=Streaming with VLC from the command line=

==Logitech C910==
I've tried the Logitech C910, but it won't focus to infinity without an extra lens.

==Logitech C920==
The Logitech C920 still doesn't focus fully to infinity, but the picture is clear enough.

I have streamed to a site-local multicast address with transcoding, because the C920 gives a standard image format of yuy2, which isn't stream-able in a transport stream.
<pre>
cvlc -vvvv --v4l2-width=1920 --v4l2-height=1080 --v4l2-aspect-ratio=16\:9 --v4l2-fps=30 --v4l2-sharpness=255 \
--v4l2-power-line-frequency=1 --v4l2-set-ctrls={"009A090C=0"}--live-caching=150 v4l2:///dev/video0 --sout \
'#transcode{vcodec=mp4v,acodec=none,vb=12000,ab=0}:rtp{mux=ts,dst=239.255.255.45,port=5004,sdp=sap,name="localstream"}' \
--ttl 1
</pre>

There's also the possibility to stream without transcoding, but the following doesn't work well, because the webcam just isn't fast enough while building the mjpeg frames.
<pre>
cvlc -vv --v4l2-chroma=MJPG --v4l2-width=1920 --v4l2-height=1080 --v4l2-aspect-ratio=16\:9 --v4l2-fps=30 \
--live-caching=100 v4l2:///dev/video0 --sout '#rtp{mux=ts,dst=239.255.255.45,port=5004,sdp=sap,name="localstream"}' \
--ttl 1
</pre>

==BT878==
The following has worked for years with a BT878-based capture card:
<pre>
vlc -vvv v4l2:///dev/video0:input=1:width=720:height=576 --sout \
'#transcode{vcodec=mp4v,acodec=none,vb=2000,ab=0}:rtp{mux=ts,dst=239.255.255.45,port=1234,sdp=sap,name="test"}' \
--ttl 1
</pre>

==Edit Windows Default Playback Device with FFplay==
You can change the default playback channel (in Windows 10) by using the following environment variable.
The default setting is "Default playback device"
<pre>
set SDL_AUDIO_DEVICE_NAME=AirliteUSB5 (3- USB AUDIO CODEC)
FFplay
</pre>
