The decoder hardcodes that audio is stream_id = 1 so it does not
currently work with more or less than 1 video stream at st=0

The G729 reference decoder clips after each individual operation and keeps track if overflow
occurred (in the fixed point implementation), this here is
simpler and faster but not 1:1 the same what the reference does.
Non fuzzed samples which trigger any such overflow are welcome, so
the need and impact of different clipping solutions can be evaluated.

As is the decoder will never stop, it will cause an infinite loop. The RFC seems only
to speak of non empty packets so endlessly generating noise from the last empty flush
packets seems wrong.

The threshold is chosen so that the worse frames would together not take
excessive time.
A better solution is welcome!

If mkv_write_trailer() is not called, the cached audio packet might
leak; so unref it in mkv_deinit().

c0c7946196 unintentianally changed the initialization flow of the
decoder: It caused the capture buffers to be initialized on
v4l2_m2m.c:180 in v4l2_configure_contexts(). This breaks h264 decoding
on the Odroid XU4 (RPI4 was not affected).
This commit postpones capture buffer initialization
as before c0c7946196 to fix the issue.
