I had a similar issue with mpd. You should just be able to recompile ffmpegthumbnailer (and possibly thunar-thumbnailer). If you have trouble recompiling, add a comment to the ffmpegthumbnailer aur page. If you don't get a response in a day or two, then send pressh an email, as he is the maintainer of the package. ~pyther On Sun, 25 Jan 2009 22:02:47 -0200, Marco Antonio Gomez wrote: Using Openbox + Thunar + Thunar thumbnailer in Arch (completely updated), I noticed that thunar-thumbnailer, since last week, does not generate video thumbnails anymore. AFAIK, the problem is related to a new version of ffmpeg... My system messages show me that ffmpegthumbnailer looks out for a libavcodec.so.51 (lib that used to be provided by ffmpeg package, that was recently replaced by libavcodec.so.52.10.0). But the newer version of ffmpegthumbnailer in community, still looks for libavcodec.so.51. Then... obviously "error while loading shared libraries - no such file of direcrory". I've already tried to create a symbolic link named libavcodec.so.51 pointing to libavcodec.so.52.10.0, and when I try to do that, the ffmpegthumbnailer returns "Error: Could not find video stream" I've also tried to recompile ffmpeg and also ffmped-thumbnailer and all of it's dependencys from the newer versions of each one in AUR, but it was a frustrated attempt. Anybody else reports the same issues? If positive, any workaround to make it work? Regards, Marco Antonio Gomez.
