Comment (by kuroneko):
FWIW, today I also came across this issue. I use ffmpeg (2.7.2) to extract
the stream from a GStereamer equipped IP camera.
The server response for the seesion ID is like this:
Session: .5U+3chv$$2uwBK.; timeout=60
As soon as the first $ is encountered it (ffmpeg) attempts to skip a
number of bytes based on the following data. What puzzles me is that the
RFC mentions the "safe" character range as follows:
safe = "\$" | "-" | "_" | "." | "+"
Note the backslash in front of the $. Whatever I can do to help, let me
know.
