ffmpeg-4:0.6.1-5 and jack support

[Dragan Noveski]

hallo,

i am an aptosid user and using the ffmpeg-4:0.6.1-5 on my system.
if i am looking right, this version is compiled w/out jack support.
is there any special reason, or has the jack support just been forgotten 
while preparing the package?
if there is any chance to include jack support in ffmpeg i would be more 
than happy.

anyway, thanks for your work and maintaining all this complicated stuff!

cheers.
