* avformat/movenc: remove the write_clli mov flagMichael Bradshaw2020-04-13
| | | | | | | | | The clli atom is expected to be standardized soon. See http://ffmpeg.org/pipermail/ffmpeg-devel/2020-April/259529.html We now write the clli atom by default. Signed-off-by: Michael Bradshaw <mjbshaw@google.com>
* avformat/movenc: add write_clli flag to write clli atomMichael Bradshaw2020-04-01
| | | | | | | | | The clli atom isn't in ISO/IEC 14496-12:2015 so the flag is marked as experimental and the clli atom is not written by default. The clli atom is already parsed by FFmpeg in mov.c. Signed-off-by: Michael Bradshaw <mjbshaw@google.com>

* 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/movenc: support writing iTunes cover imageTimo Teräs2018-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | Fixes https://trac.ffmpeg.org/ticket/2798 This makes movenc handle AV_DISPOSITION_ATTACHED_PIC and write the associated pictures in iTunes cover atom. This corresponds to how 'mov' demuxer parses and exposes the cover images when reading. Most of the existing track handling loops properly ignore these 'virtual streams' as MOVTrack->entry is never incremented for them. However, additional tests are added as needed to ignore them. Tested to produce valid output with: ffmpeg -i movie.mp4 -i thumb.jpg -disposition:v:1 attached_pic \ -map 0 -map 1 -c copy movie-with-cover.mp4 The cover image is also copied correctly with: ffmpeg -i movie-with-cover.mp4 -map 0 -c copy out.mp4 AtomicParseley says that the attached_pic stream is properly not visible in the main tracks of the file.

* movenc: Add an option for enabling negative CTS offsetsMartin Storsjö2017-09-28
| | | | | | | | | | | | | This reduces the need for an edit list; streams that start with e.g. dts=-1, pts=0 can be encoded as dts=0, pts=0 (which is valid in mov/mp4) by shifting the dts values of all packets forward. This avoids the need for edit lists for such streams (while they still are needed for audio streams with encoder delay). This eases conformance with the DASH-IF interoperability guidelines.

| * movenc: Add an option for skipping writing the mfra/tfra/mfro trailerMartin Storsjö2016-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When writing a fragmented file, we by default write an index pointing to all the fragments at the end of the file. This causes constantly increasing memory usage during the muxing. For live streams, the index might not be useful at all. A similar fragment index is written (but at the start of the file) if the global_sidx flag is set. If ism_lookahead is set, we need to keep data about the last ism_lookahead+1 fragments. If no fragment index is to be written, we don't need to store information about all fragments, avoiding increasing the memory consumption linearly with the muxing runtime. This fixes out of memory situations with long live mp4 streams. Signed-off-by: Martin Storsjö <martin@martin.st>

It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The double meaning of the faststart flag (moving a moov atom to the start of files, making them streamable, for non-fragmented files, vs inserting a global sidx index at the start of files for fragmented files) is confusing - see 40ed1cbf1 for explanation of its origins. Since the second meaning of the flag hasn't been part of any libav release yet, just rename it to get rid of the confusion without any extra deprecation (which wouldn't get rid of the potential confusion, of users adding -movflags faststart even for fragmented files, where it isn't needed for making them "streamable"). This gets back the old behaviour, where -movflags faststart doesn't have any effect for fragmented files. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * movenc: Add a flag for indicating a discontinuous fragmentMartin Storsjö2014-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows creating a later mp4 fragment without sequentially writing the earlier ones before (when called from a segmenter). Normally when writing a fragmented mp4 file sequentially, the first timestamps of a fragment are adjusted to match the end of the previous fragment, to make sure the timestamp is the same, even if it is calculated as the sum of previous fragment durations. (And for the first packet in a file, the offset of the first packet is written using an edit list.) When writing an individual mp4 fragment discontinuously like this (with potentially writing the earlier fragments separately later), there's a risk of getting a gap in the timeline if the duration field of the last packet in the previous fragment doesn't match up with the start time of the next fragment. Using this requires setting -avoid_negative_ts make_non_negative (or -avoid_negative_ts 0). Signed-off-by: Martin Storsjö <martin@martin.st>
