Many samples will fail because "Output buffer size is too small."

Many samples will fail because "Output buffer size is too small."

Do not use rlelen for buffer size in init_get_bits, it is
only the size of the data for the first field.
Since it is not reliable, just use the size of the whole buffer.
Additional comments add removal of unused rlelen variable by
Reimar Döffinger.

This means it uses full brightness range and brightness
increasing instead of decreasing with index of non-opaque
color.

Based on patch by Alexandre Colucci [alexandre elgato com]

This makes the avi demuxer create packets with proper pos values
with the file from ticket #140.

This currently only occurrs in vsrc_buffer in case of mid-stream
size/format change.

Fix trac issue #124.

* qatar/master:
  ALPHA: Replace sized int_fast integer types with plain int/unsigned.
Duplicate  DPX image encoder
Duplicate  DPX decoder: read sample aspect ratio
Duplciate  DPX decoder: add buffer size checks.
  ac3enc: clip large coefficient values and negative exponents rather than using av_assert2().
  ac3enc: do not store a bandwidth code for each channel.
  ac3enc: remove bandwidth reduction as fallback for bit allocation failure.
  ac3enc: merge compute_exp_strategy_ch() into compute_exp_strategy()
  ac3enc: return error if frame+exponent bits are too large instead of using av_assert2().
  ac3enc: differentiate between current block and reference block in bit_alloc()
  ac3enc: simplify exponent_init() by calculating exponent_group_tab[] based on exponent group sizes.
  ac3enc: simplify stereo rematrixing decision options
Include both URLs:  Update URL to fate samples

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.

av_assert2().

Although AC-3 allows it, it's not very useful. The encoder uses the same code
for all full-bandwidth channels.

It was only needed at low bitrates, which now already use a low bandwidth, so
the bandwidth reduction is no longer needed.

av_assert2().

This can occur in some very rare cases with low bitrates.

on exponent group sizes.

They use now code identical to the AAC decoder.
The AC3 decoder previously did not check the data_size and
the dca decoder checked against and set wrong values for float.

Improve consistency with libavcodec.

This breaks libavfilter API/ABI.

The non-sequential 2.1.0 -> 2.4.0 bump is due to the mess previously
done with the lavfi minor number.

The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.

This is similar to what was done with pkt_pts. This simplifies the
operation of extracting the pos information from the AVPacket, and
allows further simplifications.

flac.o implies vorbis_data.o because of flac channel layout.

This possibly fixes issue2679
