Adb screenrecord command does not work Android 5x emulators

[mikedawson]

A bug on the Android emulator results in 0 byte output files:

This seems to apply to both the AOSP emulator and the emulator with Google APIs. AdbScreenRecord gets a 0 byte video file which won't play.

This should probably show an error message in place of the video when a non-supported device is detected.

It might be possible to implement a workaround by using the a screen recorder on the host OS itself (e.g. recordmydesktop) to get the video.

e.g.

xwininfo -name "device name"
recordmydesktop --windowid ...
