956a54129d vaapi_h264: Set max_num_ref_frames to 1 when not using B frames 2016-09-28 22:54:11 +01:00

086e4b58b5 vaapi_encode: Sync to input surface rather than output 
While outwardly bizarre, this change makes the behaviour consistent
with other VAAPI encoders which sync to the encode /input/ picture in
order to wait for /output/ from the encoder.  It is not harmful on
i965 (because synchronisation already happens in vaRenderPicture(),
so it has no effect there), and it allows the encoder to work on
mesa/gallium which assumes this behaviour.

892bbbcdc1 vaapi_encode: Check packed header capabilities 
This improves behaviour with drivers which do not support packed
headers, such as AMD VCE on mesa/gallium.

80a5d05108 vaapi_encode: Refactor initialisation 
This allows better checking of capabilities and will make it easier
to add more functionality later.

It also commonises some duplicated code around rate control setup
and adds more comments explaining the internals.

6755eb5b21 mss12: validate display dimensions 
The code currently reads the coded dimensions from the extradata, but
expects the display dimensions to be set by the caller, and does not
check that they are compatible (i.e. that the displayed size is smaller
than the coded size).

Make sure that when the display dimensions are set, they are also valid.
Fixes possible invalid memory access.

4a9bab3db0 h264: fix decoding multiple fields per packet with slice threads 
Since we only know whether a NAL unit corresponds to a new field after
parsing the slice header, this requires reorganizing the calls to slice
parsing, per-slice/field/frame init and actual decoding.

In the previous code, the function for slice header decoding also
immediately started a new field/frame as necessary, so any slices
already queued for decoding would no longer be decodable.

After this patch, we first parse the slice header, and if we determine
that a new field needs to be started we decode all the queued slices.

f450cc7bc5 h264: eliminate decode_postinit() 
This function's purpose is not very well defined. Currently it does two
(only marginally related) things: selecting the next output frame and
calling ff_thread_finish_setup() for frame threading. The first of those
more properly belongs under field_start(), while the second can be
called directly from decode_nal_units().

17c99b6158 h2645_parse: handle embedded Annex B NAL units in size prefixed NAL units 
Fixes a regression in ca2f19b9cc with some mov/mp4 files. The files have
several NAL units in the supposed single NAL unit after the size field.
Annex B start code prefixes are used to separate them. The first NAL unit
is correctly parsed but the buffer does not point to the next size field.
Instead semi random data (it seems to be the rbsp_stop_one_bit and the
start code prefix) is then parsed as length and will exceed the
remaining length of the buffer.

Patch based on the code in h264's decode_nal_units() and a similar
patch by Hendrik Leppkes in FFmpeg (a9bb4cf87d).

a8cbe5a0cc h264_ps: export actual height in MBs as SPS.mb_height 
Currently, SPS.mb_height is actually what the spec calls
PicHeightInMapUnits, which is half the frame height when interlacing is
allowed. Calling this 'mb_height' is quite confusing, and there are at
least two associated bugs where this field is treated as the actual
frame height - in the h264 parser and in the code computing maximum
reordering buffer size for a given level.

Fix those issues (and avoid possible future ones) by exporting the real
frame height in this field.

ff_put_vp8_{epel,bilin}{4,8,16}_h[246]v[246]_armv6().

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.

This is a more appropriate place for it.

e85f6f7f8d lavc: allow using AVCodecContext.hw_frames_ctx for decoding 
For now it will only be used by the default get_buffer2 callback for
allocating hw frames.

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:

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
see a value from an old slice.
