30475c95ba lavc/h264dsp: R-V V 8-bit h264_idct_add16 
While this *tends* to be faster than plain C, the performance numbers
are all over the place, presuambly due to the conditional character of
the main loop.

Some additional micro-optimisations should be feasible after the
underlying h264_idct_add and h264_idct_dc_add functions are also
implemented. Then it will no longer be necesseray to stricly abide by
the C ABI.

cd9ceaef22 avutil/hwcontext_videotoolbox: Set CVBuffer CGColorSpace 
In addition to the other properties, try to obtain the right
CGColorSpace and set it as well, else it could lead to a CVBuffer
tagged as BT.2020 but with a CGColorSpace indicating BT.709.

Therefore it is essential for consistency to set a colorspace
according to the other values, or if none can be obtained (for example
because the other values are all unspecified) unset it as well.

necessary to properly delete undefined attachments, else we can

e14cdf9990 hlsenc: Calculate the average and actual maximum bitrate of segments 
Previously, the bitrate advertised in the master playlist would only
be based on the nominal values in either AVCodecParameters bit_rate,
or via AVCPBProperties max_bitrate. On top of this, a
fudge factor of 10% is added, to account for container overhead.

Neither of these bitrates may be known, and if the encoder is
running in VBR mode, there is no such value to be known. And
the container overhead may be more or less than the given
constant factor of 10%.

Instead, calculate the maximum bitrate per segment based on
what actually gets output from the muxer, and average bitrate
across all segments.

When muxing of the file finishes, update the master playlist
with these values, exposing both the maximum (which previously
was a guesstimate based on the nominal values) via
EXT-X-STREAM-INF BANDWIDTH, and the average via
EXT-X-STREAM-INF AVERAGE-BANDWIDTH.

This makes it possible to use the hlsenc muxer with VBR
encodes, for VOD style muxing.

9246cca7f7 hlsenc: When not using HLS_SINGLE_FILE, set vs->size to range_length 
This matches what is done in the corresponding case for
HLS_SINGLE_FILE.

Normally, vs->size is already initialized correctly - but when
writing the initial segment, with mp4 files, vs->size has been set
to the size of the init segment, while range_length contains the
real size of the first segment.
