Changes in 7.1

Raw Captions with Time (RCWT) closed caption demuxer
LC3/LC3plus decoding/encoding using external library liblc3
ffmpeg CLI filtergraph chaining
LC3/LC3plus demuxer and muxer
pad_vaapi, drawbox_vaapi filters

vf_scale2ref deprecated
qsv_params option added for QSV encoders

xHE-AAC decoder
removed DEC Alpha DSP and support code
VVC encoding support via libvvenc
perlin video source
D3D12VA HEVC encoder
Cropping metadata parsing and writing in Matroska and MP4/MOV de/muxers
Intel QSV-accelerated VVC decoding
MediaCodec AAC/AMR-NB/AMR-WB/MP3 decoding
YUV colorspace negotiation for codecs and filters, obsoleting the YUVJ pixel format
Vulkan H.264 encoder
Vulkan H.265 encoder
stream specifiers in fftools can now match by stream disposition
LCEVC enhancement data exporting in H.26x and MP4/ISOBMFF
LCEVC filter
MV-HEVC decoding
minor stream specifier syntax changes: - when matching by metadata (:m:<key>:<val>), the colon character in keys or values now has to be backslash-escaped - in optional maps (-map ....?) with a metadata-matching stream specifier, the value has to be separated from the question mark by a colon, i.e. -map ....:m:<key>:<val>:? (otherwise it would be ambiguous whether the question mark is a part of <val> or not) - multiple stream types in a single specifier (e.g. :s:s:0) now cause an error, as such a specifier makes no sense
