Hi,

Firstly thanks for the nice jack options finding their way into MLT, they
are welcome indeed!

I have observed some problems in building recent 0.7.3GIT with jackrack
enabled. I develop AV Linux and have a whole host of audio related libs
within the distribution. I have observed in MLT builds with jackrack
enabled and 'dssi-vst' installed will result in melt segfaulting following
a dssi-vst scan. The scan is due to the recent ladspa identifying commits,
dssi-vst will allow Windows VST audio plugins to appear as ladspa plugins
so when melt launches and queries the system for ladspa plugins it will
include dssi-vst to scan them after which melt segfaults. Uninstalling
dssi-vst fixes the segfault.

Related to this is also an issue with Kdenlive and ladspa plugins (with
dssi-vst installed). When Kdenlive 0.8 is launched from the terminal MLT
will scan the ladspa plugins and end up in a terminal loop showing the
message 'librdf model not supported in this context'. After a delay of a
few minutes Kdenlive will finally launch. Since Openshot 1.31 is less
audio intuitive so seems to work fine and probably doesn't utilize
jackrack or ladspa so is not troubled by this.

I know these features are in early development but I thought I'd share my
findings so far. Building MLT with jackrack disabled works fine with both
Kdenlive 0.8 and Openshot 1.31 currently.

Thanks for your efforts, Glen MacArthur - AV Linux Maintainer
