* avcodec/g729dec: Use 64bit and clip in scalar productMichael Niedermayer2019-11-25
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | c0c79461967 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 c0c79461967 to fix the issue.
