Drop dependency on Java/server

[luke-jr]

Is there any reason this can't just use the native screenrecord and input CLI tools?

For input:

• performance Why your adb shell cmd execute so fast? #231

For video:

• screenrecord is limited to 180 seconds
• buffering issues with adb shell stdout (a frame could be written but stay in buffer)
• reduced frame latency Reduce latency by 1 frame #646
• correctly handle rotation
• correctly handle resize without adding unwanted black borders (when one dimension is not multiple of 8)

For info, I used the output of screenrecord for the initial PoC, killing it and restarting it on every rotation and every 3 minutes (which by the way produced a corrupted stream), it worked but was very hacky.
