Hi,
I am using a tv card in a VM and get jerky video.As I understand it, the VM is using USB 1.1. However, when I set the USB controller in the BIOS of my server to Fullspeed (12 Mbit/s) which is the USB 1.1 speed I am able to get perfect results on the host but still on the guest the video is jerky.
There is a patch series from Hans de Goede on qemu-devel which adds buffering for isochronous usb transfers to the usb passthrough code. Certainly worth a try.
cheers, Gerd -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
