Also, what about the C# video converter, is it Windows-only?
Technically C# can be used in linux via Mono. Also it will probably be redone in C/C++ to work with the encoders faster.

Would we be able to convert other type of formats such as h.263/4 or even Fraps? Or would we still need to use a software that supports Xvid conversion?
The library im using supports h.263/4 and a whole lot of others. As for Fraps, never even heard of it so No. Some level of conversion will be needed any way, because holding full color, audio interwoven data etc. on an nspire would be stupid and space consuming. So in some cases conversion will be more like data stripping.

would you like a dedicated space?
Sure, maybe when I actually have something to release.

Did I just read XVID on the TI-Nspire ? . . . =^.^=
It is still very very experimental but MIGHT actually work in witch case no other codecs would really be needed due to its supper performance. Its not really that hard because xvid is completely open source in C.

Can we decrease the framerate?
Yes, once i release the converter tool this will be as simple as adding one argument. It should be ready in a few days because im currently adding in actual codec support.

Have you seen any good news-worthy programs/events?  If so, PM me with an article to be included in the next issue of CGPN!

I should write one.  ;)
Yeah, sorry i didn't notice that. You are free to write whatever you like about it and or PM if you have any questions. Im currently tied up with some annoying XVID code, but ill be happy to help if needed.

This looks awesome deng4! What's the max length/size of videos it takes?
The frame count is saved as a 32bit integer so theoretically if you had enough memory internally or externally it can go on for hours without end. But, on an ordinary nspire 15mb is about the max which can store around 2.5 minutes. This number is assuming settings are at ~24fps interlaced, so that number can vary a little depending on quality.

First of all this is in not the same video player as apcalc's nPlayer. I made this one during the last week in an attempt to achieve much higher levels of compression then other calculator video players The current version uses intraframe deflate compression and interframe RLE based change compression. Also interlaced videos are supported for even more compression. Overall this allows for about 7 sec/MB, but i have even more compressed video in the works. To generate video files I made a C# converter (will include in next release) of full color gifs to my more compressed format automatically. Currently the player can maintain a constant set fps which can theoretically be [1,100]. Each frame takes about 10ms (5 interlaced) to render. I would really like to know what you guys think and I will add more improvements soon.
