The screen of Huawei P10 on the web is black after using minicap

[XiaLeon]

Hi, I was using minicap to test Huawei device P10 whose model is VTR-AL00. In most cases I found the screen on the web turns into black. I added some logs in my code and I found the size of first 4 bytes is only 8787. According to my testing result, the normal size is more than 30,000 and the screen on the web shows properly. Then I checked the logs on the device and I found some ERRORs: 07-05 10:58:59.989 E/HWComposer( 727): getLayerReleaseFence: Invalid display 07-05 10:58:59.989 E/HWComposer( 727): getPresentFence failed for invalid display -1 07-05 10:58:59.989 E/HWComposer( 727): getLayerReleaseFence: Invalid display 07-05 10:58:59.989 E/HWComposer( 727): getPresentFence failed for invalid display -1 07-05 10:58:59.989 E/HWComposer( 727): getLayerReleaseFence: Invalid display 07-05 10:58:59.989 E/HWComposer( 727): getPresentFence failed for invalid display -1 07-05 10:58:59.995 I/dubaid ( 781): [AbnormalityRoutine.cpp] checkCpuAbnormality# 2000:/data/local/tmp/minicap:0.029:69411:9431#10905:com.huawei.termctrl.utk:0.017:39948:5540

Are these logs related to this issue? If it's convenient for you, can you please get a Huawei P10 and test it? I'd really appreciate it. Thanks so much!

I’ll take a look if you donate a device. Otherwise it’s very unlikely it’ll happen.

@sorccu Where's the address so I can send it to you? I'm in China.

Huawei P20 is the same. @XiaLeon Has this issue been resolved?

[XiaLeon]

@yinpc Not yet. I added some logs in the source code of minicap and found that the bytes size returned by socket is also 8787. So I suppose this must have something to do with android. Because I saw that minicap called android API. What's your detailed phenomenon ?
