* lavf/mux: do not apply max_interleave_delta to subtitlesAnton Khirnov2023-11-14
| | | | | | | | | It is common for subtitle streams to have large gaps between packets. When the caller is interleaving packets from multiple files, it can easily happen that two successive subtitle packets trigger this limit, even though no excessive buffering is happening. Should fix #7064

* lavf/gifdec: do not mark as notimestampsAnton Khirnov2023-10-03
| | | | | | | | The demuxer does not set packet timestamps itself after c6b6356635f598b095606cd126f31bc6ab916225 and instead relies on the parser to do it. However, this does not matter from the caller perspective as it still happens inside the demuxer. The demuxer should thus not be flagged as not having timestamps.
* lavf/demux: restrict video parser duration handling to just GIFAnton Khirnov2023-10-03
| | | | | | The parser does not have a timebase associated with it, so in general it makes no sense for it to be exporting durations. Longer-term this should be handled more cleanly with a new parser API.
* avformat/avformat: Deprecate AVFMT_ALLOW_FLUSHAndreas Rheinhardt2023-10-03
| | | | | | | | | | | | | | | It is of no value to the user, because every muxer can always be flushed with a NULL packet. As its documentation shows ("If not set, the muxer will not receive a NULL packet in the write_packet function") it is actually an internal flag that has been publically exposed because there was no internal flags field for output formats for a long time. But now there is and so use it by replacing the public flag with a private one.

* avformat/matroskaenc: Don't create wrong packet durationsAndreas Rheinhardt2023-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | We have to write an explicit BlockDuration element (and use a BlockGroup instead of a SimpleBlock) in case the Track has a DefaultDuration that is inconsistent with the duration of the packet. The matroska-h264-remux test uses a file with coded fields where the duration of a Block is the duration of a field, not of a frame, therefore this patch writes said BlockDuration elements. (When using a BlockGroup, one has to add ReferenceBlock elements to distinguish keyframes from non-keyframes. Unfortunately, the AV1 codec mapping [1] requires us to reference all references and to really use the real references, which requires a lot of effort for basically no gain. When BlockGroups are used with AV1, the created files are most likely invalid, both before and after this patch, but this patch makes this more likely to happen.)
