Pinetime is an open smart watch provided by our friends in pine64. [tt-392] want to prove that the hardware can play full dynamic music video and is correct to a certain extent. When you watch the video below, you should notice that monochrome animation maintains a healthy frame rate, which is all hard work. Without any modification, the video will play at a speed of about 8 frames per second.
To convert MP4, you need to decompose it into images to remove sound. Next, load them into a Linux only video processor that looks for pixel clusters that need to be changed and ignores static pixels. “Relevant pixel selection” will load some data on the display and improve FPS, because you won’t waste time reminding it that black pixel blocks should remain intact. Finally, the process compresses everything to put it into the on-board memory of the watch. Even a few minutes of black-and-white photos can take hours to compile.
You need to enter the inside of the watch, so I hope you have a developer kit or don’t mind opening the seal. Who are we kidding? You’re not here. The video resides in a flash memory chip, and you must transmit one block at a time. Bad apples require 14, so you may want to practice on a shorter video. Finally, the core memory needs some updates to play correctly. Now you can sit down and… Watch.
Pine64 didn’t start well in single board computers, but they won our trust in soldering iron and Google free Linux phones.
