* avcodec/nvenc: add support for writing mastering metadata SEI messagesJames Almer2025-02-044-1/+91
| | | | | | | Including Mastering Display and Content Light Level. Requires SDK 13.0, and only supports HEVC and AV1. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/amfenc: redesign to use hwcontext_amf.Dmitrii Ovchinnikov2025-02-045-632/+306

* avfilter/scale_amf: Add AMF VPP & super resolution filtersEvgeny Pavlov2025-02-047-0/+1038
| | | | | | | | This commit adds two AMF filters: vpp_amf & sr_amf. Both filters are using AMF hardware acceleration. vpp_amf supports simple scaling algorithms & color conversion. sr_amf supports advanced scaling algorithms such as FSR & can be used for upscaling only.
* avcodec: add amfdec.Evgeny Pavlov2025-02-045-2/+790
| | | | | | | Added AMF based h264, hevc, av1 decoders. Co-authored-by: Dmitrii Ovchinnikov <ovchinnikov.dmitrii@gmail.com> v2: added encoder reinitialisation v3: use AMF_SURFACE_UNKNOWN to int decoder(ctx->output_format before)
* avutil: add hwcontext_amf.Dmitrii Ovchinnikov2025-02-049-0/+718
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds hwcontext_amf, enabling a shared AMF context for encoders, decoders, and AMF-based filters, without copy to the host memory. Code also was tested in HandBrake. Benefits: - Optimizations for direct video memory access from CPU - Significant performance boost in full AMF pipelines with filters - Integration of GPU filters like VPP, Super Resolution, and Compression Artefact Removal(in future plans) - VCN power management control for decoders. - Ability to specify which VCN instance to use for decoding (like for encoder) - AMD will soon introduce full AMF API for multimedia accelerator MA35D - With AMF API, integration will be much easier: GPU and the accelerator will have the same API - including encoder, decoder, scaler, color converter, Windows and Linux. Learn more: https://www.amd.com/en/products/accelerators/alveo/ma35d.html Changes by versions: v2: Header file cleanup. v3: Removed an unnecessary class. v4: code cleanup and improved error handling v5: Fixes related to HandBrake integration. v6: Sequential filters error and memory leak have been fixed.

| | | | | | | | | | | | | | If there's a very large ISOBMFF box that needs to be skipped, it can cause an overflow for ctx->skip. There's already a safeguard to return quickly if ctx->skip > bufsize, so changing ctx->skip to int64_t will allow this to happen even if ctx->skip would overflow a signed int. Several other members are also changed to int64_t to avoid this problem in other possible scenarios.

* rtmpproto: Avoid rare crashes in the fail: codepath in rtmp_openMartin Storsjö2025-01-281-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running the cleanup in rtmp_close on failures in rtmp_open, we can in rare cases end up using rt->playpath, assuming that it is still set. The crash could happen if we hit the fail codepath in rtmp_open while publishing (rt->is_input == 0) with rt->state set to a value > STATE_FCPUBLISH. This would normally not happen while publishing; either we have an error (and rt->state <= STATE_FCPUBLISH) or we reach rt->state = STATE_PUBLISHING, and then we also return successfully from rtmp_open. The unexpected combination of states could happen if the server responds with e.g. "NetStream.Play.Stop" while expecting "NetStream.Publish.Start"; this sets rt->state to STATE_STOPPED, which also fulfills the condition "> STATE_FCPUBLISH". We don't need to free the rt->playpath/tcurl/flashver strings here; they're handled via AVOption, and thus are freed automatically when the protocol instance is freed (that's why they aren't freed manually within the rtmp_close function either). We also don't need to free the AVDictionary with options; it's owned by the caller. A smaller fix would be to just call rtmp_close before freeing the strings and dictionary, but as we don't need to free them at all, let's remove that redundant code.
