91767360d8 a64multienc: Do not entangle coded_frame
This change (and the following ones of the same kind) is mainly to
simplify wrapping this section with an #if FF_API block later on.

No functional changes are applied, the fields of the context coded_frame
fields are directly initialized, instead of keeping a reference to the
coded_frame itself.

a344e5d094 x86: bswapdsp: Don't treat 32-bit integers as 64-bit
The upper halves are not guaranteed to be zero in x86-64.

Also use `test` instead of `and` when the result isn't used for anything other
than as a branch condition, this allows some register moves to be eliminated.

dc1de0b958 h261: Set 'still image mode off' in picture header
Ref H.261 recommendation section 4.2.1.3, setting the still image flag
to 1 disables still image mode. Some decoders require this in order to
decode the bitstream as normal video.

Fixes H.261 calls to Cisco E20.

Also, reserved (aka spare) bits should be set to 1 unless specified
otherwise.

6ec688e1bc 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.

9af7e8045e 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.

FDK AAC encoder outputs SCE(front)+CPE(front)+CPE(back)+CPE(back) on

Since decoder couldn't properly map 4 back channels, decoding failed
unless -request_channel_layout 0x8000000000000000 has been specified.
Now we treat first CPE(back) as CPE(side) on channel mapping.

0289f81241 aac: Correctly map multichannel ADTS AAC with non-zero channel_config + PCE
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.

3efe0393e4 hevc: make avcodec_decode_video2() fail if get_format() fails
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.

11f024ef0a h264: move freeing the escaped RBSP buffer to free_context()
It does not logically belong in free_tables(), since it's not allocated

ee62b364be h264: eliminate ff_h264_set_parameter_from_sps()
That function currently does two things -- reinitializing the DSP
contexts and setting low_delay based on the SPS values.

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.

Also, drop now unneeded H264Context.cur_chroma_format_idc.

a6cd154463 h264: move the DPB init/uninit to init_context()/free_context()
Currently, the DPB is initialized in alloc_tables() and uninitialized in
free_tables(), but those functions manage frame size-dependent
variables, so DPB management does not logically belong in there.

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.

bd737b5178 h264: reset the private data in init_thread_copy()
The generic code copies the main context's private data to all the
others. However that is quite dangerous, as it might end up copying some
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.
