* rtpdec: experimental VP9 depacketizer (draft 0)Thomas Volkert2015-03-05
| | | | | | The code was tested with live555 server. Signed-off-by: Martin Storsjö <martin@martin.st>
* asf: do not export XMP metadata by defaultVittorio Giovara2015-03-03
| | | | | | | | | | | Similarly to what has been done for MOV, display XMP metadata only when users explicitly require it. The Extensible Metadata Platform tag can contain various kind of data which are not strictly related to the video file, such as history of edits and saves from the project file.

* movenc: Add an option for delaying writing the moov with empty_moovMartin Storsjö2015-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | This delays writing the moov until the first fragment is written, or can be flushed by the caller explicitly when wanted. If the first sample in all streams is available at this point, we can write a proper editlist at this point, allowing streams to start at something else than dts=0. For AC3 and DNXHD, a packet is needed in order to write the moov header properly. This isn't added to the normal behaviour for empty_moov, since the behaviour that ftyp+moov is written during avformat_write_header would be changed. Callers that split the output stream into header+segments (either by flushing manually, with the custom_frag flag set, or by just differentiating between data written during avformat_write_header and the rest) will need to be adjusted to take this option into use. For handling streams that start at something else than dts=0, an alternative would be to use different kinds of heuristics for guessing the start dts (using AVCodecContext delay or has_b_frames together with the frame rate), but this is not reliable and doesn't necessarily work well with stream copy, and wouldn't work for getting the right initialization data for AC3 or DNXHD either.

* libavformat: Add a muxer wrapping mpegts encoding into RTPMartin Storsjö2014-12-18
| | | | | | | | | | | | | | | Since this structurally is quite different from normal RTP (multiple streams are muxed into one single mpegts stream, which is packetized into one single RTP session), it is kept as a separate muxer. Since this structurally also behaves differently than normal RTP, all of the other muxers that do chained RTP muxing (rtsp, sap, mp4) would need to be updated similarly to handle this - in particular, creating one single rtp_mpegts muxer for the whole presentation instead of one rtp muxer per stream. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtp: Initial H.261 supportThomas Volkert2014-12-18
| | | | | | | | | | | | | | The packetizer only supports splitting at GOB headers - if such aren't available frequently enough, it splits at any random byte offset (not at a macroblock boundary either, which would be allowed by the spec) and sends a payload header pretend that it starts with a GOB header. As long as a receiver doesn't try to handle such cases cleverly but just drops broken frames, this shouldn't matter too much in practice. Signed-off-by: Martin Storsjö <martin@martin.st>
* mov: parse XMP metadata on demandVittorio Giovara2014-12-08
| | | | | | | | | The Extensible Metadata Platform tag can contain various kind of data which are not strictly related to the video file, such as history of edits and saves from the project file. So display XMP metadata only when the user explicitly requires it. Based on a patch by Marek Fort <marek.fort@chyronhego.com>.

* lavf: Add an MPEG-DASH ISOFF segmenting muxerMartin Storsjö2014-11-17
| | | | | | | | | | | | | | | | | | This is mostly to serve as a reference example on how to segment the output from the mp4 muxer, capable of writing the segment list in four different ways: - SegmentTemplate with SegmentTimeline - SegmentTemplate with implicit segments - SegmentList with individual files - SegmentList with one single file per track, and byte ranges The muxer is able to serve live content (with optional windowing) or create a static segmented MPD. In advanced cases, users will probably want to do the segmenting in their own application code. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Add support for writing sidx atoms for DASH segmentsMartin Storsjö2014-11-17
| | | | | | | | | | A flag "dash" is added, which enables the necessary flags for creating DASH compatible fragments. When this is enabled, one sidx atom is written for each track before every moof atom. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Write correct presentation timestamps in tfraMartin Storsjö2014-11-07
| | | | | | | Previously we wrote decoding timestamps here, while the specs say it should be presentation timestamps. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Add an option for avoiding negative timestampsMichael Niedermayer2014-11-07
| | | | | | | | | | | This is the same logic as is invoked on AVFMT_TS_NEGATIVE, but which can be enabled manually, or can be enabled in muxers which only need it in certain conditions. Also allow using the same mechanism to force streams to start at 0. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Add a flag for using default-base-is-moof in tfhd atomsMartin Storsjö2014-10-29
| | | | | | | | | | | | Similarly to the omit_tfhd_offset flag added in e7bf085b, this avoids writing absolute byte positions to the file, making them more easily streamable. This is a new feature from 14496-12:2012, so application support isn't necessarily too widespread yet (support for it in libav was added in 20f95f21f in July 2014).

* hlsenc: Add parameter -hls_allow_cacheJoakim Roubert2014-10-03
| | | | | | | | | | | | | The -hls_allow_cache parameter enables explicitly setting the EXT-X-ALLOW-CACHE tag in the manifest file. That tag indicates whether the client MAY or MUST NOT cache downloaded media segments for later replay. Valid values are 1 (=YES) or 0 (=NO) and the EXT-X-ALLOW-CACHE will not show in the manifest for other values (or if -hls_allow_cache is not used. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | events happen. The only flags, for now, indicate if metadata was updated and are set after each call to av_read_frame(). This comes with the caveat that, on stream start, it might not be set properly as packets might be buffered in AVFormatContext.packet_buffer before being given to the user in av_read_frame().

* lavf: switch to AVStream.time_base as the hint for the muxer timebaseAnton Khirnov2014-06-18
| | | | | | | | | | | | Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).
* oggenc: Support flushing the muxerMartin Storsjö2014-06-04
| | | | | | | | | This allows the caller to write all buffered data to disk, allowing the caller to know at what byte position in the file a certain packet starts (any packet written after the flush will be located after that byte position). Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: improve handling of sparse streams when muxingLuca Barbato2014-02-04
| | | | | | | | | | | | | | | | | | Currently ff_interleave_packet_per_dts() waits until it gets a frame for each stream before outputting packets in interleaved order. Sparse streams (i.e. streams with much fewer packets than the other streams, like subtitles or audio with DTX) tend to add up latency and in specific cases end up allocating a large amount of memory. Emit the top packet from the packet_buffer if it has a time delta larger than a specified threshold. Original report of the issue and initial proposed solution by mus.svz@gmail.com.
