Answer 1

The screenrecord feature doesn't work in the AOSP emulator, because the software AVC encoder doesn't support the necessary features. As noted in this bug , the screenrecord binary will be removed from future emulator distributions to avoid confusion.

I don't expect support to be added in the near future, as this requires a bunch of work in the codec.
