Hi,
I’m trying to filter a trace of an AMR rtp stream. The
AMR (narrowband, nb) is coded in “bandwidth efficient mode” and I’m
guessing that’s why I don’t get my filter to work.
I want to filter on the “frame type index” and
found the following filter that I thought would work:
amr.nb.toc.ft == 5 (where 5 is the rate 7,95)
However, applying this filter on my trace gives an empty
result. If I display the whole trace I see that there are several ARM packets
with this frame type index.
Anyone have an idea on what filter I should try instead or
if I have done something wrong? I’m not sure if I’m allowed (or
should) send attachements to this mailing list, but I have a trace that I can
post if someone is interested in trying different filters on my capture file.
Let me know if I should do this
Regards,
