Hi,
The behaviour of the sdpops module is not fully clear to me.
Lets say in the INVITE contains in the m= line the payloads 0 99 but has no a=
line for codec 0 / PCMU, Would the sdp_keep_codecs_by_name(“PCMU”) keep PCMU ?
What about the case that the INVITE contains in the m=line only the payload 99
but shows an additional a=line for codec 0 / PCMU. Would the
sdp_keep_codecs_by_name(“PCMU”) keep PCMU ? If yes, would the extra mtype
parameter prevent that? e.g. sdp_keep_codecs_by_name(“PCMU”, mtype)
What happens when several m= lines are present? Does sdp_keep_codecs_by_name
consider all m=lines ? Are the treated separately?
What happens to payloads which are not in the hard-coded list in sdpops_data.c
? Can they be used with the sdpops functions?
Thanks for your hints.
Best Gerry
