This is an integrated audio/video driver for EasyCAP cards with
|
||||
USB ID 05e1:0408. It supports two hardware variants:
|

|
||||
* EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
|
||||
having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
|
||||
|
||||
* EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
|
||||
1, 2, 3, 4 and an unlabelled input cable for a microphone.

module will be called easycap

SUPPORTED HARDWARE
|
||||
------------------
|
||||
|
||||
This driver is intended for use with hardware having USB ID 05e1:0408.
|
||||
Two kinds of EasyCAP have this USB ID, namely:
|
||||
|
||||
* EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
|
||||
having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
|
||||
|
||||
* EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
|
||||
1, 2, 3, 4 and an unlabelled input cable for a microphone.
|
||||
|
||||
|
||||
BUILD OPTIONS AND DEPENDENCIES
|
||||
------------------------------
|
||||
|
||||
Unless EASYCAP_DEBUG is defined during compilation it will not be possible
|
||||
to select a debug level at the time of module installation.
|
||||
|
||||
|
||||
KNOWN RUNTIME ISSUES
|
||||
--------------------
|
||||
|
||||
(1) Intentionally, this driver will not stream material which is unambiguously
|
||||
identified by the hardware as copy-protected. Normal video output will be
|
||||
present for about a minute but will then freeze when this situation arises.
|
||||
|
||||
(2) The controls for luminance, contrast, saturation, hue and volume may not
|
||||
always work properly.
|
||||
|
||||
(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
|
||||
|
||||
|
||||
INPUT NUMBERING
|
||||
---------------
|
||||
|
||||
For the EasyCAP with S-VIDEO input cable the driver regards a request for
|
||||
inputs numbered 0 or 1 as referring to CVBS and a request for input
|
||||
numbered 5 as referring to S-VIDEO.
|
||||
|
||||
For the EasyCAP with four CVBS inputs the driver expects to be asked for
|
||||
any one of inputs numbered 1,2,3,4. If input 0 is asked for, it is
|
||||
interpreted as input 1.
|
||||
|
||||
|
||||
MODULE PARAMETERS
|
||||
-----------------
|
||||
|
||||
Three module parameters are defined:
|
||||
|
||||
debug the easycap module is configured at diagnostic level n (0 to 9)
|
||||
gain audio gain level n (0 to 31, default is 16)
|
||||
bars whether to display testcard bars when incoming video signal is lost
|
||||
0 => no, 1 => yes (default)
|
||||
|
||||
|
||||
SUPPORTED TV STANDARDS AND RESOLUTIONS
|
||||
--------------------------------------
|
||||
|
||||
The following TV standards are natively supported by the hardware and are
|
||||
usable as (for example) the "norm=" parameter in the mplayer command:
|
||||
|
||||
PAL_BGHIN, NTSC_N_443,
|
||||
PAL_Nc, NTSC_N,
|
||||
SECAM, NTSC_M, NTSC_M_JP,
|
||||
PAL_60, NTSC_443,
|
||||
PAL_M.
|
||||
|
||||
In addition, the driver offers "custom" pseudo-standards with a framerate
|
||||
which is 20% of the usual framerate. These pseudo-standards are named:
|
||||
|
||||
PAL_BGHIN_SLOW, NTSC_N_443_SLOW,
|
||||
PAL_Nc_SLOW, NTSC_N_SLOW,
|
||||
SECAM_SLOW, NTSC_M_SLOW, NTSC_M_JP_SLOW,
|
||||
PAL_60_SLOW, NTSC_443_SLOW,
|
||||
PAL_M_SLOW.
|
||||
|
||||
|
||||
The available picture sizes are:
|
||||
|
||||
at 25 frames per second: 720x576, 704x576, 640x480, 360x288, 320x240;
|
||||
at 30 frames per second: 720x480, 640x480, 360x240, 320x240.
|
||||
|
||||
|
||||
WHAT'S TESTED AND WHAT'S NOT
|
||||
----------------------------
|
||||
|
||||
This driver is known to work with mplayer, mencoder, tvtime, zoneminder,
|
||||
xawtv, gstreamer and sufficiently recent versions of vlc. An interface
|
||||
to ffmpeg is implemented, but serious audio-video synchronization problems
|
||||
remain.
|
||||
|
||||
The driver is designed to support all the TV standards accepted by the
|
||||
hardware, but as yet it has actually been tested on only a few of these.
|
||||
|
||||
I have been unable to test and calibrate the S-video input myself because I
|
||||
do not possess any equipment with S-video output.
|
||||
|
||||
|
||||
UDEV RULES
|
||||
----------
|
||||
|
||||
In order that the special files /dev/easycap0 and /dev/easysnd1 are created
|
||||
with conveniently relaxed permissions when the EasyCAP is plugged in, a file
|
||||
is preferably to be provided in directory /etc/udev/rules.d with content:
|
||||
|
||||
ACTION!="add|change", GOTO="easycap_rules_end"
|
||||
ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
|
||||
MODE="0666", OWNER="root", GROUP="root"
|
||||
LABEL="easycap_rules_end"
|
||||
|
||||
|
||||
MODPROBE CONFIGURATION
|
||||
----------------------
|
||||
|
||||
The easycap module is in competition with the module snd-usb-audio for the
|
||||
EasyCAP's audio channel, and its installation can be aided by providing a
|
||||
file in directory /etc/modprobe.d with content:
|
||||
|
||||
options easycap gain=16 bars=1
|
||||
install easycap /sbin/rmmod snd-usb-audio; /sbin/modprobe --ignore-install easycap
|
||||
|
||||
|
||||
ACKNOWLEGEMENTS AND REFERENCES
|
||||
------------------------------
|
||||
This driver makes use of information contained in the Syntek Semicon DC-1125
|
||||
Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
|
||||
by Nicolas Vivien. Particularly useful has been a patch to the latter driver
|
||||
provided by Ivor Hewitt in January 2009. The NTSC implementation is taken
|
||||
from the work of Ben Trask.
