Re: [gst-embedded] Need help in aac decoder error

[Mayank K. <er....@gm...>]

Hi Tim,
Thanks for the reply.....
This parser is not my parser, it is Gstreamer's parser taken
from bad-plugin, I have also tried the same parser with "faad" element to
play aac file on my ubuntu desktop and it works fine But the same parser
gives this error on my board with my decoder.

Still try to find the issue.........
