NAME
somagic-capture - Perform video capture with the Somagic EasyCAP DC60, Somagic EasyCAP002, or EzCAP USB 2.0
書式 SYNOPSIS
somagic-capture[OPTION]...
説明 DESCRIPTION
Initializes the Somagic EasyCAP DC60, Somagic EasyCAP002, or EzCAP ESB 2.0 registers and performs video capture.This program must be run as root in order to interact with the USB capture device directly.
オプション OPTIONS
-B, --brightness=VALUE
Luminance brightness control.The brightness VALUE must be between 0 and 255, inclusive.The default brightness is 128, which selects the ITU level.
-C, --contrast=VALUE
Luminance contrast control.The contrast VALUE must be between -128 and 127, inclusive.The default contrast is 71, which selects the ITU level.
-c, --cvbs
For the EasyCAP DC60 or EzCAP USB 2.0, use the CVBS (composite) input for video capture.For the EasyCAP002, use the numbered inputs for video capture. Different devices seem to have different numbering schemes, so try each input in turn to determine which one is correct. This is the default.
-i, --cvbs-inputVALUE
For the EasyCAP002 only. Select the numbered input to use.Different devices seem to have different numbering schemes, so the numbering may not match your device. Try each input in turn to determine which one is correct. The default input is 3.
-f, --framesCOUNT
Maximum number of video frames to capture.The default is -1, which allows unlimited frames.
--help
印刷プログラムの使用方法および使用例。
-H, --hue=VALUE
Hue phase in degrees.The hue VALUE must be between -128 and 127, inclusive.The default hue is 0.
--iso-transfers=COUNT
Number of concurrent iso transfers.Selecting a higher value might help alleviate sync artifacts.The default is 4.
--lum-aperture=MODE
Luminance aperture factor.The aperture factor MODE must be between 0 and 3, inclusive.Increasing this value can increase perceived sharpness.The default aperture factor is 1.
--lum-prefilter
Activate the luminance prefilter.This is bypassed (not active) by default.
--luminance=MODE
Luminance mode for the CVBS video input, selecting a center frequency in MHz.Does not apply to the S-VIDEO video input.The MODE must be between 0 and 3, inclusive.Decreasing the MHz value can increase perceived sharpness.The default is 0.

-n, --ntsc
Decode the NTSC-M video standard, which is used in North America.To decode the NTSC-J video standard, which is used in Japan, select -n along with -B 147 and -C 72.The internal vertical resolution is 525 lines. The output resolution is 720x480, which should be scaled to 720x540 for the correct aspect ratio of 4:3.The output framerate is approximately 29.97 Hz, or 30/1.001 Hz exactly.
--ntsc-4.43-50
Decode the NTSC-4.43 50 Hz video standard.The internal vertical resolution is 525 lines. The output resolution is 720x480, which should be scaled to 720x540 for the correct aspect ratio of 4:3.The output framerate is 25 Hz exactly.
--ntsc-4.43-60
Decode the NTSC-4.43 60 Hz video standard.The internal vertical resolution is 525 lines. The output resolution is 720x480, which should be scaled to 720x540 for the correct aspect ratio of 4:3.The output framerate is approximately 29.97 Hz, or 30/1.001 Hz exactly.
--ntsc-n
Decode the NTSC-N video standard.The internal vertical resolution is 625 lines. The output resolution is 720x576, which should be scaled to 720x540 for the correct aspect ratio of 4:3.The output framerate is 25 Hz exactly.
-p, --pal
Decode any of the PAL-B, PAL-G, PAL-H, PAL-I, or PAL-N video standards, which are used in many regions.The internal vertical resolution is 625 lines. The output resolution is 720x576, which should be scaled to 720x540 for the correct aspect ratio of 4:3.The output framerate is 25 Hz exactly.This is the default.
--pal-4.43
Decode the PAL-4.43 video standard, also commonly known as PAL 60.The internal vertical resolution is 525 lines. The output resolution is 720x480, which should be scaled to 720x540 for the correct aspect ratio of 4:3.The output framerate is approximately 29.97 Hz, or 30/1.001 Hz exactly.
--pal-m
Decode the PAL-M video standard, which is used in Brazil.The internal vertical resolution is 525 lines. The output resolution is 720x480, which should be scaled to 720x540 for the correct aspect ratio of 4:3.The output framerate is approximately 29.97 Hz, or 30/1.001 Hz exactly.
--pal-combination-n

--sync=VALUE
Sync algorithm. Selects the method used to decode the video and control information into frames of video.The sync VALUE must be either 1 or 2.The default is 2.
--test-only
Parses command-line options and performs capture setup, but does not initiate capture.The purpose of this option is to allow scripts to determine whether capture should be possible.
--vo=FILENAME

--version
Print the program version, the program copyright, a list of authors, and a notice that there is no warranty.
