Music video

[desertfish]

Inspired by Tony's work on this I wanted to create my own music video "creation pipeline" and playback program, mostly as an exercise to see what's involved in realizing something like this.

Source a/v conversion heavy lifting is done by ffmpeg + a python script that converts the resulting frame data into the correct vera vram format. Source code available on request.

I simply had to use one of my favorite songs and video clips from the 80's for this: Take On Me from A-ha.

The video runs at 160*128 pixels at 15 fps and the sound is fairly high quality at 27Khz. But it's mono, because the sd-card isn't fast enough to support decent quality stereo sound next to the video stream. I think it's theoretically possible given the 180-200 kb/sec data transfer speed limit of a decent sdcard, but it just doesn't sync right with the way the current implementation works (reading video and audio blocks from 2 different files independently - it is difficult to sync them up properly).
The playback speed of the song is changed by a factor of 0.992 because this is the factor of the VGA refresh rate v.s. precise 60 FPS as to sync the audio and video up again otherwise they would desync gradually.

Not trying to one up. Thought mine with code could be useful

Desertfish and I corresponded over this one quite a bit.

Would've been hilarious to "Rick roll" us.
