[vlc-devel] The --vout options has been disabled on Windows

[David Robison]

I understand that forcing is not required, but the GPU affinity option I authored for VLC many years ago uses the nVidia OpenGL extensions. Without being about to specify the use of OpenGL then there is currently no way to set a GPU affinity. We have an application that displays multiple videos using VLC. Prior to this change we were able to support a larger number of simultaneous videos by spreading the load across multiple GPU. However, now we no longer have that ability. All I need is a way to make OpenGL the preferred VOUT instead of direct3d. Previously I used the --vout option to do that. From what you said, are you saying that it should be possible with the latest 3.0.0 code? David

Best Regards,

David R Robison
Senior Systems Engineer

I disagree, forcing the vout is no longer required. Since the embed-hwnd window module can now work with OpenGL and Direct3D vout.
