[Gstreamer-openmax] File not playing with Playbin...

[kommanapalli srirammurthy]

Hi Stefan,

After changing the Caps of MyDemuxer, MyDecoders,& MySinks filters i am able to load some of filters with playbin.

But except MyAudioSink all other elements are loaded by playbin( MyDemuxer,
MyVideoDecoader, MyVideoSink, MyAudioDecoder). Here no other audiosink
is loaded(eg : Pulsesink etc...).

when i am tested same chain by enableing export GST_DEBUG=GST_ELEMENT_FACTORY:3 log then i came to know that even autoaudiosink not getting loaded.

Debuglog:

Pipeline is PREROLLING ...
^CCaught interrupt -- handling interrupt.
Interrupt: Stopping pipeline ...
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
^C

Due to audiosink not loaded, pipeline is not getting PREROLLED. 
Why autoaudiosink not loaded here. 

If any one have an idea please reply.

PS: When my filters not registered same chain is working with standard elements.

 Thanks & Regards
