217 ======================================================================
218 WARNING: you have chosen to build gst-ffmpeg against a random
219 external version of ffmpeg instead of building it against the tested
220 internal ffmpeg snapshot that is included with gst-ffmpeg.
222 This is a very bad idea. So bad in fact that words cannot express
223 just how bad it is. Suffice to say that it is BAD.
225 The GStreamer developers cannot and will not support a gst-ffmpeg
226 built this way. Any bug reports that indicate there is an external
227 version of ffmpeg involved will be closed immediately without further
230 The reason such a setup can't be supported is that the ffmpeg API
231 and ABI is in constant flux, yet there aren't any official releases
232 of the ffmpeg library to develop against. This makes it impossible
233 to guarantee that gst-ffmpeg will work reliably, or even compile,
234 with a randomly picked version ffmpeg. Even if gst-ffmpeg compiles
235 and superficially appears to work fine against your chosen external
236 ffmpeg version, that might just not be the case on other systems, or
237 even the same system at a later time, or when using decoders,
238 encoders, demuxers or muxers that have not been tested.
240 Please do not create or distribute binary packages of gst-ffmpeg
241 that link against an external ffmpeg. Thank you!
