* [FFmpeg-devel] [PATCH v1 1/4] lavc/vaapi_encode_h265: Add P frame to GPB frame support for hevc_vaapi

From: Linjie Fu <linjie.fu@intel.com>

Use GPB frames to replace regular P frames if backend driver does not
support it.

- GPB:
    Generalized P and B picture. P frames replaced by B frames with
    forward-predict only, L0 == L1. Normal B frames still have 2
    different ref_lists and allow bi-prediction

From: Mark Thompson <sw@jkqxz.net>

The block size can be dependent on the profile and entrypoint selected.
It defaults to 16x16, with codecs able to override this choice with their
own function.

From: Mark Thompson <sw@jkqxz.net>

max_14bit_constraint_flag should be set if the bit depth is not greater than
14 (currently always true).

one_picture_only_flag should not be set because we don't support the still
picture profiles.

general_profile_compatibility_flag should be set according to general_profile_idc
instead of bit depth.
