I've tried everything to avoid using h263 depayloader, but at the moment
I see that I have no other option. Since I'm working with streamed audio
and video between a PC and a Nokia N800, I have no other option than
using h263 depayloader. (seems the feasable option due my deadlines).
I have two situations here. One is if I use h263 encoder and payloader
on the PC side, then I don't have a h263 depayloader on the Nokia N800
(but I have a proper h263 decoder).
The other is if I use h263p encoder and payloader in the PC side, then I
have a h263p depayloader in the Nokia N800 but I don't have a proper
h263p decoder int the Nokia side.
It sounds a bit of incompatibility between depayloaders and decoders
that link eachother from the Nokia side part.
