* Make mime-type award a bonus probe scorePeter Zebühr2025-02-261-1/+1
| | | | | | | | | | | | | | | | This changes the default behaviour of ffmpeg where content-type headers on an input gives an absolut probe score (of 75) to instead give a bonus score (of 30). This gives the probe a better chance to arrive at the correct format by (hopefully) giving a large enough bonus to push edge cases in the right direction (MPEG-PS vs MP3, I am looking at you) while also not adversly punishing clearer cases (raw ADTS marked as "audio/mpeg" for example). This patch was regression tested against 20 million recent podcast submissions (after content-type propagation was added to original-storage), and 50k Juno vodcasts submissions (dito). No adverse effects observed (but the bonus may still need tweaking if other edge cases are detected in production).

* lavf: deprecate av_format_inject_global_side_data()Anton Khirnov2024-10-161-0/+8
| | | | | | | | This function would otherwise fail to build on the next major bump, as inject_global_side_data is marked for removal. It should also never be needed, as there is now a mechanism for supplying global side data to decoders directly.

* avformat/demux: add duration_probesize AVOptionNicolas Gaullier2024-04-021-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | Yet another probesize used to get the durations when estimate_timings_from_pts is required. It is aimed at users interested in better durations probing for itself, or because using avformat_find_stream_info indirectly and requiring exact values: for concatdec for example, especially if streamcopying above it. The current code is a performance trade-off that can fail to get video stream durations in a scenario with high bitrates and buffering for files ending cleanly (as opposed to live captures): the physical gap between the last video packet and the last audio packet is very high in such a case. Default behaviour is unchanged: 250k up to 250k << 6 (step by step). Setting this new option has two effects: - override the maximum probesize (currently 250k << 6) - reduce the number of steps to 1 instead of 6, this is to avoid detecting the audio "too early" and failing to reach a video packet. Even if a single audio stream duration is found but not the other audio/video stream durations, there will be a retry, so at the end the full user-overriden probesize will be used as expected by the user.

* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-071-98/+0
| | | | | | | | | | | | | | | | | | | | | This commit does for AVInputFormat what commit 59c9dc82f450638a3068deeb1db5c56f6d155752 did for AVOutputFormat: It adds a new type FFInputFormat, moves all the internals of AVInputFormat to it and adds a now reduced AVInputFormat as first member. This does not affect/improve extensibility of both public or private fields for demuxers (it is still a mess due to lavd). This is possible since 50f34172e0cca2cabc5836308ec66dbf93f5f2a3 (which removed the last usage of an internal field of AVInputFormat in fftools). (Hint: tools/probetest.c accesses the internals of FFInputFormat as well, but given that it is a testing tool this is not considered a problem.)

This also enables exporting other stream items like thumbnails, which may be present in non tiled HEIF images too. For those, the primary stream will be tagged with the default disposition.

| | | | | | | | | | The existing (and upcoming) available group types are meant to combine several streams for presentation, with the result being treated as if it was a stream itself.

* avformat/avformat: use the side data from AVStream.codecparJames Almer2023-10-061-1/+26
| | | | | | | | | | | | Deprecate AVStream.side_data and its helpers in favor of the AVStream's codecpar.coded_side_data. This will considerably simplify the propagation of global side data to decoders and from encoders. Instead of having to do it inside packets, it will be available during init(). Global and frame specific side data will therefore be distinct. Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/avformat: Deprecate AVFMT_ALLOW_FLUSHAndreas Rheinhardt2023-10-031-2/+4
| | | | | | | | | | | | | | | It is of no value to the user, because every muxer can always be flushed with a NULL packet. As its documentation shows ("If not set, the muxer will not receive a NULL packet in the write_packet function") it is actually an internal flag that has been publically exposed because there was no internal flags field for output formats for a long time. But now there is and so use it by replacing the public flag with a private one.

* avformat/avformat: Avoid including codec.h, frame.hAndreas Rheinhardt2023-09-071-13/+16
| | | | | | | | | | | | | | | | AVCodec is only ever used as an incomplete type (i.e. via a pointer to an AVCodec) in avformat.h and it is not really part of the core of avformat.h or libavformat; almost none of our internal users make use of it (and none make use of hwcontext.h, which is implicitly included). So switch to use struct AVCodec, but continue to include codec.h for external users for compatibility. Also, do the same for AVFrame and frame.h, which is implicitly included by codec.h (via lavu/hwcontext.h). Also, remove an unnecessary inclusion of <time.h>.

| | | | | | | | | | | According to its documentation it returns "pts of the last muxed packet + its duration", but the value it actually returns right now is (possibly guessed) dts after muxer-internal bitstream filtering (if any). This function was added for ffmpeg.c, but it is not used there anymore. Since the value it returns is ill-defined and so inappropriate for any serious use, deprecate it.

* avformat: introduce AVFormatContext io_close2 which returns an intMarton Balint2021-12-121-0/+13
| | | | | | | | | | | | | | | | | 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.
