+ ======================================================================
+ WARNING: you have chosen to build gst-ffmpeg against a random
+ external version of ffmpeg instead of building it against the tested
+ internal ffmpeg snapshot that is included with gst-ffmpeg.
+
+ 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 ffmpeg involved will be closed immediately without further
+ investigation.
+
+ The reason such a setup can't be supported is that the ffmpeg API
+ and ABI is in constant flux, yet there aren't any official releases
+ of the ffmpeg library to develop against. This makes it impossible
+ to guarantee that gst-ffmpeg will work reliably, or even compile,
+ with a randomly picked version ffmpeg. Even if gst-ffmpeg compiles
+ and superficially appears to work fine against your chosen external
+ ffmpeg 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-ffmpeg
+ that link against an external ffmpeg. Thank you!
