While compiling, this warning is emitted:
xpra/x264/codec.c:1623:3: warning: implicit declaration of function 'change_encoding_speed
I found this function defined in xpra/x264/x264lib.c, so I made a patch to declare this function in xpra/x264/x264lib.h
Thanks, the exact same patch was already applied 2 weeks ago: x264lib.h - r777
Note: 0.2.0 is not going to be maintained long-term and contains various bugs (including memory leaks, etc). If distributors want to ship a version, I would suggest waiting for 0.3.0 (to be released soon)
