[gst-devel] RTMP streaming in web page

Hi, 


Thanks a lot for your message. 

I am trying to test your two command lines right now, but struggling a bit. 


The last Ubuntu packaged version for gst-base and plugins is 0.10.28, which does not include he config-interval option. 
I must then compile from the source, but I get errors with the configure in plugins-good which is searching for its dependencies in the /usr/bin folder. 

Is there a way to inform the configure file that my binaries are in a custom folder? I searched in the source, but failed for now :S. 


Anyway, the information you gave about the hardware encoder are interesting. I did not think that the problem could come from there. 
I will try to find the sources, so that a solution can be found. 


Thanks again,
I inform you as soon as I get more information.

Julien
