Sounds pretty nice, does it support sound and all 65536 colors?There's no sound, but I think it supports full 16-bit color.
The busy box (or hourglass) is pretty annoying, but it is side effect of the Bfile_ReadFile_OS() function :-(There's a bit of empty space below the video. Would it be possible to move the video down, so that the busy indicator will appear above the video? It would help a bit, even though it doesn't give us a way to get rid of the indicator.
There's a bit of empty space below the video. Would it be possible to move the video down, so that the busy indicator will appear above the video? It would help a bit, even though it doesn't give us a way to get rid of the indicator.That would be very easy, but I would like to try to get rid of the busy box completely first :-)
Yes, it is full color video, no sound yet. It is slow, video has about 5 fps, but running about 2 fps - this is not problem of the video size, but calculator speed. I need to overclock it (now it is running on original speed).That's a good start, but I'd aim for at least ~10-15fps. Sound support would also be nice once it is figured out. Very cool stuff though! ^^ /me goes to try it out.

So there are few things to be solved yet :-)
Are going to port Ich Will ?I can :-)
You shouldn't have to overclock the Prizm to get a high framerate. At 58 Mhz a framerate of over 30 hz should be possible. What method are you using to draw the video. A slowdown will occur if you use pixel on commands instead of using the VRAM as a buffer. Also if you did any compression that would contribute to the slow down.
With the OS routines yes, but you can copy data to the VRAM faster than the OS can draw the screen. Just like for example with the PC game Half Life 2 most modern computers can get framerates near 200 fps even though most screens are limited to 60 hz.You shouldn't have to overclock the Prizm to get a high framerate.

A framerate of 20Hz is the maximum I would expect with the OS screendraw routines.
Are going to port Ich Will ?Enjoy it. Be sure to store it in the calculator as demo.mjp

How large would the file size become if JPEG isn't used? Maybe we could try some other kind of compression... I don't know what one would fit, though.Screen has 384 x 216 x 2 B,I use 1/2 images (192*108*2) => 41472B. The jpeg compression makes them around 3.2 KB
The color depth could also be reduced, from 16 to 8 bit.That's a possibility but I think that should be done on a frame by frame or segment of frames basis. As in there shouldn't be a single palette for the entire video but instead each frame or segment of frames should define a new one. You could even go as far to define an 8 bit palette for each frame then use 8 bit DXT1 compression for that frame. I'm also thinking it would be a good idea to interlace the video to increase speed while cutting size in half.
Other formats we could try are PNG but I'm unfamiliar with how long it takes to decompress compared to JPEG.PNG might not optimize well. If I recall correctly, PNG is good for simple drawings and graphics, while JPEG is suitable for images with lots of details (such as photos).
I'm also thinking it would be a good idea to interlace the video to increase speed while cutting size in half.Wouldn't interlacing look odd on a screen like this, considering that it's running at a low amount of fps? TVs can get away with it, but they have a refresh rate of 60Hz/50Hz.
Is the rar file supposed to be able to sent to the calculator as a rar, or should only the raw file be sent?Please, extract the rar and put the raw file in the calculator. I rared it to save bandwidth (and I would probably also touch the 7MB limit set on this server)
The frame rate looks great! :) Is the video supposed to be in grayscale, or is this something that was added for compression?Both:-) The video is in gray-scale (16 colors) to reduce video size.
Maybe RLE could be used for compression? It's popular on older calculators since they only have 2/4 colors. Using RLE with 16-bit color won't really work, but maybe it's good enough for 4-bit?The frame rate looks great! :) Is the video supposed to be in grayscale, or is this something that was added for compression?Both:-) The video is in gray-scale (16 colors) to reduce video size.

any instructions how to port a video?I would love to get instructions to port a video.
I don't think any video converter/importer were ever released yet.Yes, the player is experimental SW, I was trying different image/video formats and I created video file manually (extract frames from video, batch conversion + resize in irfan_view + dirty written program to put the frames together).
I may be interested.im interested too
I may be interested.You may download it at my page http://martin.poupe.org/casio/
hello, i try create a video using JPG filesYes, this is what I meant.
im in this step:
compression level 60 (use irfan_view - batch mode)
here is i can change compression level?
Could this be ported to FX-9860GII?I wrote another player (also with sound) for 9860G earlier, see http://ourl.ca/9205/219057 or
I checked those posts and page and it was not for the 9860GII as he asked, but rather the 9860 SD ???There are 3 types of 9860 as I know:
Hello,Martin, you might be better explain the steps 5 and 6 of SCVP conversion process?
I do not have any automated tool, I did following:
1. take a video and convert it (by autoGK) to have width 128 pixels.
2. extract images from the video (I used IV_Player.exe from Irfan view's plugins directory)
3. by irfan view - crop all images to have height 64 pixels (they had 80), decrease color depth to 2 (use Floyd-Steinberg dithering) and save as raw - use batch mode, images should have 1 byte per pixels -> 8KB per image
4. "compress" the images so they have 1 bit per pixel, the highest bit of the first byte is top left pixel (1KB per image)
5. negate it (on the calc 0 means white, 1 means black; opposite as on PC).
6. append all images together -> done
What kind of movies does it play, and does it need an SD card?it play special converted movies, and the app needs SD Card for save the video (video file is too big for non SD models) ...
Oh ok because if it's compatible with 9860G, then why does it require a SD card? The 9860G doesn't have an SD card slot...I checked those posts and page and it was not for the 9860GII as he asked, but rather the 9860 SD ???There are 3 types of 9860 as I know:
1. old 9860G ( + 9860G SD), this is the model on which I wrote the player and everything should work :-)
2. 9860 G II - very similar to old 9860G, has back-light and newer OS (which was possible to flash to the old 9860G and what I already did)
There should also everything work.
3. 9860 G II Power graphic 2 (I am not sure with the name), with CPU from Prizm. This is different HW, but because I released the source code, owner can use my sources, remove the sound part (which is platform specific) and use only silent video player. It should work I hope.
Oh ok because if it's compatible with 9860G, then why does it require a SD card? The 9860G doesn't have an SD card slot...the internal memory of the calculator does not have space for videos (for exemple, The demonstration video is 10 mb and it is small ...).... need to use the SD card to save it
Yeah but what I mean is if it requires SD, then why MPoupe says it's compatible on the 9860G in the first place, even though the 9860G lacks SD card support? Or is english language barrier the issue? ???OK, so the SD card presence (or non presence) is the issue :-)

