Re: gstreamer-devel Digest, Vol 95, Issue 16

Hi all, I'm Mario again.

I did some changes:

Add some queues
Add some caps filters

The new code is:

#include <gst/gst.h>

#include <stddef.h>

#include <stdlib.h>

#include <string.h>

#include <stdio.h>

#include <gst/app/gstappsrc.h>

#include <malloc.h>

#include <unistd.h>

#define TOP 10

#define HEIGHTF 512

#define WIDTHF 640

int main(int argc, char *argv[])

}

It still compile without errors but the new warnings are:

You are trying to set *width * property on GstAppSrc which is not correct.
Though I could not find in the log.
There is some problem in GST_OMX_CONFIG* environment.

Hi again,

"In you mail you have not mentioned about your problem"

Yes, sorry, it was my fault. I ansewered to my own thread when I did some changes, please, to find my app problem, go to the previous treath called "appsrc warning" which also was posted by me.

Mario.
