Dear all


Our customer plays a video on HTML by using WebView of AndroidKK4.4.2.


Display: HDMI output

OS: AndroidKK4.4.2 FSL BSP
Package: AndroidKK4.4.2_Extended Feature Packages(android_kk4.4.2_1.0.0-ga_omxplayer_source)
Patchs: 0001-Fix-the-video-only-stream-can-t-play-issue.patch

Issue_01_video_performance.pdf: outline
Issue_01_index9.mp4/Issue_01_index10.mp4: captured videos
Issue_01_sample: test samples

They test Video Playback in this environment.

When two plane is composed, frame rates decrease.
- WebView is overlaid on the picture.
- The frame rates decrease from 25fps to 12fps


When it is not overlaid, this problem does not happen.

When Chromium is used, this problem does not happen.
(In this case, even if it is overlaid, the problem does not occur.)


It seems that 2D acceleration doesn't work well when WebView is overlaid on the picture.


They investigate this problem.
Which cord should they refer to?

May I have advice?


Best Regards
