sudo raspivid -t 0 -b 10000000 -w 1920 -h 1080 -fps 30 -n -o - | gst-launch-1.0 fdsrc ! video/x-h264,width=1280,height=720,framerate=30/1,noise-reduction=1,profile=high,stream-format=byte-stream ! h264parse ! queue ! flvmux streamable=true ! rtmpsink location=\"rtmp://10.1.1.68/live/stream\"```

## Stream video from generic USB camera

|
with gst, very cpu heavy
|
|
```
|
|
gst-launch-1.0 v4l2src ! image/jpeg,width=640,height=480,framerate=30/1 ! jpegdec ! x264enc ! flvmux streamable=true ! rtmpsink location="rtmp://10.20.86.88/live/stream"
|
|
```
|
|
|
|
with ffmpeg, cpu friendly
|
|
```
|
|
ffmpeg -f v4l2 -framerate 30 -video_size 640x480 -i /dev/video0 -b:v 2M -f flv rtmp://10.20.86.88/live/stream

(This can still be mitigated by enabling "old camera support" in the raspi-config settings. (This is done automatically in the postinstallscript)
