Session data (cookies, user-agent) is not being sent on payload requests with
encrypted HLS streams This causes services like Akamai to give a 403 forbidden
when requesting the TS files, because they expect the same cookies
and user-agent on all requests
The muxer will write at least the number of bytes requested and possibly
up to 3 bytes more. This is because the muxer writes 32-bit integers
and the format requires 4-byte alignment anyway.

Allows a user to control the amount, if any, of padding they want added

All samples in the wild are RGB565/555 and we are already

Improved DVB subtitles encoder to generate AVPacket.data in the same
format as generates MPEGTS demuxer + DVB subtitles parser. So now single
format of DVB subtitles data is used across all the components of FFmpeg:
only subtitles payload WITHOUT 0x20 0x00 bytes at the beginning and 0xFF
trailing byte.
Improved MPEGTS muxer to support format of DVB subtitles in
AVPacket.data described above: while muxing we add two bytes 0x20 0x00 to
the beginning of and 0xFF to the end of DVB subtitles payload.

If the audio changes from 9eac7c4 were merged as they were, this
would cause scripts with both video+audio to fail with a lot of
audio decoding errors (the video would be fine). Scripts with
only one of either video or audio were unaffected. Additionally,
the av_packet changes in general caused seeking to break.
Using av_packet_from_data allows video+audio scripts to work as

AVFormatContext is still used for logging, if available.
Chapter parsing is the only non-logging functionality that actually
needs AVFormatContext, and AFAICS it should be modified to write the
data to ID3v2ExtraMeta first, from where it can be implanted to
AVFormatContext by a separate function (like it is done with
read_apic() and ff_id3v2_parse_apic()). That is outside the scope of
