[gst-embedded] Need help in aac decoder error

[Mayank Kapoor]

Hi,
I am trying to run the following pipeline on target board:

*gst-launch-0.10 filesrc location= AAC_stereo.aac ! aacparse ! myaac_decoder
! alsasink -v*

here myaac_decoder is the basic aac decoder element that i have written.But
when I run this pipeline I get following error.
My understanding from this error is that from aacparse I am getting event
NEW_SEGMENT with format as NULL(highlighted this error)and hence decoder is
not going ahead but i dont know how to fix this kind of issue.

Kindly suggest some method to fix it.
