| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libavformat/img2.h: New field export_path_metadata to VideoDemuxData to only allow the use of the extra metadata upon explicit user request, for security reasons. libavformat/img2dec.c: Modify image2 demuxer to make available two special metadata entries called lavf.image2dec.source_path and lavf.image2dec.source_basename, which represents, respectively, the complete path to the source image for the current frame and the basename i.e. the file name related to the current frame. These can then be used by filters like drawtext and others. The metadata fields will only be available when explicitly enabled with image2 option -export_path_metadata 1. doc/demuxers.texi: Documented the new metadata fields available for image2 and how to use them. doc/filters.texi: Added an example on how to use the new metadata fields with drawtext filter, in order to plot the input file path to each output frame. Usage example: ffmpeg -f image2 -export_path_metadata 1 -pattern_type glob -framerate 18 -i '/path/to/input/files/*.jpg' -filter_complex drawtext="fontsize=40:fontcolor=white: fontfile=FreeSans.ttf:borderw=2:bordercolor=black: text='%{metadata\:lavf.image2dec.source_basename\:NA}':x=5:y=50" output.avi Fixes #2874.

* avformat/mpegts: add merge_pmt_versions optionAman Gupta2018-05-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/mpegts: add skip_unknown_pmt optionAman Gupta2018-05-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* avformat/hls: enable http_multiple only for http/1.1 serversAman Gupta2017-12-261-1/+1
| | | | | | | | Some http/1.0 implementations, like python's SimpleHTTPServer, can only support one client connection at a time. Making a second request while the first is still connected leads to a deadlock. This change enables multiple connections for http/1.1 servers only, which need to support keepalive by default and should have no problem with concurrent requests.

* avformat/hls: add http_multiple optionAman Gupta2017-12-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | This improves network throughput of the hls demuxer by avoiding the latency introduced by downloading segments one at a time. The problem is particularly noticable over high-latency network connections: for instance, if RTT is 250ms, there will a 250ms idle period between when one segment response is read and the next one starts. The obvious solution to this is to use HTTP pipelining, where a second request can be sent (on the persistent http/1.1 connection) before the first response is fully read. Unfortunately the way the http protocol is implemented in avformat makes implementing pipleining very complex. Instead, this commit simulates pipelining using two separate persistent http connections. This has the advantage of working independently of the http_persistent option, and can be used with http/1.0 servers as well. The pair of connections is swapped every time a new segment starts downloading, and a request for the next segment is sent on the secondary connection right away. This means the second response will be ready and waiting by the time the current response is fully read. Signed-off-by: Aman Gupta <aman@tmm1.net> Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi>
* avformat/hls: add http_persistent optionAman Gupta2017-12-221-0/+4
| | | | | | | | | | | | | | | This teaches the HLS demuxer to use the HTTP protocols multiple_requests=1 option, to take advantage of "Connection: Keep-Alive" when downloading playlists and segments from the HLS server. With the new option, you can avoid TCP connection and TLS negotiation overhead, which is particularly beneficial when streaming via a high-latency internet connection.
