Zhao Zhili 20c5f4d835 avutil/frame: fix remove_side_data
remove_side_data is supposed to remove a single instance by design.
Since new_side_data() doesn't forbid add multiple instances of the
same type, remove_side_data should deal with that.

Guo, Yejun 1ef4828276 avutil: add ROI (Region Of Interest) data struct and bump version
The encoders such as libx264 support different QPs offset for different MBs,
it makes possible for ROI-based encoding. It makes sense to add support
within ffmpeg to generate/accept ROI infos and pass into encoders.

Typical usage: After AVFrame is decoded, a ffmpeg filter or user's code
generates ROI info for that frame, and the encoder finally does the
ROI-based encoding.

The ROI info is maintained as side data of AVFrame.

wm4 4b86ac27a0 lavu/frame: add QP side data
This adds a way for an API user to transfer QP data and metadata without
having to keep the reference to AVFrame, and without having to
explicitly care about QP APIs. It might also provide a way to finally
remove the deprecated QP related fields. In the end, the QP table should
be handled in a very similar way to e.g. AV_FRAME_DATA_MOTION_VECTORS.

There are two side data types, because I didn't care about having to
repack the QP data so the table and the metadata are in a single
AVBufferRef. Otherwise it would have either required a copy on decoding
(extra slowdown for something as obscure as the QP data), or would have
required making intrusive changes to the codecs which support export of
this data.

The new side data types are added under deprecation guards, because I
don't intend to change the status of the QP export as being deprecated
(as it was before this patch too).

wm4 554bc4eea8 avcodec, avutil, avformat: remove AVOption requirement for some fields
Allow all struct fields to be accessed directly, as long as they're
public.

Before this change, many fields were "public", but could be accessed via
AVOption only. This meant they were effectively not public, but were
present for documentation purposes, which was incredibly confusing at
best.

wm4 e3af49b14b AVFrame: add an opaque_ref field
This is an extended version of the AVFrame.opaque field, which can be
used to attach arbitrary user information to an AVFrame.

The usefulness of the opaque field is rather limited, because it can
store only up to 32 bits of information (or 64 bit on 64 bit systems).
It's not possible to set this field to a memory allocation, because
there is no way to deallocate it correctly.

The opaque_ref field circumvents this by letting the user set an
AVBuffer, which makes the user data refcounted.

Anton Khirnov 32c8359093 lavc: export the timestamps when decoding in AVFrame.pts
Currently it's exported as AVFrame.pkt_pts, which is also the only use
for that field. The reason it is done like this is that lavc used to
export various codec-specific "timing" information in AVFrame.pts, which
is not done anymore.

Since it is confusing to the callers to have a separate field which is
used only for decoder timestamps and nothing else, deprecate pkt_pts and
use just AVFrame.pts everywhere.

Neil Birkbeck d91718107c libavutil: add mastering display metadata sidedata
Adding mastering display metadata struct to avutil. The mastering display metadata contains information
about the mastering display color volume (SMPTE 2086:2014).

This info comes from HEVC in the SEI_TYPE_MASTERING_DISPLAY_INFO and is soon to be included in MKV:
https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&index=sZyfPTM-QY69P-0omfOIiTN622o
so it is similar to SEI FPA / stereo_mode in MKV and as such this patch follows how AVStereo3D is implemented.

I'll add support to HEVC in a follow-up (and MKV when spec is approved).
