* avformat/rtpenc: Add flag AVFMT_NODIMENSIONS.Koushik Dutta2025-03-291-1/+9
| | | | | | | | | | | | | Not all rtp formats require the video dimensions to be available up front. H264 and HEVC will send them as stream parameters. The flag is restrictive and prevents RTP repacketization without parsing the codec information out of the stream. This change checks to see if the codec parameters are available on the rtp formats that need it.

* avformat: add AV1 RTP depacketizer and packetizerChris Hodges2025-02-261-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-091-7/+8
| | | | | | | | | | | | | | This commit does for AVOutputFormat what commit 20f972701806be20a77f808db332d9489343bb78 did for AVCodec: It adds a new type FFOutputFormat, moves all the internals of AVOutputFormat to it and adds a now reduced AVOutputFormat as first member. This does not affect/improve extensibility of both public or private fields for muxers (it is still a mess due to lavd).

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.
* | avformat/rtpenc: Fix integer overflow in NTP_TO_RTP_FORMATBoris Nagels2016-03-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | RTCP synchronization packet was broken since commit in ffmpeg version > 2.8.3 (commit: e04b039b1528f4c7df5c2b93865651bfea168a19) Since this commit (2e814d0329aded98c811d0502839618f08642685) "rtpenc: Simplify code by introducing a macro for rescaling NTP timestamps", NTP_TO_RTP_FORMAT uses av_rescale_rnd() function to add the data to the packet. This causes an overflow in the av_rescale_rnd() function and it will return INT64_MIN. Causing the NTP stamp in the RTCP packet to have an invalid value. Github: Closes #182 Reverting commit '2e814d0329aded98c811d0502839618f08642685' solves the problem.

This makes the AMR and AAC packetization slightly less efficient, since we set a possibly unnecessarily high max_frames_per_packet. (These packetizers end up doing a memmove of the TOC bytes if sending a packet before max_frames_per_packet is achieved, and we end up setting max_frames_per_packet to a value that should be high enough for most uses.) All packetizers that use max_frames_per_packet now set it either to a default value, or to a value calculated based on other parameters, so none of them rely on the previous default setting. For iLBC, copy one frame at a time, to allow checking the timestamp range for each of them - basically doing potentially multiple loops to simplify the code instead of trying to calculate the number of frames to buffer while honoring s1->max_delay. This is in preparation for reducing the coupling between libavformat and libavcodec, by not having the muxers use the encoder field frame_size (which may not be available during e.g. stream copy).
