We believe it’s quite outstanding to see a Stellaris Launchpad playing back video as well as Audio at the exact same time with a respectable frame rate. It should be a prominent time of year for these jobs since we just saw one more video playback hack yesterday. however for this job [Vinod] had a great deal less horsepower to work with.
He’s utilizing a 320×240 screen which we ourselves have tried out with this board. It’s plenty quick sufficient to push picture data in parallel, however if you’re searching for full movement video and audio we would have told you difficult luck. [Vinod’s] math shows that it is possible with a bit of data hacking. very first off, because the source data is widescreen he gets away with only composing to a 320×140 set of pixels at 25 fps. The audio is pushed at 22,400 bytes per second. This leaves him extremely few cycles to really do anything between frames. So he encoded the clip as a raw file, interlacing the video as well as audio info to ensure that the data can be checked out as a single stream. From the demo after the break it looks as well as seems fantastic!
