VLC uses this protocol (or access module) to read data from a device or network. |
module options
--v4l2-dev <string> Video device name (default /dev/video0) --v4l2-adev <string> Audio device name (default /dev/dsp) --v4l2-standard <string> Default, SECAM, PAL, NTSC --v4l2-chroma <string> Video input chroma format. The default is to auto detect. --v4l2-input <integer> Input of the card to use (0 is the default). Usually: * 0=tuner * 1=composite * 2=svideo --v4l2-io <string> Read method for the video. * READ = Basic read() * MMAP = Memory mapped buffer (the default) * USERPTR = User buffer pointer --v4l2-fps <float> Frame rate per second (0 = Unrestricted - the default) --v4l2-width <integer> Try picture width (-1 = auto detect) --v4l2-height <integer> Try picture height (-1 = auto detect) --v4l2-stereo <bool> Stereo audio (default true) --v4l2-samplerate <integer> Audio sample rate (default 48000) --v4l2-caching <integer> Caching value in ms
