that av_interleaved_write_frame() always orders by dts, which is not necessarily true when using muxers with custom interleavement functions or the audio_preload option. Furthermore, the documentation stated that libavformat takes ownership of the reference of the provided packet (if it is refcounted) and that the caller may not access the data through this reference after the function returns. This suggests that the returned packet is not blank, but instead still contains some set, but invalid fields, which implies that it would be dangerous to unreference this packet again. But this is not true: av_interleaved_write_frame()'s actual behaviour is to always output blank packet (even on error). This commit documents this fact so that callers know that they can directly reuse this packet. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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>
