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.

c0c79461 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 c0c79461 to fix the issue. Signed-off-by:
