224 ======================================================================
225 WARNING: you have chosen to build gst-ffmpeg against a random
226 external version of ffmpeg instead of building it against the tested
227 internal ffmpeg snapshot that is included with gst-ffmpeg.
229 This is a very bad idea. So bad in fact that words cannot express
230 just how bad it is. Suffice to say that it is BAD.
232 The GStreamer developers cannot and will not support a gst-ffmpeg
233 built this way. Any bug reports that indicate there is an external
234 version of ffmpeg involved will be closed immediately without further
237 The reason such a setup can't be supported is that the ffmpeg API
238 and ABI is in constant flux, yet there aren't any official releases
239 of the ffmpeg library to develop against. This makes it impossible
240 to guarantee that gst-ffmpeg will work reliably, or even compile,
241 with a randomly picked version ffmpeg. Even if gst-ffmpeg compiles
242 and superficially appears to work fine against your chosen external
243 ffmpeg version, that might just not be the case on other systems, or
244 even the same system at a later time, or when using decoders,
245 encoders, demuxers or muxers that have not been tested.
247 Please do not create or distribute binary packages of gst-ffmpeg
248 that link against an external ffmpeg. Thank you!
