V4L2Decoder: use map to associate block IDs to V4L2 buffers

Block IDs can be arbitrarily large, but we only have a limited number of
V4L2 buffers. Keep an association between the block IDs received from
VideoFramePool and a V4L2 buffer slot to use with them instead of
assuming that block IDs can be used as valid V4L2 buffer indices.

Bug: 161323057
Test: arc.VideoDecodeAccel.h264_vm fully passes on Kukui.

V4L2-based Codec2 Component Implementation

Description of Sub-folders

  • accel/ Core V4L2 API and codec utilities, ported from Chromium project.

  • common/ Common helper classes for both components/ and store/.

  • components/ The C2Component implementations based on V4L2 API.

  • store/ The implementation of C2ComponentStore. It is used for creating all the C2Components implemented at components/ folder.

  • service/ The Codec2's V4L2 IComponentStore service. The service initiates the component store implemented at store/ folder, and registers it as the default service.
