Depacketize a MPEG-4 Stream with FOBS4JFM

[Nobody/Anonymous]

Hello everyone.

I'm developing a java client that receives via the network RTP messages in a java datatype byte[].
Soo far I can decode and interpret the RTP headers of the RTP messages but I cant understand the RTP Payload.
The RTP messages that I decode are encoded with MPEG-4.

What I want to know is if FOBS4JMF can help me decode and interpret the RTP payload. I dont need to see the video running, I only want to get some information from the RTP payload, like what kind of frame is inside of the RTP Payload and etc..

Can FOBS4JMF help me achieve this?

Thank you a lot for your attention.

I'm not certain if fobs can help you.  It's really a package deal, that handles all the stuff at once.  Also, I don't believe fobs can handle RTP - only file based media (either local or via http).

Having said that, the media type is 'supposed' to be encoded as part of the RTP header.  If you are already decoding it yourself, then you should be able to read the media type.  I'm not up on mpeg4 format yet, but am somewhat up on mpeg2.  For example, you would need to know something about the mpeg2 payload - is it transport stream or program stream, or simply raw type mpeg.  That's where it gets interesting.

Depending upon what you are looking for, this may or may not be a trivial task.
