223 ======================================================================
224 WARNING: you have chosen to build gst-ffmpeg against a random
225 external version of ffmpeg instead of building it against the tested
226 internal ffmpeg snapshot that is included with gst-ffmpeg.
228 This is a very bad idea. So bad in fact that words cannot express
229 just how bad it is. Suffice to say that it is BAD.
231 The GStreamer developers cannot and will not support a gst-ffmpeg
232 built this way. Any bug reports that indicate there is an external
233 version of ffmpeg involved will be closed immediately without further
236 The reason such a setup can't be supported is that the ffmpeg API
237 and ABI is in constant flux, yet there aren't any official releases
238 of the ffmpeg library to develop against. This makes it impossible
239 to guarantee that gst-ffmpeg will work reliably, or even compile,
240 with a randomly picked version ffmpeg. Even if gst-ffmpeg compiles
241 and superficially appears to work fine against your chosen external
242 ffmpeg version, that might just not be the case on other systems, or
243 even the same system at a later time, or when using decoders,
244 encoders, demuxers or muxers that have not been tested.
246 Please do not create or distribute binary packages of gst-ffmpeg
247 that link against an external ffmpeg. Thank you!
