Packing multiple frames in a RTP packet
Hello,
*Background:*
The RFC 5574 suggests the RTP payload format for the speex codec. The
payload formation is straight forward; the encoded frames are to be
concatenated one after another. Once we have appended desired number of
frames, we have to pad the stream with 01111 sort of sequence to ensure that
payload ends on a octet boundary.
*Observation:*
I am using the speex encoder at 2150 Kbps

Packing multiple frames in a RTP packet
You cannot concatenate bytes because Speex frames don't necessarily end
on octet boundaries. You need to call the encoder multiple times on the
same SpeexBits bitpacket.
