Nvid is a video player for the Nspire. It is not the first such project, but it is unique in that it uses vp8 video. This allows long videos to be stored with a relatively small file size and good quality, although it results in somewhat slow playback.

Nvid supports both the Nspire CX, in full color, and the Touchpad/Clickpad in grayscale.

One example video is included, sintel.ivf.tns. To create your own videos, drag any video onto wrapper.bat in the "converter" folder. This creates a file called output.ivf.tns that can be transferred to the calculator.

Nvid does not have a file browser, so you need a version of ndless that supports file association. Run nvid.tns once to install the file association. After that, you should be able to open an ivf file and have it play.

The compression is lossy. It plays movies that are about 1.5 megabytes per minute of video, compared to 4 for nspire movie player. The quality is also better.

Yes, although the player doesn't actually use the Webm container.

Sorry if I was unclear:

• The VP8 codec is compressed lossily (ie, after decoding the result is not exactly the same as the original)
• Nspire Movie Player also uses lossy compression (its format is a zip of jpegs, and jpegs are lossily compressed)
• As a result of using a video codec, rather than compressing each frame individually, it can result in much smaller file sizes with similar quality.

I thought it added the association automatically...

I know, it is kind of slow. I have a few ideas for optimizations, but i'm not sure how much effect they will have. The README is a good idea, too.

Well, if the fps is reduced, it will play closer to the correct speed. However, it won't increase the framerate on the calculator; that will stay low.

I am personnally too lazy to open a command prompt, and I am too lazy to edit the bat to change the input file and the output file names. What I want is just to drag and drop the file and have an output with the right name.
So I edited the wrapper.bat file and replaced the ".\ffmpeg ..." line with this one (basically, just change the end):
.\ffmpeg.exe -i "%1" -r 24 -vcodec libvpx -vf "scale='if(gt(a,4/3),320,-1)':'if(gt(a,4/3),-1,240)',pad=320:240:(320-in_w)/2:(240-in_h)/2" -f ivf "%1".ivf.tns

I just wanted to share in case other people are as lazy as me, or if you want to put this in your final release
With this, you could also rename the wrapper "drag over me.bat" or something.
