Commit e3c68867 authored by Gildas Bazin's avatar Gildas Bazin

* modules/stream_out/transcode.c:

   + new options to allow forcing an encoder and passing options to it.
     (aenc=foo{optionbar=bar,etc...},venc=foo{optionbar=bar,etc...} where foo is the encoder plugin name).
   + got rid of aopts/vopts which is not needed anymore ;)
