Basic filmmaking interface for the 333

This is a really simple interface for the camera I wrote in about an hour or so the night before a film shoot a while back. In the very least it will demonstrate the basics of configuration and streamer operation.

It provides keyboard input for setting basic camera settings. Changes can be viewed in real time even while recording. Do not send too many requests or it will lock up the camera and you will have to reset it.

Up - moves up one option in the menu
Down - moves down one option in the menu
Left - Decreases a value / activates option
Right - Increases a value / activates option

Once this page loads it automatically configures the camera in the following order

1) Disables the auto exposure
2) Starts the streamer
3) Sets the settings - most importantly
o 2000x800
o 24 fps
0 85% quality

I realize this is not a complete solution and it was not meant to be. Just something for my personal use, and it worked great. Its far from perfect, really just a quick hack but im posting it here just in case it helps others.

To install it:
O Download file
O FTP into camera and upload to /usr/html/
o browse to 192.168.0.9/film.html

What does not work:
o white level
o black level

Requires Firefox. No IE support.

If it does not work refresh the page. If its still broken, reset the camera and try again.

This has not been tested under the elphel livecd. It should work, but its possible there may be a problem with the older version of firefox.

The interface im using right now is PHP based and is much better designed. Its got a lot of advantages and does not have to be uploaded to the camera. It can record audio and keeps a MySQL database for time data, sound sync, and some other basic data. But unfortunately its a work in progress and I don't have time to put it together into something I can distribute yet.

That's a wonderful start Daniel. I'll try it on my 333. Great to see software development. Andrey is working on the software for the board to record directly to hard disk (for the 353 model)

EDIT:
Is this for Windows or Linux?

It will work under both Linux and windows. Just upload the html file to the camera and browse to it. Just make sure you use Firefox. For simplicity I did not make it cross browser compatible.

It will NOT work unless you upload it. The reason is that ajax calls to another domain can be problematic. A security feature of current browsers disables it. There is a way to get around it but I wanted to keep this simple. I have read that Firefox 3 will solve this.

Besides... this way if you use the live cd you will have the interface available at every boot, and any os.

In my new software I just use php and curl.
