I am no expert with ffmpeg, but I could envision this not working with 3D apps on the 3D X server, because when you are using DRI to render OpenGL, the 3D pixels are bypassing the X server. Thus, it may be necessary to use Xvfb and VGL. It does seem inefficient, though, because you're reading back the pixels from the 3D X server, blitting them to the 2D X server, and reading them back yet again. Depending on the nature of the solution, it may be better to address the problem using a VirtualGL image transport plugin. ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
