[Kdenlive-devel] --disable-mmx for MLT and other options for ffmpeg

[Simon A. Eugster]

Some weeks ago I read something about MMX being supported on 64bit as well 
(but unrelated to MLT, so I skipped most of the text). Now I tried to 
compile MLT without the --disable-mmx flag, and it seems to work here (I 
don't know what MMX depends on; Using kernel 2.6.34, gcc 4.4.5).

And about ffmpeg options listed here: 
<http://kdenlive.org/user-manual/downloading-and-installing-kdenlive/installing-source/installing-ffmpeg>
What is the use of these?
--disable-decoder=libdirac
--disable-encoder=libschroedinger
And does something speak pro/contra these?
--enable-libspeex (speech codec) [1]
--enable-libvpx (should speed up h264 decoding) [2]

Just wondering :)
