Hi, how the pullreader tries to get data from the push reader and push it downstream?... There should be a loop running on its sink pad to do so (by doing a get_range upstream ) yes, in pullreader sinkpad have the pull_range function which will call pushreader set_getrange function. Loop function is running on pullreader sinkpad. Is the get_range from alsasink, (I m not sure though because, normally the upstream elements push data to alsasink) proxied to the push reader? No, get_range from pullreader. In loop function, i am pushing data to alsasink using pad_push.
