If you are using a system fffmpeg it can conflict with the ffmpeg internal snapshoot. But i think this problem is related to undefined weak symbol in the ffmpeg library. This cannot be accurately sorted when using static linking.
My pov is that static linking should be avoided. It is always better to build a shared version even if it is meant to be internal to cinelerra (using a --suffixed SONAME in ffmpeg) > Is it still an issue to have an external copy of ffmpeg installed?
