streamer

[Cristiana Tenti]

Hello,
I'm a new user :)

I'm working on a simple project and for that I only need to a software for
uclinux to acquire a raw image from my usb webcam.
On Ubuntu I'm using STREAMER but I cannot find the source code to install it
on my uclinux platform.

Anyway I found xawtv and I saw that this usefull software has as tool
STREAMER.

Do you know if it is possible compile only streamer and not all package of
xawtv?

Please, if you can help me answer me!!!

Thank you in advance,

Best Regards

You may compile whole xawtv against the same kernel that you will use for
uclinux, with a development PC. Then, copy and move the streamer to your
target uclinux platform. Sure, the streamer is a really good capture
tool/utility. I like it too.

Hi,
first of all thank you for your answer!!

So, I can compile every in my Ubuntu-pc and then what have I to crosscompile
for uclinux?

Can I only copy and move streamer?
And what is it? an executable file stand alone?

Thank you so much!!

Yes, stand alone executable, plus necessary libraries.

Dear Cristiana,

only a warning for you.

You must have the right speed on USB and also very fast acquire library.

First of all, please check if your USB platform is USB2.0

If you don't have USB 2.0 in your embedded target board you cannot grab 
anything from your cam: there isn't enought throughput

I had the same problem some months ago and i didn't realize why it 
wasn't working.

If you only need to grab a still image i can send a very simple software 
to you that you can cross-compile for your platform.

It's based on V4L standard (so you need such library for your embedded 
platform) and, of course, you need the driver for your USB cam

Bye

Fabrizio

     You can also check mjpeg-streamer project. I have been used it for 
jpeg frame streaming, in addition it can give raw images.

There is no link to mjpg-streamer from

the source code could be downloaded from
http://sourceforge.net/projects/mjpg-streamer/

Re: streamer

[Jeyner Gil Caga]

Hi Cristiana,

I have done this with PPC440Epx about 2 years ago but I don't have the
modified XAWTV source codes, configuration and the makefiles  right now.
As far as I can remember, I did the following things and I suggest you do
the same:

-make sure that your USB webcam works in normal linux installation, not
uclinux.
-determine the basic plugins needed to make it work, i think v4l2 and jpeg
plugins are needed, this case, you need to edit the makefiles so that it
will only compile the necessary plugins. in XAWTV, there is a folder for the
plugins. try to take a look into it. also, take note that when you install
the XAWTV package, the plugin directory should only contain the basic
plugins i mentioned.
-once you know the basic plugins, try to cross-compile them. i think you
need to set your plugin directory. after cross compiling, try to copy the
streamer, its plugins and libraries.
 I hope this helps.
