8.3. Stream with VLS
 | When you compile VLS, you must do a ./configure --enable-v4l --with-ffmpeg=PATH (where PATH si the absolute path to the directory where you compiled ffmpeg, and not the relative path !). |
There is no command line interface for this input for the moment... so you will have to use the configuration file.
Here is a typical configuration file vls.cfg for a v4l device :
# vls.cfg (VLS configuration file)
# Example of the VideoLAN HOWTO for the Video for Linux input
BEGIN "Inputs"
webcam = "v4l"
END
BEGIN "webcam"
# V4L device
Device = "/dev/video"
# Channel Source : Webcam is often "0"
# TV Card, may be Tuner(0), Composite(1), Svideo(2)
Channel = "0"
# Norm: PAL=0, NTSC=1, SECAM=2
Norm = "0"
# Size possibilities: can be either:
# - empty string : default size
# - width x height
# - subQCIF(128x96), QSIF(160.120), QCIF(176x144), SIF(320x240),
# CIF(352x288), VGA (640x480)
Size = ""
# DeInterlace: "0" = no ; "1" = yes
DeInterlace = "0"
# Video compression format: "mpeg1" or "mpeg4"
Compression = "mpeg4"
# Video bitrate (approx.) in kbps
Bitrate = "500"
# Quality: "1.0" (good) to "31.0" (bad)
Quality = "1.0"
# Sound device
AudioDevice = "/dev/dsp"
# Audio compression format: "mp2", "mp3" or "ogg"
AudioCompression = "mp2"
# Audio bitrate in kpbs
AudioBitrate = "64"
# Audio frequency ("16000", "22050", "24000", "32000", "44100" or "48000")
AudioFreq = "16000"
# Audio channel: "1" = mono ; "2" = stereo
AudioChannel = "2"
END
BEGIN "Channels"
channel1 = "network"
END
BEGIN "channel1"
# Unicast or multicast IP address
DstHost = "192.168.0.42"
# Destination port
DstPort = "1234"
# If it's a multicast IP address, uncomment the line below
#Type = "multicast"
# If it's a multicast IP address, set the "Time To Live" below
#TTL = "12"
END
BEGIN "LaunchOnStartUp"
command1 = "start v4l channel1 webcam"
END |
Once you have adapted the configuration file above, run VLS:
% vls -vv -f vls.cfg |
