Hi! I have some problems when I install the gst-ffmpeg-0.10.7 package. When I'm launching the "make" command, I received thousands of warnings, and after that, even thought FFmpeg for Gstreamer is well installed, it lacks some encoders. I tried to do "make check" to see if I can find a trace of the problem, and this is what I get : Making check in gst-libs Making check in ext Making check in ext Making check in ffmpeg Making check in libpostproc Making check in libswscale Making check in docs Making check in common Making check in m4 Making check in tests Making check in check CC libavcodec-locking.o LINK
