Dear all, My OS is Debian Wheezy (testing) amd64 and I've just updated libav family library to the testing versions. Now gstreamer is not able to load anything from ffmpeg. The following error is shown: (gst-plugin-scanner:6908): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /usr/lib/libavformat.so.52: symbol ff_toupper4, version LIBAVCODEC_52 not defined in file libavcodec.so.52 with link time reference gstreamer0.10-ffmpeg v0.10.11-4 libavcodec52 v4:0.6.2-3 (when i had 4:0.6.2-1 it worked) libavformat52 v4:0.6.2-3 (when i had 4:0.6.2-1 it worked) I have also installed the same versions for the development packages. Should the testing gstreamer0.10-ffmpeg package be re-released for the new libav libraries? Or it is another problem? Best Regards, Angel
