Rendering Headless with prman #1926

I'm trying to headless render a usd-file with the prman plugin using usdrecord:

$ usdrecord --renderer Prman ~/Kitchen_set/Kitchen_set.usd ~/out.jpg
qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Aborted (core dumped)

Is that even possible? And how could it be done?

usdrecord currently requires an OpenGL context to run, although we're close to removing that requirement (for non-GPU renderers like Prman). I'm not sure what's going on with the "qt" error messages, but I'm guessing when we're initializing GL we're generating those errors when we fail to create a context?

Just ran into this myself, has there been any update since July?

[hdx, usdAppUtils, usdImagingGL] Enable usdrecord to disable the GPU …
f92fd35 
…when generating images.

This mode is enabled by passing the "--disableGpu" option to the usdrecord.py script.  The GPU is enabled by default.  If no renderer is specified, an appropriate default will be chosen depending on whether the GPU is enabled or not.

Additionally, disabling the GPU will prevent the HdxTaskController from creating any tasks that require it.  In particular, this means that color correction is disabled when the GPU is disabled.  A warning to this effect will be emitted if color correction is requested in this case.

Fixes #1926
