<DIV>Hi Ross,</DIV> <DIV> </DIV> <DIV>Thank you for the reply. I have tried to stream a Speex encoded file (in the ogg format) with the Live555 Streaming Server but it does not seem to work. I think that the streaming software is checking the file extension of the file to be streamed in order to determine if it can be streamed or not. When I try to stream the file it comes back with a file not found message from the server. I was able to successfully stream .wav files though.</DIV> <DIV> </DIV> <DIV>VLC does include software to decode and play Speex encoded audio but it doesn't seem to be picking up the SDP and selecting the correct codec in order to play the stream. I will have to work with the VLC source and/or developers to see if this can be fixed.</DIV> <DIV> </DIV> <DIV>Thanks for your help and Live555 software! I have already recommended it to some friends.</DIV> <DIV> </DIV> <DIV>Randy<BR><BR><B><I>Ross
