5d560d38de pixfmt: Add ARIB STD-B76 color transfer characteristic 
Adding hybrid log-gamma (https://en.wikipedia.org/wiki/Hybrid_Log-Gamma)
based on the standardization in ARIB STD-B67:
http://www.arib.or.jp/english/html/overview/doc/2-STD-B67v1_0.pdf

The choice of enum value of 18 is consistent with HEVC:
http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=10481

And also with latest proposal for color format in mkv:

90944ee3ab avconv: refactor selecting an encoder 
Fail immediately if automatic encoder selection failed. Always set the
stream_copy/encoding_needed flags in one place.

5e1840622c avconv: fix handling attachments in init_output_stream 
The current code assumes that encoding_needed is simply an inverse of
stream_copy, which is not true for manually attached files (for which
neither of those is true).

73c6ec6d65 avconv: create simple filtergraphs earlier 
We already have all the necessary information in open_output_file().
This makes the information about the stream/filtergraph mappings
available earlier.

58640fe89e h264: handle frame recovery in h264_field_start() 
This is a more appropriate place for this. H264Context.recovery_frame is
shared between frame threads, so modifying it where it is right now is
invalid.

e26c64148b h264: discard slices of redundant pictures right after parsing the slice header 
Going through the whole decoder initialization process for a slice we
are not going to decode is unnecessary and potentially dangerous.

6efc463858 h264: always set redundant_pic_count during slice header parsing 
It is always checked in the surrounding code, so this make sure we don't

b13fc1e344 h264: do not pass H264Context to h264_slice_header_parse() 
This should make it more clear that this function does not need any
decoder-global state other than the parameter sets.

996f13413b h264: fix warnings in fill_filter_caches_inter() 
The code does some weird casting to a 2-dimensional sub-array of
ref2frm. This is not necessary, since only one dimension is needed
there.

1cf2f3d334 h264_sei: drop an unnecessary h264dec.h include

70b1dcef2d h264: tighten the valid range for ref_frame_count 
This field (which the spec calls max_num_ref_frames) must be less than
or equal to MaxDpbFrames, which is at most 16.

f638b67e57 h264: move the parameter set definitions to a new header file 
The PS parsing code is independent from the decoder, so it makes more
sense for it to have its own separate header.

4e2f621248 svq3: stop using H264Picture 
The SVQ3 decoder has been decoupled from the H.264 decoder, so it can
now use its own data type.

Anton Khirnov
251cbb4400 h264: create a new header for common h264 definitions 
Move the NAL unit types into it. This will allow to stop including the
whole decoder-specific h264dec.h in some code that is unrelated to the
decoder and only needs some enum values.

9df889a5f1 h264: rename h264.[ch] to h264dec.[ch]

f651c6a259 h264: factor out setting frame properties / side data 
Right now this code is mixed with selecting the next output frame. Move
it to a separate function called from h264_field_start(), which is a
more appropriate place for this.

17e7c03e12 h264: only allow ending a field/starting a new one before finish_setup() 
Doing this after ff_thread_finish_setup() is called is invalid and can
conflict with reads from the other thread.

debca90863 h264: store {curr,max}_pic_num in the per-slice context 
While the value of those variables will be constant for the whole frame,
they are only used in two functions called from slice header decoding.
Moving them to the per-slice context allows us to make the H264Context
passed to slice_header_parse() constant.

f966498e43 h264: decode the poc values from the slice header into the per-slice context 
Copy them into the decoder-global context in field_start(). This avoids
modifying the decoder-global context during bitstream parsing.

54dd9b1cdd h264: set mb_aff_frame in frame_start() 
Avoid unnecessary modification of the decoder-global state in per-slice
code.

8d36932c8d h264: move the block starting a new field out of slice_header_parse() 
There is no bitstream parsing in that block and messing with
decoder-global state is not something that belongs into header parsing.

Nothing else in this function depends on the value of current_slice,
except for two validity checks. Those checks are also moved out of
slice_header_parse().

b25cd7540e h264: pass a H2645NAL to slice header decoding 
Replace the decoder-global nal_unit_type/nal_ref_idc variables with the
per-NAL ones. The decoder-global ones still cannot be removed because
they are used by hwaccels.

846a3e78a5 mov: Support prores with multiple stsd 
This function needs to return false, or data in the additional tables
will be skipped, and the decoder will not be able to decode frames
associated with them.

7672997004 mov: Implement support for multiple sample description tables 
Store data from each stsd in a separate extradata buffer, keep track of
the stsc index for read and seek operations, switch buffers when the
index differs. Decoder is notified with an AV_PKT_DATA_NEW_EXTRADATA
packet side data.

Since H264 supports this notification, and can be reset midstream, enable
this feature only for multiple avcC's. All other stsd types (such as
hvc1 and hev1) need decoder-side changes, so they are left disabled for
now.

This is implemented only in non-fragmented MOVs.
