why flash screen while using screenrecord?

giszxl · ‎02-09-2018

my device is imx6q. If Multiple screenrecord at the same time, the device screen is flash，as shown in the appendix below。The screen is flash while surfaceflinger has two or more virtualdisplaysurface. I found the second virtualdisplaysurface hwcId=-12. Have anyone ever met the same problem and what is the root cause?

Hello,

Can you please tell me which Android version are you using and if you are using our Sabresd board?

Best Regards,

Diego.

Hello, the Android version is 7.1.1 with Sabresd board.

diegoadrian · ‎02-27-2018

Hello,

Is there a possibility that you can upgrade to our newer Android version (7.1.2)?

Some errors were fixed in that version, probably the error that you are facing was fixed.

Best regards,

Diego.

Hello,

Thanks for your reply. I can not upgrade to Android 7.1.1. Can you tell me what is the root cause? Is it a mistake about surfaceflinger or a mistake in the hwcomposer hardware device?

Best regards.

diegoadrian · ‎03-07-2018

Hello,

Let me see if I can reproduce your error. However, can you please tell me if you are using our demo image, or is an Android image made by yourself using our BSP.

Best Regards,

Diego.
