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 0 => testcard bars when incoming video signal is lost - 1 => testcard bars when incoming video signal is lost (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. - -This driver does not understand the V4L1 IOCTL commands. - - -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.
