Lightworks, PortAudio, and Opensuse Leap 42.2

I had some more messing about with PortAudio and Lightworks. This time I decided to build my own PortAudio as using a random build it silly.

Its easy after all: Download from:

Then if you build with:
./configure –enable-cxx=yes

then you can either make install as root (then check where it puts them might be the wrong place) or get the libraries out of the folders and dump them into /usr/lib/lightworks
libportaudioccp is in bindings/cpp/lib/.libs/
libportaudio is in lib/.libs/

Make sure you copy the sym links over too. It should then work without problems.

Lightworks 12.6 and PortAudio – Opensuse 42.2

I had a lot of problems with Opensuse Leap 42.2 and Lightworks. This time it was portaudio that was causing all the problems. It would either hang Lightworks when loading at the point portaudio tried to detected the audio interfaces. Or it would just be a mess of buffer overloads.

I fixed it in a weird way. I downloaded builds of libportaudio2 and libportaudioccp from Ubuntu, for the right architecture. I think unpacked them into /usr/lib/lightworks, which is where lightworks looks first for libraries. This worked, with one additional requirement that you have to use GlobalSettings.txt in your ~/Lightworks directory to make sure that portaudio uses pulseaudio as the interface. This avoids the buffer problems. Do all that and Lightworks 12.6 is happy on Opensuse Leap 42.2.

I am about to try Lightworks 14, see how that works before I pay for the upgrade.
