[Linphone-developers] mediastreamer filters description / where to find the payload string ?

[Albrecht Andrzejewski]

Sorry, i initially posted it to the linphone-users ml, which is not the best 
place to ask. The original question was : 

I want to display the codec name used during a call.

I guess this information shoud be attached to the _AudioStream struct 
associated to the call.
This stream is composed by several filters. Some are self explaining, but 
others are confusing.

I expected the encoder and decoder filters to describe the payload used during 
the call but these are NULL when i examinate this struct attached to my call in 
callState LinphoneCallConnected.

So can you describe me briefly what should be in encoder / decoder during a 
call ? 

here is the list of all filters declared in the audioStream structure.

       MSFilter *soundread;
       MSFilter *soundwrite;
       MSFilter *encoder;
       MSFilter *decoder;
       MSFilter *rtprecv;
       MSFilter *rtpsend;
       MSFilter *dtmfgen;
       MSFilter *dtmfgen_rtp;
       MSFilter *ec;/*echo canceler*/
       MSFilter *volsend,*volrecv; /*MSVolumes*/
       MSFilter *read_resampler;
       MSFilter *write_resampler;
       MSFilter *equalizer;

Thanks,
