Eric Schwartz released a tribute to the Amiga called "Still Alive" a few months ago on YouTube. There's also an MP4 version of it, but so far, there was no Amiga native playback even though the animation itself is not very demanding (320x200 in 4 colours). The main problem was sync'ing the video with the music -- especially when the frame rate of the video is not exactly 50 Hz or 60 Hz. Latter also needed a playback routine of the original mp3, with less CPU demand (otherwise only 68060th would be able to play it back).
This is an Amiga and MorphOS compatible playback with ECS/AGA/P96/CGX support. The audio has been converted from 44 KHz 16 Bit stereo to 22 KHz 16 Bit mono with ADPCM encoding as a compromise. A 68020+ should be enough, but this has not been tested.
The playback needs AHI, but otherwise should find a suitable screen mode itself.
The only difference to the version shipped with the Deneb USB board is that under MorphOS it opens a 16 bit screen as somehow otherwise the rendering is not correct.
Enjoy and send your feedback to Eric Schwartz ;-)
