QUICK START GUIDE
-----------------

Make sure that the kernel headers are present.  On Debian the relevant
packages are called "linux-headers-...".  The command `uname -r` can be
used to find out which of these is the right one for your system.  When
installed the package populates /usr/src/linux-headers-X.X.XX-.../*.

Make sure the EasyCAP device is physically unplugged.  Then, as root:

Create a directory to work in:

mkdir ~/EASYCAP
cd ~/EASYCAP

Next, depending on where the file was downloaded to:

cp -p ~/Desktop/easycap_dc60.x.y.tar.gz .
tar zxf ./easycap_dc60.x.y.tar.gz
cd easycap_dc60.x.y
./install.sh

Check that the module has been successfully loaded:

lsmod | grep easycap

Physically plug in the EasyCAP device, and check that the following
special files have been successfully created:

/dev/easycap0
/dev/easysnd1

If you wish to perform the subsequent testing as an unprivileged user
you must give these special files the correct permissions:

chmod ugo+rw /dev/easycap0
chmod ugo+rw /dev/easysnd1

You may use the script ./permit.sh provided in the distribution to perform
this step if you wish.

If /dev/dsp is not present on your system install the package which
provides it.  On Debian the package is called oss-compat.  Optionally,
check that /dev/dsp has rw permissions for unprivileged users.

If all has gone well so far, check that the EasyCAP's input cables are
correctly connected to the videotape machine (or whatever) and test the
setup with mplayer.  Variations on the following command should give some
visible and audible output:

mplayer tv:// -tv driver=v4l2:norm=PAL_BGHIN:width=720:height=576:outfmt=uyvy:device=/dev/easycap0:input=0:fps=25:adevice=/dev/easysnd1:audiorate=48000:amode=1:forceaudio:immediatemode=0 -hardframedrop -vo xv -ao oss -msglevel all=9

A script test.sh is provided to make this easier.  You will need to remember
Mplayer's keybindings:  1 and 2 for contrast;  3 and 4 for brightness;
5 and 6 for hue;  7 and 8 for saturation;  / and * for volume;  m for mute.

If the test with mplayer is successful, you may wish to try using the
driver with other user programs, possibly using the supplied scripts:
               ./tvtime.sh PAL
               ./tvtime.sh NTSC
               ./vlc.sh PAL
               ./vlc.sh NTSC
It is necessary to have sox installed to provide the audio output for tvtime.
Because vlc must be run as an unprivileged user, it will be necessary for
root to run the script ./permit.sh in order to set the correct permissions
for /dev/easycap0 and /dev/easysnd1 after the EasyCAP is plugged in.  If vlc
fails to display a picture or shows a picture without colour, try editing the
file src/easycap.h so that line 41 becomes
         #define PREFER_NTSC      or     #undef  PREFER_NTSC
depending on whether you are using NTSC or PAL, then reinstall the driver.
