[gst-devel] GST_ELEMENT_ERROR not working ?

[Antoine Tremblay]

Hi,

I'm using gstreamer 0.8.7 and i'm having problems with
GST_ELEMENT_ERROR in the doc it says : Utility function that elements
can use in case they encountered a fatal data processing error. The
pipeline will throw an error signal and the application will be
requested to stop further media processing.

But when I call it in a chain function and return from the chain, my
other plugins (especally the loop demuxer I use ) won't stop,,,  any
ideas ? Isn't it supposed to propagate ?

Here's the complete debug :
