[gst-devel] How to play video using gstreamer/c++

[Marlos C. Machado]

Hello, I need to play this line on gstreamer using c++:

filesrc location=Video2.avi ! decodebin2 name=dec ! queue ! ffmpegcolorspace
! autovideosink dec. ! queue ! audioconvert ! audioresample ! autoaudiosink

This code does this:

*#include <gst/gst.h>

int main(int argc, char *argv[])
{
 char str [] = "filesrc location=Video2.avi ! decodebin2 name=dec ! \
                   queue ! ffmpegcolorspace ! autovideosink dec. ! \
                   queue ! audioconvert ! audioresample ! autoaudiosink";
 GError *error = NULL;
 GstElement *element;

 gst_init (&argc, &argv);
 element = gst_parse_launch(str, &error);

 gst_element_set_state (element, GST_STATE_PLAYING);

 if (!element) {
   fprintf (stderr, "Parse error: %s\n", error->message);
   exit(1);
 }

 while(1){}

 return 1;
}*

But I need to play this video on a texture, how do I bind the video with a
texture in OpenGL, for example? I mean, I do not know how to access the
stream, the code above plays on a window created by gstreamer.
If I'm able to access the stream i'm able to bind it to OpenGL. I'd prefer
to use no-specific OpenGL plugins since I do not know what rendering system
I'm going to use.

Thanks a lot!
