Sreerenj Balachandran [Thu, 10 Aug 2017 01:36:13 +0000 (18:36 -0700)]
FEI: plugin: Add vaapih264feienc element

A new FEI based encoder element for h264 is added: vaapih264feienc

FEI is a an extension to VA-API which is providing low level
advanced control over different stages of encoding.
Extending vaapih264enc with fei support is possible, but it will
make the code too much complicated and will be difficult
to debug. So adding the new encoder element, but keeping
the rank as 0 , vaapih264enc will stay as the primary
encoder for normal use cases.

The vaaih264feienc is mainly useful for customers who want to play
with MotionVectors and Macroblock Predictions. Also user can
do one stage of encoding(eg: only the Motion Vector Calculation)
in software and offload trasformation/entroy-coding etc to
Hardware (which is what PAK module is doing) using FEI element.

vaapih264feienc can work in  different modes using fei-mode properoty

eg: gst-launch-1.0 videotestsrc ! vaapih264feienc fei-mode=ENC+PAK ! filesink location=sample.264

Important Note: ENC only mode won't produce any encoded data which is expected.
But ENC alwys requires the output of PAK in order to do the inter-prediction
over reconstructed frames.
Similary PAK mode alway requires MV and MBCode as input, so unless there is an
upstream element providing those buffers, PAK only won't work as expected.

In a nutshell, ENC_PAK and the ENC+PAK modes are the only options we can verify
with vaapih264feienc. But ideally, EN+PAK mode verification is enough to make sure
that ENC and PAK are working as expected since ENC+PAK mode always invoke ENC and PAK
separately in vaapih264feienc.

libs: decoder: h264: decode SVC base layer only

Drops non-base NALs when the base-only property is set to TRUE.
This modifies the behavior for MVC streams with base-only too: All the
non-base units are dropped before they are decoded instead of dropping
the non-base frames.

The relevant part from the H264 spec is:
> Decoders that conform to one or more of the profiles specified in
Annex A rather than the profiles specified in Annexes G or H shall
ignore (remove from the bitstream and discard) the contents of all NAL
units with nal_unit_type equal to 14, 15, or 20.

To eliminate side effects from the offending units:
- PPS's with a broken seq_parameter_set_id (referring to dropped subset
SPS's) are ignored.
- The NAL parsing is skipped and their flags are set to
GST_VAAPI_DECODER_UNIT_FLAG_SKIP.
- Prefix units are not stored in prev_pi. Otherwise, parse_slice() would
use them even if they are flagged to be skipped. Subset SPS's and slice
extension units are not stored there either.
