It's a hell of a drug.

I wish to record a few hours of video from the front camera of my Android 8.0 device and hopefully keep only the relevant/visible/audible portions.

Tl;DR: Looking for a reliable Android 8.0 front camera monitoring program with automatic trimming of static audio/visual cap.

Tomorrow I'm having a ketamine infusion procedure and I'd like to be able to experience it as a sober person afterward doing the postop. Basically they take a hueg (approaching 1 liter) dosing syringe, fill it with saline and a certain dose of ketamine, and have a syringe pushing machine push it into an IV over the course of a couple hours, while sitting in a comfy chair (and a fanatical devotion to the Pope) and monitored regularly by the medical staff.

My only experiences with ketamine have been this ROA, and my thought process has definitely been... altered, with little transition time between 'yes that slight feeling seems to be it possibly kicking in' to 'fully gorked and on approach for Moon Unit 42069The dissociative class is also notorious sort of like benzodiazapenes for impinging on your memory while under,r the influence. The substance does have a certain recreational mystique around it, and I'm wondering what I'm doing while otherwise noodling around on my tablet and having Constant Moments Of Ultimate Revelatory Thought in silence (they say I remain calm, don't talk much, and once was caught closely inspecting the automatic vitals monitor display; also one time I apparently got in a fight with my tablet's bumper cover, took it off, and threw it to the floor to find later; the instigator was never duscovered)

Tomorrow will be a higher dose than before, so I firgure postanalysis would be helpful. If there is a simple, reliable program for recording everything the front camera sees while also automatically stripping out things 6motionlly staring at the wall that's was also a simple off the shelf program that would be great. If the right thing doesn't pop up by tomorrow then that's okay too, I could get it set up for next time.

I don't think video analysis is yet at the point where off the shelf software can detect the interesting parts of your recording from the visuals. (A neutral network could be trained but doing that would require heaps of tagged training data, the creation of which would be more effort than manually searching your footage).

But you can do this with audio. There are programs that can detect and timestamp, or discard, audio sequences where nothing is happening (ie just background noise). You can also do it manually fairly easily by opening the wave form in eg Audacity and looking for peaks vs sections where the wave form doesn't change for ages. Then you can go to the timestamps in the video that match the interesting audio.

If you are recording audio from your phone and it is very close to your body, with very high microphone sensitivity, body moments should produce enough rustling to show up. You'd have to experiment with settings and positioning in advance.
