* avfilter: add pad_cuda filterJorge Estrada12 days1-0/+24
| | | | | | | | | | | This patch adds the pad_cuda video filter. A filter similar to the existing pad filter but accelerated by CUDA. The filter shares the same options as the software pad filter. Example usage: ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i input.mp4 -vf "pad_cuda=w=iw+100:h=ih+100:x=-1:y=-1:color=red" out.mp4 Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* avfilter/vf_libplacebo: add `reset_sar` optionNiklas Haas2025-06-201-4/+8
| | | | | | | | | | This was requested by users of `vf_libplacebo`, to mirror the existing option on the other `vf_scale_*` family of filters. While we have `vf_normalize`, it was not as useful in the event that the content stretching was actually desired. Bridges an important usability gap between `vf_scale` and `vf_libplacebo` that made mixing and matching the filters needlessly difficult.

* avformat/whip: Add WHIP muxer support for subsecond latency streamingJack Lau2025-06-041-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 0. WHIP Version 3. 1. The WHIP muxer has been renamed and refined, with improved logging context and error messages for SSL, DTLS, and RTC. 2. Magic numbers have been replaced with macros and extracted to functions, and log levels have been altered for better clarity. 3. DTLS curve list has been updated, and SRTP profile names have been refined for FFmpeg and OpenSSL. 4. ICE STUN magic number has been refined, and RTP payload types have been updated based on Chrome's definition. 5. Fixed frame size has been refined to rtc->audio_par->frame_size, and h264_mp4toannexb is now used to convert MP4/ISOM to annexb. 6. OPUS timestamp issue has been addressed, and marker setting has been corrected after utilizing BSF. 7. DTLS handshake and ICE handling have been optimized for improved performance, with a single handshake timeout and server role to prevent ARQ. 8. Consolidated ICE request/response handling and DTLS handshake into a single function, and fixed OpenSSL build errors to work with Pion. 9. Merge TLS & DTLS implementation, shared BIO callbacks, read, write, print_ssl_error, openssl_init_ca_key_cert, init_bio_method function and shared same data structure 10. Modify configure that whip is enabled only dtls is enabled(just support openssl for now) to fix build error Co-authored-by: winlin <winlinvip@gmail.com> Co-authored-by: yangrtc <yangrtc@aliyun.com> Co-authored-by: cloudwebrtc <duanweiwei1982@gmail.com> Co-authored-by: Haibo Chen <495810242@qq.com> Co-authored-by: Steven Liu <lq@chinaffmpeg.org> Co-authored-by: Jun Zhao <barryjzhao@tencent.com> Signed-off-by: Jack Lau <jacklau1222@qq.com> Signed-off-by: Steven Liu <lq@chinaffmpeg.org>

* avutil/avassert: Add av_unreachable() and av_assume() macrosAndreas Rheinhardt2025-05-211-0/+3
| | | | | | | | | | | | | Useful to let the compiler and static analyzers know that something is unreachable without adding an av_assert (which would be either dead for the compiler or add runtime overhead) for this. The implementation used here enforces the use of a message to provide a reason why a particular code is supposed to be unreachable.

* fftools/graphprint: Add execution graph printingsoftworkz2025-05-151-0/+10
| | | | | | | | | | | | | | | | | | | | | The key benefits are: - Different to other graph printing methods, this is outputting: - all graphs with runtime state (including auto-inserted filters) - each graph with its inputs and outputs - all filters with their in- and output pads - all connections between all input- and output pads - for each connection: - the runtime-negotiated format and media type - the hw context - if video hw context, both: hw pixfmt + sw pixfmt - Output can either be printed to stdout or written to specified file - Output is machine-readable - Use the same output implementation as ffprobe, supporting multiple formats Signed-off-by: softworkz <softworkz@hotmail.com>

* ffmpeg: add per-stream input option drop_changedGyan Doshi2025-03-241-0/+6
| | | | | | | | | | | | | | This is a replacement in ffmpeg for the deprecated avcodec flag AV_CODEC_FLAG_DROPCHANGED. This option is meant to be used when the filtergraph should not be reinited upon input parameter changes as that leads to loss of state in the filtergraph potentially leading to broken or aborted output, e.g. inserting of silence with first_pts specified in aresample. Generally useful to avoid corrupted yet decodable packets in live streaming inputs. This option when enabled takes precedence over reinit_filters
