# Stream Video

```
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
