ACCELERATE HARDWARE

If Flash is using too much CPU power, the video or game play is "choppy," or the sound and picture are out of sync; you may try accelerating your hardware.

See what video card is on your system. Go to Menu --> System Tools --> LXTerminal (or Ctrl+Alt+T). Type (or copy and paste): sudo lshw -c video

Intel with the Intel 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
sudo sh -c "echo 'export VDPAU_DRIVER=va_gl' >> /etc/profile"
sudo mkdir /etc/adobe
sudo echo -e "EnableLinuxHWVideoDecode = 1\nOverrideGPUValidation = 1" | sudo tee /etc/adobe/mms.cfg

AMD with the radeon driver
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo mkdir /etc/adobe
sudo echo -e "EnableLinuxHWVideoDecode = 1\nOverrideGPUValidation = 1" | sudo tee /etc/adobe/mms.cfg

Nvidia with the Nvidia driver
sudo apt-get install libvdpau1 vdpau-va-driver
sudo mkdir /etc/adobe
sudo echo -e "EnableLinuxHWVideoDecode = 1\nOverrideGPUValidation = 1" | sudo tee /etc/adobe/mms.cfg

Reboot.

DISABLE HARDWARE ACCELERATION IN FLASH
In some cases, Flash's hardware acceleration does more harm than good. Disable it by right-clicking on any Flash video while it's running. Choose "Settings..."


Disabled Hardware Acceleration

Go to the first tab on the bottom of the dialogue box. Un-check the check box to "Enable hardware acceleration." Click the "Close" button.




Google Chrome web browser
Some DRM-protected online video streaming plays better in the Google Chrome web browser (64-bit computers only) than Firefox.



VLC

VLC: If you tried everything and video streaming over the Internet isn't working (well); you may not be able to receive and play video at the same time. This usually means you have a slow Internet connection and/or your computer hardware is simply too old. Try streaming videos through VLC (already installed), or download videos first (save them) and then play them later with VLC.
