txd: Use the TextureDSP module for decoding
...
Using the internal DXTC routines brings support for non multiple of 4
textures. A new test is added to cover this feature. Hashes differ
since the decoding algorithm is different, though no visual changes
have been spotted.

mp3: enable packed main_data decoding in MP4
...
14496-3 suggests packing main_data of MP3 that is usually scattered
into multiple frames due to bit reservoir.
However, after packing main_data into a access unit, bitrate index
in the MPEG audio frame header doesn't match with actual frame size.
In order to accept this, this patch removes unnecessary frame size
checking on mp3 decoder.
Also, mov demuxer was changed to use MP3 parser only on special cases
(QT MOV with specific sample description) to avoid re-packetizing.

lavc: Clarify the behaviour of dimension and format context fields
...
The AVCodecContext width, height, coded_width, coded_height and format
are used mainly as decoding hints and they get internally overwritten
during the data parsing stage.
Do not assume they match the last AVFrame provided by
avcodec_decode_video2 and assimilated functions since multi-threading
and other frame reordering might make those values to refer to frames
that will be outputted in the future.

Since decoder couldn't properly map 4 back channels, decoding failed

The decoder assigns channels using default channel configuration
for 5.1ch when it parses an ADTS frame header using consecutive
channel ids.
When a PCE comes, it reassigns channels using PCE configuration
using directly the ids provided. They can be arbitrary.
Always use consecutive channel ids to avoid decoding glitches due
spurious reconfigurations due the channel ids mismatch between the
two otherwise-identical channel maps.

Personally, I need the decoder to back out if get_format() returns no
usable pixel format. This didn't work because the error code was not
propagated down the call chain. This in turn happened because the
variable declaration removed in this patch shadowed the variable, whose
value is returned at the end of the function. Consequently, failures of
decode_nal_unit() were ignored in this place.

dca_parser: Extend DTS core sync word and fix existing check

The previous version checked for 14-bit streams and did not properly
work across buffer boundaries.
Use the 64-bit parser state to make extended sync word detection work
across buffer boundary and check the extended sync word for 16-bit LE
and BE core streams to reduce probability of alias sync detection.

quickdraw: Switch to greedy parsing
...
Quickdraw packs data as a series of codes that the application is supposed
to handle, but it does not define any order in which they might appear.
Since it's unfeasible to support *all* opcodes defined by the spec,
only handle well-known blocks containing video data and ignore any unknown
or unsupported ones.
Move palette loading and rle decoding to separate functions to resue them
in other blocks and drop format initialization in init since it can
support more formats than pal8.
Validate width and height.

That function currently does two things -- reinitializing the DSP

The former more appropriately belongs in h264_slice_header_init(), while
the latter only really makes sense in decode_slice_header().
The third call to ff_h264_set_parameter_from_sps(), done immediately
after parsing a new SPS, appears to serve no useful purpose, so it is
just dropped.

Currently, the DPB is initialized in alloc_tables() and uninitialized in

Since we want the init/uninit to happen exactly once per the context
lifetime, init_context()/free_context() are the proper place for this
code.

h264: reset the private data in init_thread_copy()

The generic code copies the main context's private data to all the

pointers that are or will become invalid.
Since everything we actually need will be copied later in
update_thread_context(), it's safest to zero the private data in
init_thread_copy(), so it works the same way as init for the main
context.

They are always constructed anew when needed, so there is no need to
reset them explicitly.

error_resilience: move the MECmpContext initialization into ER code
...
Currently, it needs to be initialized by the ER caller (which is
currently either a mpegvideo decoder or h264dec). However, since none of
those decoders use MECmpContext for anything except ER, it makes more
sense to handle it purely inside ER.

mpegvideo_enc: Draw edges on input for non-multiple of 16 resolutions
...
This improves motion estimation and avoids using uninitialized data
for resolutions that aren't a multiple of 16.
Prior to d2a25c40
, the edges used to be initialized so that encoding
was deterministic, but after that commit it started using uninitialized
data (for non multiple of 16 resolutions).

imgutils: create misc functions for dealing with buffers
...
Move the lavc/imgconvert functions and rename them as follows:
avpicture_get_size -> av_image_get_buffer_size()
avpicture_fill -> av_image_fill_arrays()
avpicture_layout -> av_image_copy_to_buffer()
The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).
The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).
A redundant check has been dropped from av_image_fill_arrays().
