<html> <head> <style></style> </head> <body class='hmmessage'><div dir='ltr'> Hi All, I am writing my own plugin for a live audio/video source hardware, it has 1 ALWAYS video pad and 1 SOMETIMES audio pad. In my test application I connect to an xvimagesink and an alsasink. When i close the window i exit the main loop and set the pipeline state to NULL. In my plugin when going from PLAYING to PAUSE i call gst_pad_pause_task on each pad. The gst_pad_pause_task call for the audio pad is locked in GST_PAD_STREAM_LOCK The task for the audio pad is locked in gst_base_sink_wait_preroll call within the gst_pad_push call Shouldnt gst_pad_pause_task be called when changing PLAYING to PAUSE ? Should i push/send a special event on the pad before calling gst_pad_xxx_task function ? Is there principle to follow to ensure no deadlocks when calling a gst_pad_xxx_task function ? Thanks for your help, Pierre </div></body> </html>
