When decoding coefficients, detect whether the block is DC-only, and take advantage of this knowledge to perform DC-only inverse transform. This is achieved by: - first, changing the 108x4 element modulo_three_table into a 108 element table (kind of base4), and accessing each value using mask and shifts. - then, checking low bits for 0 (as they represent the presence of higher frequency coefficients) Also provide x86 SIMD code for the DC-only inverse transform.

This is different than a normal get_bits() over read because decode_audio_specific_config() creates its own GetBitContext. Fixes Bug 170.

This indicates that the actual frame size is based on the buf_size passed to avcodec_encode_audio().

Since packets all contain only a single block, the generic seek function can be used while still maintaining block-accuracy.

The WAVE demuxer returns packets with many blocks per frame, which needs to be parsed into single blocks. This has a side-effect of fixing the timestamps.

Under certain conditions pictures could be released before they were returned with frame-threading. Broken mv computation in the upcoming rv34 frame-threading patch was caused by this. To prevent contexts from running out of available pictures the loop releasing "unused" pictures has to be run for B frames too.

Fixes Libav Bug 195. This doesn't make the code handle sample rate or upsample/downsample change properly but this is still a good sanity check. Based on change by Michael Niedermayer. Signed-off-by:

The duration of the first packet was being calculated incorrectly, leading to an incorrect timestamp offset.

If the creation time is stored in the file as a zero, the mov demuxer skips exporting the creation time. Currently, files muxed without a creation time get demuxed with a Jan 1st 1970 creation timestamp. Signed-off-by:
