I'm running Ubuntu 14.04 on an Acer Aspire V7 (i7 Haswell CPU). Playing any kind of movie file mkv, mp4 etc on VLC or Totem is horribly choppy with very slow frame rate like the computer can't handle it properly. Weirdly though playing the same files in Firefox using the VLC plugin works absolutely fine. What's going on here?

I've been having similar issues with VLC lately in 14.10. I use firefox with no plugin (all disabled) and mp4 plays fine as well. Switching to parole media player seems to work just great but not as many options as VLC (playback speed etc).

One thing you can do for your intel chip is to first install vdpaudrivers http://www.webupd8.org/2013/09/adobe-flash-player-hardware.html and in your vlc settings there is an option for hardware acceleration. make sure that box is selected and you can even specify to use the VDPAU va gl acceleration if i'm not mistaken.

Here's how to install the drivers:

sudo apt-get install i965-va-driver
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install libvdpau-va-gl1

Another way to run VLC with hardware acceleration is to use the following command (after installing the drivers):

VDPAU_DRIVER=va_gl vlc

or

VDPAU_DRIVER=va_gl totem

or

VDPAU_DRIVER=va_gl parole

It also helps to install the intel-linux-graphics installer. You can do that with the following commands:

wget https://download.01.org/gfx/ubuntu/14.04/main/pool/main/i/intel-linux-graphics-installer/intel-linux-graphics-installer_1.0.7-0intel1_amd64.deb
sudo apt-get install gdebi
sudo gdebi intel-linux-graphics-installer_1.0.7-0intel1_amd64.deb
sudo apt-get -f install
sudo intel-linux-graphics-installer

Finally, it really doesn't hurt (it helps) to have all the opengl support you can find. The synaptic package manager can help you search for and locate opengl packages. Just pay attention to what get's uninstalled if anything and never accept changes before reviewing to make sure installing stuff isn't going to uninstall something important in the process.
