RTP

Hello,

I'm currently writing a SIP-Client. Now the sip-part is complete an I have "only" to work on the rtp-part.
Ireceive all the video and audio-datawithin aRTP-Stream. My problem is, that I didn't have much experience with audio/video-codecs. Currently I use portaudio an some OpenSource-Librarys to play the rtp-streams on my audiohardware. But I want to try it with IPP.

Is it possible in IPPto directly render rtp-buffer to a audio/video renderer?
Or maybe someone can point me to some direction, with more information about this topic ;-)

Thanks!

best regards,
Stefan

Hi Stefan,

there is comment from our expert:

A: Is it possible in IPPto directly render rtp-buffer to a audio/video renderer?

Q: No, first you need to decode payload of rtp-buffer with certain audio/video decoder. Then render it.

Note: IPP video decoders operate with whole frames while payload of rtp-packets is usually an arbitrary piece of data.
