Nspire Movie Player - alternative to nPlayer
« on: March 07, 2012, 05:30:11 am »
Inspired by nPlayer, I spent a long time trying to write an improved video player and looking for a easy way to get compression on the video files.

Today, I managed to incorporate JPEG compression into my program and I'm happy to say, I have managed to bring the file size of a movie file from ~131.84MB per minute (sequential raw bitmaps at 15fps) to a measly ~2.86MB per minute (sequential JPEGs at 15fps).

I can play the whole Rickroll song while only using about 10.5MB for the movie file. Combine that with the ~90MB free space you get on a CX, you could probably fit about a half an hour movie or anime on it.

Although it's a WIP, I probably won't have any time to further improve it (school yah see). The nPlayer developer(s) are welcome to use my ideas and code (code is GPL'd though) to improve nPlayer.

Anyway, here's the video and link to the source code.

Wow, well done! This definitely reduces files down to a manageable size, and will help greatly. Looking forward to seeing progress on this!
EDIT: Not really sure how to compile this exactly [shrug] :P

This looks great !
However, could you post a compiled tns file and some kind of a tutorial so we know how to use it ? ;)

Good job, as usual ;)

I've created a news about this interesting new development on TI-Planet , in French.

Looks nice. Somebody definitively gotta compile this so people can use it immediately. I might eventually post a news too.

It probably won't work on the older Nspires, right?

Thanks for the feedback!

I'll polish it up a bit before a binary release since it's quite ugly right now :P I'll probably have it up by the end of tomorrow.

Edit: Thanks to the CX's bigger storage area, I managed to get a full episode of an anime onto the calc!

It doesn't take much to port it to the old calcs. I'll get around to it after I polish things up.

Yay ! Thanks :D
However, my calc crashed :P
I sent the player, the test video you included and a new ndless.cfg.tns (so it works with file associations) then ran the video. The calc played the video then shut down, and no key responded, except the reset one :P

edit: also, the quitting key is not that obvious :P
edit: also, not everybody has a working Ndless SDK D:. Wouldn't it be possible to have another way to convert videos ?

Haha, like I said, it's a very early version. Which calc did you run it on? I have yet to test it on classics.

Yep, more polish coming up! I'll change the quitting key on the next release.

You don't need the Ndless SDK to convert videos, you just need a working C compiler to compile the helper program. I understand not everyone has one installed on their system though so I'll try to compile the helper program for Windows and release a binary.

Wait, in fact it seems that it didn't crash O.O
But after it ran the video, it diplays a black screen and waits for the 5 key to be pressed.
And when I tried all the keys, I pressed them quickly, maybe it didn't detect it when I pressed it.
Now it is ok, I press 5 at the end and it quits :)

I ran it on a CX CAS

Yeah, thanks :D
My sister uses a C compiler but I don't know how it works so I'll wait for your release :P
