Attachment: Bug 1918620 - android video recording (WIP)

This doesn't actually work right now, because screenrecord in our images
doesn't have
https://android.googlesource.com/platform/frameworks/av/+/b88917cc3dcdf1cb58862729e7f7096e6476a55e
and so is limited to 3 minutes. So we'd have to either upgrade it somehow, or
record 3 minutes at a time then merge the files, e.g. adb shell "while true; do screenrecord --output-format=h264 -; done" | ffmpeg -i - screencast.mp4.

can we build it and push to into the image maybe? rather than having to update the android version

Maybe, but I don't know how to do that.

As an update, this is working(ish) when using an android 15 image on the emulator. However either the screenrecord or the adb process gets killed after a few minutes, and I haven't yet figured out why.
