Using the Record Video function, game audio is also recorded (many props to those in the engineering team that made this possible, by the way). However, it defaults to 64kbps, which is pretty low quality. Now, video bitrate can be changed from its 5Mbps default using an ADB property, say to 20Mbps:
adb shell setprop debug.oculus.capture.bitrate 20000000
Is there anything like this for audio bitrate? If not, can we have such a property?
