Question

On the Android platform with ARM &/ DSP which decoder will be faster: MPEG-4 or MPEG-2 or 3GP? And why?

Answer 1

"Faster" is a relative term. Impossible to answer given the information in your question. But speaking in general terms, MPEG-4 is a lot more complex than MPEG-2. The list of features are too long to list here... One of the features in MPEG-4 ASP is qpel that is not present in MPEG-2.

BTW, 3GP is a container-format and not a decoder. See here
