Yusuke Nakamura 45a811b512 mov: fix composition timestamps on movie fragments. 
This fixes, for instance, the case that there is a track that has some samples with composition time offset and has a track run without sample-composition-time-offsets-present.

Alex Converse 869303bebd wmavoice: Use proper size in memeset(). 
sizeof(array_functrion_argument) gives the size of the pointer type not
the size of the array to which it points.

Ronald S. Bultje 7d2e03afc8 vc1: make overlap filter for I-frames bit-exact. 2011-05-04 07:40:53 -04:00
Ronald S. Bultje 5c9f147e05 vc1dec: use s->start/end_mb_y instead of passing them as function args. 2011-05-04 07:40:02 -04:00
Ronald S. Bultje 18b6a69ce9 Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." 
This reverts commit f8bed30d8b. The reason
for this is that the overlap filter, which runs after IDCT, should run
on unclamped values, and thus IDCT and put_pixels() cannot be merged if
we want to attempt to be bitexact.

Uoti Urpala 0bd433a916 asfdec: fix assert failure on invalid files 
Add an extra size validity check in asf_read_frame_header(). Without
this asf->packet_size_left may become negative, which triggers an
assertion failure later.

Diego Biurrun ad1862d64a ALPHA: Replace sized int_fast integer types with plain int/unsigned. 
int/unsigned is the natural memory access type for CPUs, using sized types
for temporary variables, counters and similar just increases code size and
can possibly cause a slowdown.

Justin Ruggles 177fed4e9b ac3enc: do not store a bandwidth code for each channel. 
Although AC-3 allows it, it's not very useful. The encoder uses the same code
for all full-bandwidth channels.

Justin Ruggles a1d0f511fc ac3enc: remove bandwidth reduction as fallback for bit allocation failure. 
It was only needed at low bitrates, which now already use a low bandwidth, so
the bandwidth reduction is no longer needed.
