Normally the decoder should not run out of input buffers as it is fed with
packetized data and for each input block a picture shall be generated. In rare
situations the decoder seems to fail internally and does stop generating
pictures. In this case the input buffers are not released either. If this
happens the whole pipeline stalls and vlc buffers input data until system runs
out of memory. To avoid this error case force the decoder to flush its port
if it runs out of input buffers. This causes a short image distortion but the
decoder won't block anymore.

The mutex held within mmal_pictures is used to lock access of mmal
picture/buffer pools between vlc main thread and mmal callback threads. This
is only required to be locked per pool and not globally for all mmal modules.
Thus using a global mutex caused a slight performance hit when using mmal vout
and deinterlace simultaneously which operate on independent picture pools. Now
the pool owner provides the mutex handle when allocating the pictures, so
that independent locking can be used.

If buffers were discarded because of wrong size or type a mmal buffer header
would be leaked each time.

Instead of assuming that p_pixels[0] points to the mmal opaque handle retrieve
it from the picture_sys structure. Using p_pixels for the pointer was broken
due to vlc core copying p_pixels only for formats with actual data.

The Wayland background thread dereferences said variable, but is started
before the value is written there. Occasionally the thread would win
the race and segfault in wl_display_get_fd.

Ulgy resampler produces really noisy output with some samples,
it is way better with libsamplerate.

Use global pmt es count, as there's no multiple pmt

Because the no-trust-pcr thing isn't a real fix.

A variable cannot be inherited if it is not a configuration item.
Note this only avoids generating an error; VBI cannot work without the
plugin anyway.

Since (*) we can't tell if the sample is v0 follows the ISO
spec or comes from qt and then means uncompressed,
we can't agregate samples reliably.

* our muxer removed qt brand from files.
