Receive transcode key from PlexPy when paused. Send key to sub-script to wait for X time then check if still paused. If paused kill.

create_wait_kill.py

kill_transcode function from https://gist.github.com/Hellowlol/ee47b6534410b1880e19

        {transcode_key}


create_wait_kill.py creates a new file with the transcode_key (sub_script) as it's name.
PlexPy will timeout kill_trans_pause_wait.py after 30 seconds (default) but sub_script.py will continue.
sub_script will check if the transcode stream is still pause or if playing as restarted.
If playback is restarted then sub_script will stop and delete itself.
If stream remains paused then it will be killed and sub_script will stop and delete itself.

Set TIMEOUT to max time before killing stream
Set INTERVAL to how often you want to check the stream status

@csy7550 Looks like a Plex update made this obsolete. Here is a similar script that uses Plex's new kill stream.
