I built https://ffprompt.ryanseddon.com using the chrome ai (Gemini nano). Allows you to do ffmpeg operations on videos using natural language all client side.
In my home state of Victoria Australia the government had a program to give out these powerpal[1] units for free that could measure your usage in realtime using the flashing led on our smart meters, we also require all energy grid operators (the people who own the poles and wires) to have an energy portal where users can get near realtime data to the nearest 30mins, soon to be 5 with some new legislation.
The former most people have no idea about but the powerpal has been a smashing success for consumers to understand what is using energy.
I've got an oven and induction cooktop freestanding unit[1] that has big chunky knobs to change the induction power levels. Would never bother with gas again.
I did something similar using filter_complex to create a 14x14 grid showing 196 days of earth full disc shots for my earthin24 Twitter bot. It's truly impressive what ffmpeg can do https://ryanseddon.com/javascript/an-earth-mosaic/
I couldn't even use it on my phone, I think the viewport meta set to device-width makes it load zoomed in and the interaction with the content makes it impossible to zoom out.
The ontouchstart issue can be avoided by using the ontouchmove/end to check of the user is scrolling. Infact zepto.js has a custom event called "tap" which does exactly that.
