Subject: [PATCH v0 0/3] Performance improvement of decoder

From: Jackson Lee <jackson.lee@...psnmedia.com>

The wave5 codec driver is a stateful encoder/decoder.
The following patches is for improving decoder performance. 

v4l2-compliance results:
========================

v4l2-compliance 1.28.1-5233, 64 bits, 64-bit time_t

Buffer ioctls:
                warn: v4l2-test-buffers.cpp(693): VIDIOC_CREATE_BUFS not supported
                warn: v4l2-test-buffers.cpp(693): VIDIOC_CREATE_BUFS not supported
        test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK
        test CREATE_BUFS maximum buffers: OK
        test VIDIOC_EXPBUF: OK
        test Requests: OK (Not Supported)

Total for wave5-dec device /dev/video0: 46, Succeeded: 46, Failed: 0, Warnings: 2 
Total for wave5-enc device /dev/video1: 46, Succeeded: 46, Failed: 0, Warnings: 0

Fluster test results:
=====================

Running test suite JCT-VC-HEVC_V1 with decoder GStreamer-H.265-V4L2-Gst1.0 Using 1 parallel job(s)
Ran 133/147 tests successfully               in 68.517 secs

(1 test fails because of not supporting to parse multi frames, 1 test fails because of a missing frame and slight corruption,
 2 tests fail because of sizes which are incompatible with the IP, 11 tests fail because of unsupported 10 bit format)

Running test suite JVT-AVC_V1 with decoder GStreamer-H.264-V4L2-Gst1.0 Using 1 parallel job(s)
Ran 78/135 tests successfully               in 35.015 secs

(57 fail because the hardware is unable to decode  MBAFF / FMO / Field / Extended profile streams.)
