We changed priority to favor “Android USB cable support” over “h264 encoding”.
Android USB cable support is already working.
Android USB cable support will become available publicly within the next few weeks.
h264 encoding might not even be continued after this (too many quirks, performance gain too small for regular users).
Instead we are currently evaluating WebRTC network communication protocol for larger performance gain.
WebRTC software can implicitly use h264 encoding anyway (by software as well as hardware-accelerated).
