[Speex-dev] Playing captured speex frames

[Shridhar, Vasant]

Speexdec is expecting the frames to be wrapped in an Ogg frame I believe.  Since you have the raw data can't you just add the Ogg header information to this before passing it to Speexdec?

Thanks for the suggestion, but Wireshark already does what you've
suggested. There's an option to save the raw payload to a file. This
file only has the speex frames (no udp+rtp headers). speexdec still
complains about it not being a valid speex file presumably because the
file is missing the header.

Apart from manually constructing a header and prefixing it to the
file, any other ideas?
