CrystalHD drivers for Linux

Preperation:
Install the required build tools first.

equo install autoconf


1) Get the source. Get the driver source code from the git repository.

git clone git://git.linuxtv.org/jarod/crystalhd.git

2) Fix the source. You can apply it by going into the main crystalhd source directory and doing

Download the patch from
https://drive.google.com/file/d/0ByyLo2VHCtYpOC1rT0d0NFZ1VHc/edit?usp=sharing
patch -p0 < devinitFix.patch

3) Compile driver, install libraries, and load driver.

Use make command to compile driver. If you have multiple core processor then use the "-j2" or "-j4" option (2 or 4 is the number of cores). This will speed up the make process.

cd crystalhd/driver/linux
autoconf
./configure
make -j2
sudo make install

Install the libraries.

cd ../../linux_lib/libcrystalhd/
make -j2
sudo make install

4) Load the driver.

sudo modprobe crystalhd

5) Make it autoload at startup

nano /etc/modules-load.d/crystalhd.conf 

and add

# Load crystalhd.ko at boot
crystalhd

6) Reboot your system, then check if 'crystalhd' is listed in the output of the following commands.

lsmod
dmesg | grep crystalhd

7) Although the latest flash (11.1.102.55-1) supports crystalhd out of the box it won't be enabled until you edit /etc/adobe/mms.cfg so that it has:

EnableLinuxHWVideoDecode=1
OverrideGPUValidation=true
