[Libav-user] AMR codec/format, rfc3267 saved file

I have a file exported from Wireshark for an audio RTP stream with an
AMR codec. I cannot read it with

  ffmpeg -fmt amr -acodec amr-wb

because rfc 3267 adds an extra byte ahead of the AMR "table of contents".

It is very easy to write code that ignores this one byte, but that
means recompiling for all platforms.

The question is, maybe there already is a way to do that without
recompiling the libraries? Best, if there is some advanced option for
ffmpeg command line to skip one byte before parsing packets with amr
format or codec.
