Questions[hd-video](ubuntu)

After installing Catalyst 11.12 and studying instructions (1, 2) to enable hardware acceleration I ended up with the following command:

sudo apt-get install xvba-va-driver libva-glx1 vainfo && \
vainfo && \
vlc --verbose 2 --ffmpeg-hw video.1080p.x264.mkv

The output confirms that it's using the VA API:

avcodec decoder: Using VA API version 0.32 for hardware decoding.

But even after a reboot the video still looks choppy. There's no vlc output to indicate that the codec is having trouble, or that it's skipping frames. Any idea what could be the problem?

Using vlc 1.1.12 with default settings.

Also tried (in sequence):

1. sudo apt-get install libva-glx1
2. sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core
3. Rebooting

No luck yet.

Specs from /proc/cpuinfo : Intel Core i7 CPU 950 @ 3.07GHz

When I watch a youtube video, especially in HD, the browser I'm using (chrome) will use in excess of 200% of the CPU. This causes the video to stutter and also makes my laptop very hot. Is it normal for it to use this much CPU? Also, it's even worse when I watch it fullscreen.

I'm on a Dell Studio XPS1645 with a first generation i7 and a ATI radeonHD 4670 graphics card (With the latest proprietary drivers). Running Ubuntu 12.04 (but the same thing happens with earlier versions). Also I'm using the HTML5 version of youtube as flash performs even worse..

Can anyone help me resolve this issue or at least tell me if this is normal?

Thanks

I have a Logitech C910 USB 2.0 USB camera which supports up to 1080p video recording. I am using the camera on a laptop with a Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz CPU. Ubuntu 11.10 recognises the device and allows me to capture both photos and video.

What does not work is high-resolution video recording: I haven't had much luck with anything above VGA resolution. Cheese appears to be hard-coded to use OGG which puts way too much strain on the CPU. guvcview crashes whichever way I try it.

Is it possible to record smooth, 25fps video at 1280x720px+ resolutions on Linux?

I have a 32" Vizio HDTV. It's a few years old, but running well. I just connected a new nettop to it using HDMI out. It's the Intel 3x00 graphics chipset.

I'm seeing overscan, where the resolution in Ubuntu is set to 1280x720, but the TV itself is 1366x768. When I go into the Monitors control applet, I cannot change the resolution to anything other than the current or 640x480.

A user had a similar overscan problem, but fixed the overscan by adjusting his TV's aspect ratio settings. I do not have that luxury.

Is there a way I can do this without having to delve into xorg.conf or other command-line craziness? I'm more than comfortable doing so, but there must be a cleaner way.

I'm running Ubuntu Natty, keeping up with updates and such.

When I try to watch a video with a high HD Resolution 1280 x 720 H264 in Ubuntu it isn't played smoothly. Stops and glitches occur. I don't think this is a problem with the CPU or graphics card, because under Windows there are no problems like this. Could it be a driver problem?

Update: For me VLC Player works best. No stops and no glitches. Smplayer also looks good but the performance leaks similarly to the standard Ubuntu video player in my case.
