18156b53f9 hevc: do not pass an entire HEVCContext into export_stream_params()

650060dfb6 hevc_parser: parse and export some stream parameters

That loop does the actual full decoding, so 'parse' can be misleading.

d82e1adc20 hevc: move splitting the packet into NALUs into a separate function 
This function is independent of the decoding context, so we'll be able

ae05b48655 hevc: eliminate the second call to hls_nal_unit() 
Also, make hls_nal_unit() work only on the provided NAL unit, without
requiring a whole decoding context.

This will allow splitting this code for reuse by the parser.

d7bebe4805 hevc: skip invalid/ignored NALUs when splitting the packet 
There is no need to wait until actually decoding the NALU. This will

86eee85dad bytestream2: set the reader to the end when reading more than available 
This prevents possible infinite loops with the calling code along the
lines of while (bytestream2_get_bytes_left()) { ... }, where the reader

1410eeb6ea imc: Use correct position for flcoeffs2 calculation 
flcoeffs2[pos] should be the log2 of flcoeffs1[pos].
flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf,
causing problems further down.

This seems to have been copied from imc_decode_level_coefficients in
commit 4eb4bb3 without updating the position.

02b7c63087 h261: Signal freeze picture release for intra frames 
Freeze picture release should be set to 1 when we're responding to a
fast update request. For simplicity we set it for all intra frames,
including those that starts a GOP.

Fixes issue where Tandberg MXP1700 does not recover from packet loss
state since it's waiting for the freeze picture relase indication.

dc1de0b958 h261: Set 'still image mode off' in picture header 
Ref H.261 recommendation section 4.2.1.3, setting the still image flag

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.

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.

ee62b364be h264: eliminate ff_h264_set_parameter_from_sps() 
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.

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.

87e85a133f aac: Relax reserved_bit validation 
Although the specification mandates this bit to zero, it may happen
that software tools incorrectly flip it to one, invalidating a possibly
valid stream.

Relax this restriction, by failing only when AV_EF_BITSTREAM is set.
This behaviour is similar to aac decoders in Firefox and Quicktime.
