| | | | | | | 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).

* avformat/avformat.h: Correct some commentsAndreas Rheinhardt2020-04-01
| | | | | | | | | | | | | | | | | 1. When set_parameters was removed from AVOutputFormat in 2fb75019, it was forgotten to remove the comment pertaining to it. Said comment now appeared to apply to interleave_packet(); it is of course nonsense and has been replaced by an accurate description. 2. The description of av_write_uncoded_frame() suggested av_interleaved_write_frame() as a replacement if the input is not already correctly interleaved; it also referred to said function for details. Given that said function can't write AVFrames and that the specifics of writing uncoded frames are explained in the description of av_interleaved_write_uncoded_frame(), both references have been fixed. 3. Removed an outdated comment about avformat_seek_file(). Reviewed-by: Marton Balint <cus@passwd.hu> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/avformat: Update av_read_frame() documentationAndreas Rheinhardt2020-03-29
| | | | | | | | | | | | | This commit updates the documentation of av_read_frame() to match its actual behaviour in several ways: 1. On success, av_read_frame() always returns refcounted packets. 2. It can handle uninitialized packets. 3. On error, it always returns blank packets. This will allow callers to not initialize or unref unnecessarily.

* avformat: add fields to AVProgram/AVStream for PMT change trackingAman Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These fields will allow the mpegts demuxer to expose details about the PMT/program which created the AVProgram and its AVStreams. In mpegts, a PMT which advertises streams has a version number which can be incremented at any time. When the version changes, the pids which correspond to each of it's streams can also change. Since ffmpeg creates a new AVStream per pid by default, an API user needs the ability to (a) detect when the PMT changed, and (b) tell which AVStream were added to replace earlier streams. This has been a long-standing issue with ffmpeg's handling of mpegts streams with PMT changes, and I found two related patches in the wild that attempt to solve the same problem: The first is in MythTV's ffmpeg fork, where they added a void (*streams_changed)(void*); to AVFormatContext and call it from their fork of the mpegts demuxer whenever the PMT changes. The second was proposed by XBMC in https://ffmpeg.org/pipermail/ffmpeg-devel/2012-December/135036.html, where they created a new AVMEDIA_TYPE_DATA stream with id=0 and attempted to send packets to it whenever the PMT changed.

* avformat/mpegts: tag video streams with still imagesAman Gupta2018-05-17
| | | | | | | | | | | | Parses the video_stream_descriptor (H.222 2.6.2) to look for the still_picture_flag. This is exposed to the user via a new AV_DISPOSITION_STILL_IMAGE. See for example https://tmm1.s3.amazonaws.com/music-choice.ts, whose video stream only updates every ~6 seconds.

* avformat: add skip_estimate_duration_from_ptsAman Gupta2018-05-17
| | | | | | | | | | | | | | | | | | | For seekable mpegts streams, duration is calculated from pts by seeking to the end of the file for a pts and subtracting the initial pts to compute a duration. This can be expensive in terms of added latency during probe, especially when streaming over a network. This new option lets you skip the duration calculation, which is useful when you don't care about the value and want to save some overhead. This patch is particularly useful when dealing with live mpegts streams. Normally such streams are not seekable, so durations are not calculated. However in my case I am dealing with a seekable live mpegts stream (networked access to a .ts file which is still being appended to). Signed-off-by: Aman Gupta <aman@tmm1.net>

* avformat: make avformat_network_init() explicitly optionalwm42018-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was sort of optional before - if you didn't call it, networking was initialized on demand, and an ugly warning was logged. Also, the doxygen comments threatened that it would be made strictly required one day. Make it explicitly optional. I would prefer to deprecate it fully, but there might still be legitimate reasons to use this. But the average user won't need it. This is needed only for two reasons: to initialize TLS libraries like OpenSSL and GnuTLS, and winsock. OpenSSL and GnuTLS were already silently initialized on demand if the global network init function was not called. They also have various thread-safety acrobatics, which make concurrent initialization within libavformat safe. In addition, the libraries are moving towards making their global init functions safe, which removes all need for central global init. In particular, GnuTLS 3.5.16 and OpenSSL 1.1.0g have been found to have safe init functions. In all cases, they use internal reference counters to avoid that the global uninit functions interfere with concurrent uses of the library by other API users who called global init. winsock should be thread-safe as well, and maintains an internal reference counter as well. Since we still support ancient TLS libraries, which do not have this fixed, and since it's unknown whether winsock and GnuTLS reinitialization is costly in any way, don't deprecate the libavformat functions yet.
