[gst-devel] Scheduling Problem

Hi,

I am a newbee to gstreamer. I am trying to explore about push and pull based
scheduling in gstreamer.

I wrote pushreader, pullreader plugins.

In pushreader - sink pad is exposed with chain function, src pad with
set_getrange function. In chain function whatever data got from alsasrc, I
stored that buffer into plugin internal buffer. Getrange function is using
this internal buffer.

In pullreader – sink pad is exposed with getrange function, it tries to get
data from pushreader and push that data to alsasink.

Pipeline is alsasrc ! pushreader ! pullreader ! Alsasink

When I tried to execute the above pipeline, only getrange is scheduling,
Chain function is not scheduling.

Please help me to solve this problem.  

Thanks
Nagaraju K
