There is no use to CPU memory edges when decoding in hardware (arguably
libavcodec should be "enhanced" to not add them in that case).
This unbreaks VDPAU.

Some browsers, such as Firefox, are very picky about WebM streams needing to
start with a keyframe. To be able to handle this correctly when streaming,
the avformat mux needs to mark keyframe-containing blocks (or clusters, in
Matroska terminology) as such even after they have been muxed. The next patch
in the series will make httpd actually care about this flag.

Unfortunately, as avformat does not actually propagate this status, we need
to use some heuristics to figure out which blocks contain keyframes. The natural
thing to do would be to say that when we write a keyframe, the block that comes
back has to be a keyframe block, but the WebM/Matroska muxer thwarts this by
having its own internal buffering of clusters, flushing the _previous_ cluster
when we send it a keyframe. Thus, we need to explicitly send a flush (a NULL
packet) before the one that comes back when we mux a keyframe.

The previous value, 32 kB, causes formats like WebM to overflow
and split the blocks, which has negative consequences for streaming.
We're unlikely to have a memory crunch in this area, so increase it
to something generous.

This fills in the initial vlc_meta_t object with more of the fields
it knows about, ensuring fields that we can edit with taglib don't
show up in the 'Extra metadata' panel.

This places them in the same order as they appear in vlc_meta.h to
make it easier to see which ones are present and which ones are
missing.

vorbis_ParseComment() supports several different methods of

This propagates more of the data between a vlc_meta_t object and
the taglib object used to write out new metadata. This should
support everything except Setting, URL, NowPlaying, ArtworkURL, and
TrackID.

sys->first_pts is the time the stream started originally, but was
mistaken as the time of the stream was paused.

Now, it is assumed that pausing and resuming take approximately the
same time. This is usually true, and if it is not, there is no way for
either VLC or PulseAudio to know (since ALSA does not expose
pause/resume latency informations for the underlying devices).

In practice, this makes no real difference other than removing a bogus
warning about being late when resuming from pause.

Close #9291

Since libavcodec decoder doesn't expect matroska formatted wavpack anymore.

Some APE files can have a single packet duration of up to 30s
Is there even a hard limit in this format, or can packets be longer?

Previous gap limit was an arbitrary 22s, written in a way reminiscent of
the MPEG 90kHz clock, which does not make sense anymore since reference clock
in all our demuxers use our own 1MHz clock.

Also explicitely use CLOCK_FREQ

This enables direct rendering for H.264 software decoding.
