FMLE.app works but FMLECmd does not

Dear Lazyweb,

How can it be ts the GUI of FMLE is able to connect and stream video, but the command line version, running with the same XML file and as the same user, cannot?

These error-looking farts in FMLECmd's output (shared memory, mach ports, command not found) do not occur in the log when the GUI runs.

Streaming to Primary...
[ ... and then it doesn't encode anything. ]

Also: how do I set the output frame rate? It is changing the resolution just fine, but if I set the frame rate to anything but 60, I get "an unexpected encoding error occurred" every 30 seconds, and it drops and reconnects.

Is there any non-GUI alternative to FMLECmd that runs on MacOS?

Graphics Generated by Levitated and Animated Objects in a Computational Acoustic-Potential Field

This novel graphics system is based on expansion of 3D-acoustic-manipulation technology. In the conventional study of acoustic levitation, small objects are trapped in the acoustic beams of standing waves. Here, this method is expanded by changing the distribution of the acoustic-potential field (APF), which generates the graphics using levitated small objects. The system makes available many expressions, such as expression by materials and nondigital appearance.

In the current system, multiple particles are levitated together at 4.25-mm intervals. The spatial resolution of the position is 0.5 mm. Particles move at up to 72 cm/s. The allowable density of the material can be up to 7 g/cm^3. This study used three options for APF: a 2D grid, high-speed movement, and a combination with motion capture. They are used to realize floating-screen or midair raster graphics, midair vector graphics, and interaction with levitated objects.
