* avformat/demux: Use enum AVCodecID for raw_codec_idAndreas Rheinhardt2024-03-071-1/+1

* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-07274-1812/+2028
| | | | | | | | | | | | | | | | | | | | | This commit does for AVInputFormat what commit 59c9dc82f450638a3068deeb1db5c56f6d155752 did for AVOutputFormat: It adds a new type FFInputFormat, moves all the internals of AVInputFormat to it and adds a now reduced AVInputFormat as first member. This does not affect/improve extensibility of both public or private fields for demuxers (it is still a mess due to lavd). This is possible since 50f34172e0cca2cabc5836308ec66dbf93f5f2a3 (which removed the last usage of an internal field of AVInputFormat in fftools). (Hint: tools/probetest.c accesses the internals of FFInputFormat as well, but given that it is a testing tool this is not considered a problem.)

| | | | | | | | | | | | | Do not propagate the return value of avformat_write_header(), as it contains the information whether the output had already been initialized in avformat_init_output(), but this is set generically; the return value of FFOutputFormat.write_header is not documented at all (and is currently ignored if >= 0), but it is more future-proof to simply return 0 on success.

* avformat/mpegts: detect synchronous metadata KLV more reliablyMarton Balint2024-03-041-2/+5
| | | | | | | | | | | | | | | | The mpegts code historically tries to strip (the first) metadata access unit header from synchronous KLV metadata, but the detection for such streams was unreliable causing strips of asynchronous metadata or ID3 as well. MISB ST 1402 specifies required stream type, stream id and registration descriptor (which eventually maps to the codec ID) so let's use all of these for reliable detection. Fixes a regression caused by 468615f2045da325e0f73e8e668d49cf456ccb37. Fixes ticket #10828, #10883. Signed-off-by: Marton Balint <cus@passwd.hu>

* avformat/wavdec: dynamically set max_size by defaultMarton Balint2024-03-021-1/+18
| | | | | | | | | | | | | The wav demuxer by default tried to demux 4096-byte packets which caused packets with very few number of samples for files with high channel count. This caused a significant overhead especially since the latest ffmpeg.c threading changes. So let's use a similar approach for selecting audio frame size which is already used in the PCM demuxer, which is to read 25 times per second but at most 1024 samples.

* flvdec: Honor the "flv_metadata" option for the "datastream" metadata fieldMartin Storsjö2024-02-201-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default the option "flv_metadata" (internally using the field name "trust_metadata") is set to 0, meaning that we don't allocate streams based on information in the metadata, only based on actual streams we encounter. However the "datastream" metadata field still would allocate a subtitle stream. When muxing, the "datastream" field is added if either a data stream or subtitle stream is present - but the same metadata field is used to preemtively create a subtitle stream only. Thus, if the field was added due to a data stream, not a subtitle stream, the demuxer would create a stream which won't get any actual packets. If there was such an extra, empty subtitle stream, running avformat_find_stream_info still used to terminate within reasonable time before 3749eede66c3774799766b1f246afae8a6ffc9bb. After that commit, it no longer would terminate until it reaches the max analyze duration, which is 90 seconds for flv streams (see e6a084641aada7a2e4672172f2ee26642800a361, 24fdf7334d2bb9aab0abdbc878b8ae51eb57c86b and f58e011a1f30332ba824c155078ca701e29aef63). Before that commit (which removed the deprecated AVStream.codec), the "st->codecpar->codec_id = AV_CODEC_ID_TEXT", set within the demuxer, would get propagated into st->codec->codec_id by numerous avcodec_parameters_to_context(st->codec, st->codecpar), then further into st->internal->avctx->codec_id by update_stream_avctx within read_frame_internal in libavformat/utils.c (demux.c these days).
