* avformat: deprecate unused MP4A_LATM flagGyan Doshi2018-06-13
| | | | | | | A generic lavf flag for AAC LATM packetization for the RTP muxer was added in ef409645f0 and then made inert 20 days later in 0832122880 when a private muxer option was added and the generic flag no longer read.
* avdevice/decklink_dec: capture timecode to metadata when requestedJon Morley2018-06-13
| | | | | | | | | | If the user provides a valid timecode_format look for timecode of that format in the capture and if found store it on the video avstream's metadata. Slightly modified by Marton Balint to capture per-frame timecode as well. Signed-off-by: Marton Balint <cus@passwd.hu>

* avfilter/drawtext: present 'hms' formatted 'pts' in 24h formatVishwanath Dixit2018-06-04
| | | | | | | | | | | | HMS is formatted as HH:MM:SS.mmm, but, HH part is not limited to 24 hours. For example, the the drawn text may look like this: 243029:20:30.342. To present the timestamp in more readable and user friendly format, this patch provides an additional option to limit the hour part in the range 0-23. Note: Actually the above required format can be obtained with format options 'localtime' and 'gmtime', but, milliseconds part is not supported in those formats.

* avformat/movenc: creating producer reference time (PRFT) boxVishwanath Dixit2018-05-29
| | | | | | | | | The producer reference time box supplies relative wall-clock times at which movie fragments, or files containing movie fragments (such as segments) were produced. The box is mainly useful in live streaming use cases. A media player can parse the box and utilize the time fields to measure and improve the latency during real time playout.
* avformat/dashenc: Added option for Segment file formatKarthick Jeyapal2018-05-28
| | | | | | | | Right now segment file format is chosen to be either mp4 or webm based on the codec format. This patch makes that choice configurable by the user, instead of being decided by the muxer. Also with this change per-stream choice segment file format(based on codec type) is not possible. All the output audio and video streams should be in the same file format.

* avformat/mpegts: add merge_pmt_versions optionAman Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new optional flag makes it easier to deal with mpegts samples where the PMT is updated and elementary streams move to different PIDs in the middle of playback. Previously, new AVStreams were created per PID, and it was up to the user to figure out which streams had migrated to a new PID (by iterating over the list of AVProgram and making guesses), and switch seamlessly to the new AVStream during playback. Transcoding or remuxing these streams with ffmpeg on the CLI was also quite painful, and the user would need to extract each set of PIDs into a separate file and then stitch them back together. With this new option, the mpegts demuxer will automatically detect PMT changes and feed data from the new PID to the original AVStream that was created for the orignal PID. For mpegts samples with stream_identifier_descriptor available, the unique ID is used to merge PIDs together. If the stream id is not available, the demuxer attempts to map PIDs based on their position within the PMT. With this change, I am able to playback and transcode/remux these two samples which previously caused issues: https://tmm1.s3.amazonaws.com/pmt-version-change.ts https://kuroko.fushizen.eu/videos/pid_switch_sample.ts I also have another longer sample in which the PMT changes repeatedly and ES streams move to different pids three times during playback: https://tmm1.s3.amazonaws.com/multiple-pmt-change.ts Demuxing this sample with the new option shows several new log messages as the PMT changes are handled: [mpegts] detected PMT change (program=1, version=3/6, pcr_pid=0xf98/0xfb7) [mpegts] re-using existing video stream 0 (pid=0xf98) for new pid=0xfb7 [mpegts] re-using existing audio stream 1 (pid=0xf99) for new pid=0xfb8 [mpegts] re-using existing audio stream 2 (pid=0xf9a) for new pid=0xfb9 [mpegts] detected PMT change (program=1, version=6/3, pcr_pid=0xfb7/0xf98) [mpegts] detected PMT change (program=1, version=3/4, pcr_pid=0xf98/0xf9b) [mpegts] re-using existing video stream 0 (pid=0xf98) for new pid=0xf9b [mpegts] re-using existing audio stream 1 (pid=0xf99) for new pid=0xf9c [mpegts] re-using existing audio stream 2 (pid=0xf9a) for new pid=0xf9d [mpegts] detected PMT change (program=1, version=4/5, pcr_pid=0xf9b/0xfa9) [mpegts] re-using existing video stream 0 (pid=0xf98) for new pid=0xfa9 [mpegts] re-using existing audio stream 1 (pid=0xf99) for new pid=0xfaa [mpegts] re-using existing audio stream 2 (pid=0xf9a) for new pid=0xfab [mpegts] detected PMT change (program=1, version=5/6, pcr_pid=0xfa9/0xfb7) Signed-off-by: Aman Gupta <aman@tmm1.net>
* 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: add skip_unknown_pmt optionAman Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some filtered mpegts streams may erroneously include PMTs for programs that are not advertised in the PAT. This confuses ffmpeg and most players because multiple audio/video streams are created and it is unclear which ones actually contain data. See for example https://tmm1.s3.amazonaws.com/unknown-pmts.ts In this sample, the PAT advertises exactly one program. But the pid it points to for the program's PMT contains PMTs for other programs as well. This is because the broadcaster decided to re-use the same pid for multiple program PMTs. The hardware that filtered the original multi-program stream into a single-program stream did so by rewriting the PAT to contain only the program that was requested. But since it just passed through the PMT pid referenced in the PAT, multiple PMTs are still present for the other programs.

* configure: error out on unsupported MSVC versionsRostislav Pehlivanov2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | The FATE tests for MSVC versions older than 2013 are untested in FATE and apparently are no longer supported. This commit makes the configure process error out in case an older version is used, and suggests to use a supported version of MSVC to compile. This also changes the documentation to reflect this. As discussed on IRC: 2018-05-12 19:45:16 jamrial then again, most of those were for old msvc, and i think we're not supporting versions older than 2013 (first one c99 compliant) anymore 2018-05-12 19:45:43 +JEEB yea, I think 2013 update 2 is needed 22:53 <@atomnuker> nevcairiel: which commit broke/unsupported support for msvc 2013? 23:23 <@atomnuker> okay, it was JEEB 23:25 <+JEEB> which was for 2012 and older 23:25 <+JEEB> and IIRC we no longer test those in FATE so that was my assumption 23:26 <+JEEB> 2013 is when MS got trolled enough to actually update their C part 23:26 <+JEEB> aand actually advertised FFmpeg support 23:26 <+JEEB> (although it was semi-failing until VS2013 update 1 or 2) Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
