ah, ok, now i get it, but this "uncompressed stream" means this, uncompressed stream ,not before the raw encoding but after the raw encoding, i was referring to the stream out of the chip, that means before creating any raw file, but as Sabastian said, you can't have both binned and unbined images out of the chip, you only can have one (or is it possible?)

i'm strating to program in java and i would love to contribute to the program, i've done a little aplication that converts a given number of frames at a given Fps to a SMPTE timecode(at the moment it's is only itegers, so i don't know how to do 29.97, but I'll learn)

are you interested in it?

Open source software development is all about collaboration and working together. So this is a good idea in any case.

My suggestion for the next lecture: Read about the float datatype :)

no, no i know it :) but what i don't wanna start getting is float frame numbers, so i need the computer to understand that you can't have 3.5 frames, there is 4 frames or 3 not 3.5, you know, all that kind of things, anyway sorry to go offtopic, i'll send you the program and you decide

i'm triying to do a java libarary of SMPTE workarounds like let the user enter a String and make the computer understant it as a SMPTE code, or give a exception signal back to the user if what he has written is not a SMPTE timecode... all that kind of things

This is still in a very rough and early condition but it should work and maybe already be kinda useful.

It lets you view the video live stream, shows camera infos and record video files to camera internal HDD.

Detailed instructions on how to setup and use are included as README.txt
Currently only works under windows.
Final version should be platform independent as long as your platform can run Java and has an mplayer build.


Please let me know if it worked, how it worked, etc.

OK, I've uploaded the files to the camera. Anyway, it a great start! It seems to be working fine. I had to restart firefox a couple of times till I found out how to use it, it seems to hang when you do something wrong.
I noticed that it only works when camvc is also running and updating the image. So camvc is showing a frame a second or something, but Elphel Vision is streaming the video at full FPS. The stream (on my fast laptop) is not real time, I think 0.5 sec behind.
So far my findings, I'll test it on the netbook tomorrow.
Again, great job so far!

Now that we have a dedicated forum for Apertus, it's time to close this particular
