Hi, gstreamer-devel:     One more thing: alsasink inherits from gstbaseaudiosink which inherits from gstbasesink. GstBaseAudioSink overrides "render" function of GstBaseSink, so don't forget to take care of gstbaseaudiosink.

Blocking is a common problem when developing gstreamer applications, at least for me. And my solution is first find out where it blocks -- mostly always blocks at basesink.     I noticed your basesink used push mode so you can first add printf codes in "gst_base_sink_chain" --> "gst_base_sink_chain_unlock" --> "gst_base_sink_queue_object_unlocked" ......

And when i do $gst-launch filesrc location=test.ogg ! decodebin ! audioconvert ! audioresample ! filesink location=test.raw it writes the decoded raw samples into the file and I am  able to play test.raw in application like cooledit But if I do $gst-launch filesrc location=test.ogg ! decodebin ! audioconvert ! audioresample ! alsasink it goes into infinite loop. The alsasink plugin is not able to detect the alsadriver I guess. How do I debug this problem? Pls help me Regards Vinod James </div></div><div class="Ih2E3d">------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
