    No, for that you'll need more specialized DSP hardware.

    The most likely solution for you would be to get an inexpensive iPod that can do video output and find some information on the Internet for making your own remote control for it using a serial I/O device. A Prop could then produce the remote control sequences needed. I don't have any links to that sort of information, but I've seen it before on the internet.

    Those are specially crafted files, not out-of-the-box avis (well avi is not a format, just a container). There are some ARM processors with SMID extensions that are able to do what you (may) want. Especially if full color and better than 128x96 (or so) resolution is needed.
    if what you saw on those videos is enough, them the propeller may be a candidate.

    Thanks for the page mpark [noparse]:D[/noparse]

    nemesiswes, those vids that I did, were converted from AVI's so yes can "technically be any avi" ( pre-conversion ) to a format that I used for the PropGFX add-on for Hybrid, as the Hybrid has SD built onto the board, ( for retreival of the video from SD card ) so yes it can be done, and plays to composite AV, with mono audio.
    but if you want decent quality ( as that image is 128x96 pixel resolution and propeller colours. ) you'd be better off going for an iPod or ARM if you want to do the programming yourself.

    It's really down to what quality you're happy with like Ale said [noparse]:D[/noparse]

    There was also deepfry. Fits the "any" part of your request.

    Will the Prop2 be able to do this in full color?

    I bet you could play uncompressed AVI at TV resolution from Flash using a bunch of external ICs...

    I'm working on a 320x240 TFT driven by a Prop that I hope will able to play full screen video with audio from SD.

    But driving TV or VGA is more difficult because you have to have the right timing...

    Cool Rayman, which TFT? got any pics/vids? keep us posted on that [noparse]:D[/noparse]

    I bet PropII will be able to do a decent codec too [noparse]:D[/noparse]

    It's a run-of-the-mill 2.4" TFT LCD with ILI9325 controller.

    PropII should do MP3 decoding, but I doubt it could do video decoding. But, we'll see...

    If you're looking for something small that can play videos, perhaps you need a BeagleBoard.

    600Mhz ARM Cortex A8, 430Mhz TMS320C64+ DSP, and 3D graphics accelerator. All on a 3" square board that takes <2Watts for $150

    Run's Linux, has DVI-D output, and USB. I would still connect one if it's UARTs to a Propeller for external control interfaces, but...

    I'm working on making a Laptop out of mine.
