Dan, We do not use melt for rendering, only to determine which audio and video codecs are installed. We have a single video thread, that either hooks up to a sdl consumer for previewing or a avformat producer for rendering. So, I'm not sure if I need to add the NO_VDPAU flag. What would you suggest?
We have a bug report on LaunchPad explaining how to upgrade libsdl1.2debian to version 1.2.14. Other than that, we do not have much recommending that users upgrade. I was unaware that the sdl_preview consumer existed. =) You might have told me before, now that you mention it, but that sounds much better than the sdl consumer. I had noticed that sdl just never lets up on the CPU. I will see if I can't integrate the sdl_preview into version 1.1 of OpenShot, before we release it. Thanks for the feedback! -Jonathan On Fri, Feb 19, 2010 at 12:02 PM, Dan Dennedy <[email protected]> wrote: > Are you running melt or a separate child process to render?
