With the current ebuilds no matter what you set for use variables ffmpeg or gstreamer. Gnash will be compiled with ffmpeg for the media handler and sdl for sound. The ebuild is trying to set --enable-sound=gst when using the gstreamer use setting. #--enable-sound=gst,sdl if use gstreamer; then myconf="${myconf} --enable-sound=gst" else myconf="${myconf} --enable-sound=sdl" fi This is useless as when gnash checks that the media handler is still set to ffmpeg (the default) it ignore's this setting and use's sdl instead. The only possible options are: ffmpeg as media handler and sdl for sound. mad as media handler and sdl for sound. gst as media handler and gst for sound. Everything else is invalid. I suggest your replace the following code: #--enable-sound=gst,sdl if use gstreamer; then myconf="${myconf} --enable-sound=gst" else myconf="${myconf} --enable-sound=sdl" fi if use ffmpeg; then myconf="${myconf} --with-mp3-decoder=ffmpeg" fi With something similar to: #--enable-media=gst||ffmpeg||mad if use gstreamer; then myconf="${myconf} --enable-media=gst" fi if use ffmpeg; then myconf="${myconf} --enable-media=ffmpeg" fi if use !gstreamer && use !ffmpeg; then myconf="${myconf} --enable-media=mad" fi This will set the media handler using the use words ffmpeg and gstreamer (will default to mad) which in turn will automatically set the correct sound option (gst,sdl). You should also add the option --disable-debugger to the ebuild. It improves performance a little.
Created attachment 123839 [details] Example ebuild With the example ebuild ffmpeg has priority over gstreamer and mad. Gstreamer has priority over mad.
Thank you. I added your patch
