WARNING: you have chosen to build gst-ffmpeg against a random

external version of ffmpeg instead of building it against the tested

external version of Libav instead of building it against the tested

|

|

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

version of Libav involved will be closed immediately without further
|

investigation.

The reason such a setup can't be supported is that the ffmpeg API
|
||||
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 ffmpeg library to develop against. This makes it impossible
|
||||
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 ffmpeg. Even if gst-ffmpeg compiles
|
||||
with a randomly picked version Libav. 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
|
||||
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-ffmpeg

Please do not create or distribute binary packages of gst-Libav
