Re: [Libav-user] Error while linking ffmpeg
Hi, you must make sure the libav* match the header when compiling your code. you may add -v option to see detailsI tryied the ffmpeg -v command and I get the following answerffmpeg version N-54345-ga35494c Copyright (c) 2000-2013 the FFmpeg developers built on Jul 2 2013 11:28:20 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --enable-shared libavutil 52. 38.100 / 52. 38.100 libavcodec 55. 18.100 / 55. 18.100 libavformat55. 10.101 / 55. 10.101 libavdevice55. 2.100 / 55. 2.100 libavfilter 3. 77.101 / 3. 77.101 libswscale 2. 3.100 / 2. 3.100 libswresample 0. 17.102 / 0. 17.102Missing argument for option 'v'.Error splitting the argument list: Invalid argumentWhat am I suppose to do with that ?

This is a bug in FFmpeg that is unlikely to get fixed (especially because the workaround is trivial), see: http://thread.gmane.org/gmane.comp.video.ffmpeg.cvs/66227/focus=66238 Sorry, Carl Eugen ___ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user
Re: [Libav-user] Error while linking ffmpeg : problem solve !
Hi, And thanks a lot for your responses and especially to Carl Eugen ! I just installed libvlc using apt-get and it installed avcodec in usr/lib. I deleted it and now it is compiling fine with both libvlc and ffmpeg. I would had never found that solution.

This tells you that you installed the libraries into /usr/local/lib (this is the default location and you did not specify another location) while you already have (another version of) libavcodec installed in /usr/lib - this generally cannot work. Please understand that I do *not* generally recommend to install your self-compiled shared libraries into /usr/lib - I just want to explain the problem (why linking fails for you independently of the mentioned FFmpeg bug).
