[Freeswitch-users] fs_encode opus to wav is it possible

[Raymond]

Maybe ,you can record it ,save it as "raw" format . Plz look at wiki  to ensure it.


Wiki  is  the first place to find the solution.

Hi,

i want to analyze the audio that i received from the link... recording is not an options since it introduces transcoding in fs. 

I do this method for all other codecs like g722, g729, (PCMU/A not need wireshark can play it or you can save as .au), i get the all the rtp pkt and convert then with fs_encode to wav to reproduce with normal player.

Bur for opus i can't figure out how to make it work... i already try to pass the fmtp args negotiated in the sdp with no luck..

HI,

why don't you  just record  to an wav file??
And "wireshark -> rtp streams -> save as raw format "---------------------- you just got a file with ip packet format. not the "raw audio format"
