Android 9, edm1 imx6 quad (wandboard), WebView slow video playing about cookers HOT 4 CLOSED

Tested same here, but could you check this webview is better or not:
webview:

local video player:

Due to IMX6 limitation, the only way is increase CMA and galcore size such as following command on u-boot prompt:
setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24 video=mxcfb1:off vmalloc=128M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=512M galcore.contiguousSize=134217728 loop.max_part=7 quiet

That is for video one setting (CMA=512MB, galcore size=128MB), but I think you should be still feel a bit slow...

Webview browser has some limitation for HW acceleration although it does support GPU, and NXP seems no any improvement since Android 4, I have other customers face this challenge before, they usually have some workarounds:

1. reduce the video resolution to 720P (actually if your default resolution is 720P, it's okay)
2. web server send a request about shell command to playback video using local player when click play video button
3. change browser such as firefox or chromium, but I remember just improve a little bit performance.

You can try to increase CMA size to 512MB and try again.

Hello,

Thanks for your answer. We will investigate whether we can use a 720p resolution or not.
In the meantime, I just realize that the default resolution of the build is on 720p and not 1080p why is that ?

How can I get the 1080p resolution by default on the android 9 build ?

Thanks.

You'll know why default resolution is 720P when you changed (not smoothly...):

1. quick way in u-boot prompt (for test):
   setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:off vmalloc=128M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=512M galcore.contiguousSize=134217728 loop.max_part=7 quiet

2. modify the source code in BoardConfig.mk
   Modify KERNEL_CMDLINE from video=mxcfb0:dev=hdmi,1280x720M@60 to video=mxcfb0:dev=hdmi,1920x1080M@60

Thanks!

ok, thanks for the answer, I close the issue.
