This is a very bad idea. So bad in fact that words cannot express just how bad it is. Suffice to say that it is BAD. The GStreamer developers cannot and will not support a gst-ffmpeg built this way. Any bug reports that indicate there is an external version of Libav involved will be closed immediately without further investigation. The reason such a setup can't be supported is that the Libav API and ABI is in constant flux, yet there aren't any official releases of the Libav library to develop against. This makes it impossible to guarantee that gst-ffmpeg will work reliably, or even compile, with a randomly picked version Libav. Even if gst-ffmpeg compiles and superficially appears to work fine against your chosen external Libav version, that might just not be the case on other systems, or even the same system at a later time, or when using decoders, encoders, demuxers or muxers that have not been tested. Please do not create or distribute binary packages of gst-Libav that link against an external ffmpeg.