I'm sorry to be a bother, but I'm a huge newbie to this type of thing, with minimal programming experience, although I hope to learn soon and go onto a computer science major.

I thought the PRIZM does not have an SD card slot. How will that work out?
This is too frustrating! I still don't know how to extract the frames!you can use this tool -> http://www.dvdvideosoft.com/guides/free-video-to-jpg-converter.htm
just use ffmpeg, like i suggested. it's simple. download and extract this (http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-git-6cb2085-win32-static.7z)cool, ffmpeg is good ;)
open the folder you just extracted and drag your wmv file into the "bin" folder. then hold shift and right click on the bin folder. select Open Command Windows Here. run this command:
ffmpeg -i <video_name>.wmv %d.jpg
and you're done :)
EDIT: modified because there is a way to open a folder in command prompt
ffmpeg -i video.flv -s 192x96 -r 11 %4d.jpgHow do I compile it for my Prizm? do I Open it in command prompt?frames compile guide -> http://ourl.ca/12057;msg=229626

'g++' is not recognized as an internal or external command,
operable program or batch file.It saystry use my compiled streamer.exeCode: [Select]'g++' is not recognized as an internal or external command,

What do I do to fix it?
How can I make it faster? Its pretty slow.Its faster, It takes about 15 seconds per 1000 frames
It is really slow compared to the real video. Are you sure there isn't a way to make it faster?Ahhh the video... You have compressed the frames in level 60?
How do you do that?There are many ways...
Can you do it in photoshop?No :( Photoshop doesnt have batch compression functions
Oh. How about I send the video download to you?No problem. Host the video in mediafire and give me the link
It is really slow compared to the real video. Are you sure there isn't a way to make it faster?Yes, the jpeg based player (CGPlayer2) is very slow, it runs about 2 fps.
The chinese MP4 producers use use formats AMV and MTV (more info about this formats here -> http://en.wikipedia.org/wiki/Chinese_MP4/MTV_Player)Interesting.
the processor of these mp4 video players is much weaker than that of the prizm
one decoder in google code (http://code.google.com/p/amv-codec-tools/)
what do you think?
You mean the grayscale for TI-8x+?.pgm is grayscale raster image format
Edit: Oh. You mean RAW?
How do you make them all grayscale and .pgm?
Good. I will need this. The .mjp on the cgplayer-simu is really fast..... O.O :crazy: *.*Nice job :-)
@MPoupe, how many FPS we can get in cgplayer 2 (jpg based) with overclock?With 150% overclock I would expect 3 fps :-)
Also MPoupe, would it be possible to make sure the video quality doesn't become too high or even remain as low as possible? ...What particular action do you mean I should do?
Make videos compressed enough to destroy the image quality as much as possible to make any text impossible to read, but still look watchable. Example below (another idea is reducing resolution to 84x48 then scaling the videos back up):Also MPoupe, would it be possible to make sure the video quality doesn't become too high or even remain as low as possible? ...What particular action do you mean I should do?

Example below (another idea is reducing resolution to 84x48 then scaling the videos back up):Unfortunately I do not have monopoly to create video. Anyone can create video and I cannot unrelease already released cfgplayer2.
Ok, well currently the quality isn't very high anyway, so I don't think it should be a problem. I was just talking about if you ever discovered a way to have even higher quality at high speed or something.OK, this would be easy ;-)
Some time ago, Martin Poupe released to the public their video player (http://martin.poupe.org/casio/cgplayer/index.html) for casio prizm.Good job !
However, he did not release any tool to convert videos (only some instructions), they had to be converted using the command line (http://ourl.ca/12057/283750), what was difficult for normal prizm users.
I've been working to create an easy way to convert videos, and I come heretoday(some time ago) to release this conversion tools.
Pc running windows (doesnt work on linux)
Not even with WINE?1 linux user reported me in my old site, that did not work with wine, however you can test it with wine and say if it worked or not.
cgplayer 3 only supports Black and white, is more faster, i think you can expect 12fps. I recommend this version!The raw based cgplayer (cgplayer3) supports 16 levels of gray. See screenshot here: http://martin.poupe.org/casio/cgplayer/7.jpg
