[speex-dev] auto-detection of frame boundary

[Tongbiao Li]

Here's the situation: 3 frames are being transferred back to back over
RTP.  The total payload is known (thus the TOTAL frame size).  We'd like
to decode all 3.

 

According to IETF RTP Profile (appendix C, of Jean-Marc's Speex Codec
Manual, verison 1.0),  "it's only necessary to consider the sequence of
bits as output by the Speex encoder, and present the same sequence to
the decoder", I kind of got the impression that length-prefix PER FRAME
is not necessary, as long as speex_decode() is called 3 times.

 

Is this true ?

 

 

Thanks all,
