Re: [Linphone-users] Using test_rtprecv Applicatoin

[Eduardo Bezerra]

Hi,


  I've tried to do the stuff. I made some changes in recv and I created the send.
But the versions above don't use files. The sender gets from the mic, codifies using
MUAlaw and the sends using oRTP. The recv is exactly the original, except that
I removed the dispatcher and the file handler MSFilters:

Hi All,

How to run the test_rtprecv application present in the
mediastream. Where do i find the
equivalent rtpsend application for it ?

I would like to establish a rtp session between the
target and the another host PC, and
would like to playout some .wav files to my target. Is
it possible to do the
same using the test_rtprecv application. Am i on the
right track ?.

I Appreciate your inputs on this.

Thanks
Vanitha
