I’ve been trying to setup my pipeline <o:p></o:p> <o:p> </o:p> uridecode<o:p></o:p> -> audioconvert -> appsink_audio<o:p></o:p> -> videoconvert -> appsink_video<o:p></o:p> <o:p> </o:p> to be a preroll pull mode pipeline.<o:p></o:p> When I add debug to my GST event loop I can see that all the elements are moving into the GST_PLAYING state except for the appsinks (both audio and video). They are moving from NULL -> READY. But they don’t budge out of READY.<o:p></o:p> <o:p></o:p> How I setup my pipeline:<o:p></o:p> When I init the pipeline I add all elements and then set the locked state on all elements downstream of the uridecode and set the pipeline to GST_PAUSED<o:p></o:p> When I get a pad_added event I add a GST_PAD_PROBE_TYPE_BLOCK_DOWNSTREAM probe.<o:p></o:p> In the downstream block callback I unlock the elements associated with that pad (audioconvert, appsink_audio or videoconvert, appsink_video) and link the pad to the audio/video convert element.<o:p></o:p> When all the downstream block callbacks are called I send a message to my GST main loop telling it to set the pipeline state to GST_PLAYING.<o:p></o:p> <o:p></o:p> At this point I see lots of state changes occurring across all my elements as they move into PLAYING state. All except those 2 appsinks….<o:p></o:p> <o:p></o:p> Is there something about the appsink element that I am missing? When I turn on GST_DEBUG the last mention I see from my audio appsink is this:<o:p></o:p> gst_bin_change_state_func:<controller-pipeline> child 'appsink_audio' is changing state asynchronously to PLAYING<o:p></o:p> <o:p></o:p> Anyone out there got any ideas on what I am doing wrong here or how I might proceed with debug?<o:p></o:p> <o:p></o:p> Thanks in advance!<o:p></o:p> John<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> Accenture Global Solutions Limited, 3 Grand Canal Plaza, Grand Canal Street Upper, Dublin 4<o:p></o:p> This e-mail and any files transmitted with it are confidential and are intended solely for the use of the individual or entity to which they are addressed.
