[gst-devel] 答复: amr-wb seek problem

[Jorney_Dong at asus.com]

Thanks for your reply!

There is not a blocking in every seek event. 
And the gst_element_seek's return value is TRUE when there is a blocking.

I didn't find a src pad event handler in amrwbdec in ugly(15 or 16). but I's not sure how to handle src pad event in AMRWBDEC, 
could you give me a sample? Thanks!
