| | | | | This also updates fate-lavf-mov_rtphint as there the SDP is included in the muxed file.
* avformat: add AV1 RTP depacketizer and packetizerChris Hodges2025-02-261-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Add RTP packetizer and depacketizer according to (most) of the official AV1 RTP specification. This enables streaming via RTSP between ffmpeg and ffmpeg and has also been tested to work with AV1 RTSP streams via GStreamer. It also adds the required SDP attributes for AV1. AV1 RTP encoding is marked as experimental due to draft specification status, debug amount reduced and other changes suggested by Tristan. Added optional code for searching the sequence header to determine the first packet for broken AV1 encoders / parsers. Stops depacketizing on corruption until next keyframe, no longer prematurely issues packet on decoding if temporal unit was not complete yet.

* avcodec/mpeg4audio: Unavpriv and deduplicate mpeg4audio_sample_ratesAndreas Rheinhardt2022-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | avpriv_mpeg4audio_sample_rates has a size of 64B and it is currently avpriv; a clone of it exists in aacenctab.h and from there it is inlined in aacenc.c (which also uses the avpriv version) and in the FLV muxer. This means that despite it being avpriv both libavformat as well as libavcodec have copies already. This situation is clearly suboptimal. Given the overhead of exporting symbols (for x64 Elf/Linux/GNU: 2x2B version, 2x24B .dynsym, 24B .rela.dyn, 8B .got, 4B hash + twice the size of the name (here 31B)) the object is unavprived, i.e. duplicated into libavformat when creating a shared build; but the duplicates in the AAC encoder and FLV muxer are removed. This involves splitting of the sample rate table into a file of its own; this allowed to break some spurious dependencies (e.g. both the AAC encoder as well as the Matroska demuxer actually don't need the mpeg4audio_get_config stuff).

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-231-87/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. 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 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>
