Hi Ravi, Yes. In case of MP3 we may not need this structure, and there is nothing present in that structure as far as MP3 is considered. But I am trying to make it generic so that in case some other type of OMX components needs this kind of structure of some kinda of init data then how do I achieve this? I am going to test this feature with MP3 and when I get this structure (init time data) for time being in case of MP3 I am just going to ignore it. Also after digging a bit in the code I guess, in case of AAC or AMR some buffer (I think 2 or 5 bytes) is already being sent to the OMX component. I want to know how this buffer has been sent to OMX component from the parser.
