I recently found out about the screenrecord feature of ADB on Android since API19.

If I try and execute this from Android Terminal Emulator on my device, I get the response from the device I would expect (identical to what I get on my CMD window when executing from Windows) but the file it creates does not work. The file is always ~3.3kb in size and VLC gives me the error:

VLC can't recognize the input's format: The format of 'file:///C:/Users/Jonny%20Wright/Downloads/videoo.mp4' cannot be detected. Have a look at the log for details.

(I have not checked the VLC log as from what has been happening it seems it is a problem with the recording of the video by the device as when executing from Windows it works fine.)

You need to run screenrecord as root, type su to switch to root (your phone needs to be rooted obviously)
