This reverts commit be583c6f.

This was not approved, and was accidentally pushed. I'm very sorry.

This is the matrix that will be used for up/downmixing.

The AVCodecContext.get_format callback is not only used for pixel format
negotiation with the API user, but also for hwaccel init. For the
latter, it's required that some codec parameters, in particular the
codec profile, are set when the callback is invoked.

This patch removes a get_format invocation where this is not guaranteed.
The codec parameters, including the profile, are really set further
below. (The same code path that sets the profile also calls get_format
properly too.)

This just happened to work by coincidence in most cases. For example, if
the API user just copied or reused the AVStream's AVCodecContext when
decoding, the profile would be set properly. But in some cases it
fails., such as with the sample WolfensteinTwitch.mp4 on the samples
server.

Remove the redundant get_format call. Apparently it serves no purpose
anymore, although it is possible that this was different at the time it
was added in commit ffd77f94.

This fixes hwaccel usage for API users which do not set the profile
when setting up the AVCodecContext (which is allowed).

This makes AAC init threadsafe.

Without EXT-X-MAP support we miss the first bytes of some streams.

These streams worked by luck before byte-ranged segment support was added in
da7759b3

Fixes ticket #4797.

Commit ad701326 ("avformat/hls: open playlists immediately when
AVDISCARD_ALL is dropped") inadvertently caused first_packet to never be
cleared, causing select_cur_seq_no() to not use the specific code for
live streams.

In practice this means that when the user selects a different audio
track during live stream (i.e. non-VOD) playback, there may be some
additional delay as the code might select an incorrect segment at first,
and we have to wait for video to catch audio (if too late segment was
selected) or to download more following audio segments (if too early
segment was selected).

Fix that by restoring the zeroing of first_packet.

This allows hwaccels to access the bitstream header information.
