Hello everybody,<br>
<br>
I am learning gstreamer. My goal is making a simple video mixer<br>
application, that will allow the user to select between several input<br>
streams (coming from FireWire, Webcam, local file, ...) on real time.<br>
The key feature is that there is a continuous output video stream, just<br>
like it had been generated with a video editor previously.<br>
<br>
As I am a newbie with gstreamer, as a training, first I am trying the<br>
same with audio streams, extending the "helloworld.c" given in gstreamer<br>
documentation. The very first step is a small program that concatenates<br>
two ogg files, but it fails because the second stream is not written. (I<br>
attach the source file). Also, if I try to switch the streams when the<br>
first song is not over (other variation of the program), I get a<br>
run-time "data stream internal error".<br>
What I am doing wrong?<br>
<br>
Thanks for any help,<br>
<br>
Andr?s<br>
