545f721b44 avfilter/vf_colordetect: add new color range detection filter
This filter can detect various properties about the image, including
whether or not there are out-of-range values, or whether the input appears
to use straight or premultiplied alpha.

Of course, these can only be heuristics, with "undetermined" as the base
case. While we can definitely prove the existence of full range or
straight alpha colors, we can never infer the opposite.

ad0a44028d avfilter: add pad_cuda filter
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

7039a37e35 avfilter/vf_libplacebo: add reset_sar option
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.

167e343bbe avformat/whip: Add WHIP muxer support for subsecond latency streaming
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

004cc60f0e avutil/avassert: Add av_unreachable() and av_assume() macros
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.

45926bc09a fftools/graphprint: Add execution graph printing
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
