Ravi,
Your information is very helpful. But I dont understand this: if the parser
supports ASP then I expect to see at least some behaviors of OMX pipeline.
So is it because the parser recognized ASP and refused to go
on? An equivalent question is if I replace OMX component with an ASP capable
one, can I get that file played? My experiment showed that it still did not
work.
