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

Running test suite JCT-VC-HEVC_V1 with decoder GStreamer-H.265-V4L2-Gst1.0
Using 3 parallel job(s)
Ran 133/147 tests successfully               in 41.629 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 3 parallel job(s)
Ran 78/135 tests successfully               in 44.578 secs

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

Seek test
=====================
1. gst-play-1.0 seek.264
2. this will use waylandsink since gst-play-1.0 uses playbin.
   if you don't want to hook up display,
   you can run gst-play-1.0 seek.264 --videosink=fakevideosink instead
3. Let pipeline run for 2-3 seconds
4. press SPACE key to pause
5. press 0 to reset
press SPACE to start again

gst-play-1.0 seek.264 --videosink=fakevideosink
Press 'k' to see a list of keyboard shortcuts.

Change since v0:
===================
* For [PATCH v1 2/7] media: chips-media: wave5: Improve performance of decoder
 - separates the previous patch to a few patches

* For [PATCH v1 3/7] media: chips-media: wave5: Fix not to be closed
 - separated from the previous patch of performance improvement of
   decoder

* For [PATCH v1 4/7] media: chips-media: wave5: Use spinlock whenever state is changed
 - separated from the previous patch of performance improvement of
   decoder

* For [PATCH v1 5/7] media: chips-media: wave5: Fix not to free resources normally when
    instance was destroyed
 - separated from the previous patch of performance improvement of
   decoder

* For [PATCH v1 7/7] media: chips-media: wave5: Fix SError of kernel panic when closed
 - separated from the previous patch of performance improvement of
   decoder
