Audio is unsync recording in high resolution in slow devices

[pablogeek]

I'm using a Samsung Galaxy tab A 8" 2019.
I set resolution to 1600x900 and seems that the first video frames of the recording are like in slow motion. I have even see if async encoder could fix it, but no it seems it has something related with how OpenGL renders it. Is there anyway to fix this?

Here there is a interesting discussion about this issue. https://stackoverflow.com/questions/39171949/android-mediacodec-eglswapbuffer-blocking-gpu-in-asynchronous-mode

Thanks!
