Re: [Linphone-developers] mediastreamer: undefined reference to `ms_sws_freeContext'

[Simon Morlat]

Hi Peter,

Thank you for reporting this issue.
You are probably building mediastreamer2 with --enable-sdl .
On linux sdl dependency has been deprecated in favor of X11+Xv subsystem
 (you just need libxv headers installed to build this new module in
mediastreamer2).
However the SDL module should be able to build for platforms without
X11, so I'm working on fixing this issue.
The ms_scaler_context*() calls are replacing the old ms_sws*() ones.
