Termux automation

[miscounted]

I find this video player convenient for watching videos. I have already partially figured out how to open links in grayjay via am command, and would like to have grayjay automatically return to termux once (or some seconds after) the video is finished if the share intent had a specific flag inside the intent.

This would be helpful for figuring out new algorithms or generally taking control of what you watch on the your side of code.
Sure, addons may be a thing, but in my eyes this requires less effort and users may use any programming language of their choosing. Since android intents are open, you can even substitute termux for something else that supports making custom intent calls and is programmable.

So far I got the sharing part going on

am start -a android.intent.action.SEND -t "text/plain" -e android.intent.extra.TEXT "<url>"

I'm sure it can be improved, as I haven't figured out how to call com.futo.platformplayer specifically. Until then, I can use "always" in the share intent window to always pick grayjay.
