[gst-devel] Ignoring errors of fdsink

[Arnout Vandecappelle]

 Hoi all,

 I have a pipeline with a tee element connected to several fdsink elements.  
Each fdsink writes to a socket, which can be terminated by the remote end at 
any time.  If this happens, the chain function of fdsink posts an error on 
the bus and returns GST_FLOW_ERROR.

 Since I want the pipeline to continue when one of the clients disconnects, I 
handle the error message on the bus and remove the fdsink.  This often works.  
Indeed, the GST_FLOW_ERROR is captured by a queue in the pipeline and doesn't 
arrive at the tee element.  Unfortunately, it is possible that the next 
buffer is pushed into the queue before I can handle the error message.  In 
that case, the queue returns a GST_FLOW_ERROR as well, it goes all the way up 
to the source element, which sends an EOS down the pipeline.

 Is there any way to intercept the error before it passes the queue?

 If there is no solution, I think I'll patch the tee element to (optionally) 
ignore downstream errors until all pads are in error.

 Regards,
 Arnout
