VDPAU and Window Manager on Jaunty Jackalope – Ubuntu 9.04

Today I did it. I’ve upgraded my system from Intrepid Ibex(8.10) onto Jaunty Jackalope (9.04). My Ubuntu x86_64 installation offered me, as always, a couple of new packages for update, and as I wanted to update, a message box told me, I could do a whole system upgrade onto Jaunty Jackalope. So I did and it worked. I took a very long time (>1h), but I had no unpleasant surprises afterwards.
All special sources.conf entries in my apt-get config have been commented out, and I started from scratch using a new Ubuntu installation.

VDPAU without tearing

I’ve reported several times about tearing with Nvidia’s new VDPAU driver. Now it seems I’ve found a working solution for me, to get rid of this pretty ugly tearing effect. Here are my steps:

  • Use latest driver (>=180.27) from the launchpad PPA repository. Add these lines into your /etc/apt/sources.list if you are using Debian/Ubuntu. If not, get Nvidias installer here: x86, x86_64 Continue reading

vdpau 180.18 now supports TwinView – sometimes

Nvidia released on 22th December a new vdpau driver, the version 180.18. Here’s the release note:
http://www.nvnews.net/vbulletin/showthread.php?p=1882835. To be honest, I didn’t suck out much of it. So I’ve tested the x86_64 version against my three notorious candidates, like I did before for [1,2,3,4,5].

  1. Matroska (.mkv) still stutter (jerky playback)
  2. Sync_to_VBlank is still being ignored -> Tearing
  3. TwinView is working! (almost)

VDPAU – The NVIDIA 180.06 beta driver for Linux – or how to play back AVCHD with GPU acceleration

[UPDATE] Read here about the latest development of NVIDIA’s vdpau video output driver: Tag: vdpau
I’ve been waiting for this moment a very long time, and honestly speaking, I didn’t really believe I would play AVCHD content form my Canon HF100 with hardware acceleration on Linux in the next future.

But today I did. Yes!

This is going to be a little HOWTO about installing NVIDIA’s new Beta driver 180.06 on a Ubuntu 8.10 (Intrepid Ibex).

Please consider this is all real Beta stuff, and it’s really not suitable for usage in a productive environment. I had more glitches, than successfull playback attempts, and the developers of NVIDIA don’t claim it’s a bullet prove application, like you can read it in this document: Continue reading

Tearing with nVidia drivers and mplayer with “-vo xv”

Well, let’s start with the conclusion: setting XV_SYNC_TO_VBLANK has no effect, if a second monitor is attached.

But let’s start at the very beginning: What is tearing? Well, this is how Wikipedia defines it:

Screen tearing is a phenomenon in video where a previously rendered frame overlaps a newly rendered frame, creating a torn look as two parts of an object (such as a wall) don’t line up…
