They are then interleaved with the audio to produce the final format. It also processes each frame for differential changes, reducing the size to fall within the available bandwidth. ImageMagick takes it from there to convert the PPM files to a bitmap format. FFMPEG is used on a modern computer to process the source video by separating the audio into an 8-bit 11040Hz file, and it generates several PPM files with the proper video frame rate. In the most recent thread post (at the time of writing) shares the methods used to get this running. This is the second iteration of his player, and can be seen after the break playing a promo video for CoCoFEST 2011 where he’ll show it off in person. The decades-old hardware performs quite well considering the limited resource he had to work with. wrote a digital video player for the Tandy Color Computer (aka TRS-80). Posted in classic hacks Tagged CoCo, color computer, trs-80 Tandy Color Computer (CoCo3) Color Video Playback Sadly, is judge for the Retrochallenge this time around, so he’ll have to settle for earning a Hackaday merit badge. It’s a clever little hack to increase the color palette of the CoCo, and in our opinion should be in the running for winning this season’s Retrochallenge. during the vertical blanking interval), he could display 44 colors on the CoCo. figured out if he switched the color pallets every 1/60th of a second (i.e. These color palettes are extremely limiting, and usually switching between these modes produces a lot of flicker. There are several graphics modes available to CoCo programmers, including a high-resolution black and white mode, and two four-color modes using red, green, blue, and yellow or buff, cyan, magenta, and orange.

The TRS-80 Color Computer uses a Motorola 6847 video display generator to produce color graphics on its display. By default, the CoCo could only display 8 colors on the screen at a time, but figured out a way to increase the number of colors displayed using a very simple trick that surprisingly isn’t found in original CoCo games. Note that by default, errors thrown by ImageMagick will not reach you, apart from a nonzero return code.As a relic of the early 80s, the TRS-80 Color Computer couldn’t display very many colors.

I'll leave this post for future reference.Īs for the specifics when setting up this environment on a cluster, you'll have to translate each step for the specific needs for your server I guess. It's not rocket science, but still somewhat of a hassle to set up the first time around. This old post popped up while I was struggling to get some matplotlib animations exported as an animated gif.
