Alternative Idea #990
Updated by Hammel over 1 year ago
In order to provide support for RTSP only cameras (which are higher end but better quality), the following script can be used. It just requires a properly build ffmpeg and the v4l2loopback kernel module to convert the RTSP stream into MJPEG, which could then be streamed via mjpeg-streamer. It creates /dev/video2 and /dev/video3 as separate video devices but there is only one ffmpeg streaming to /dev/video2 (/dev/video3 is not used in this example, but could be to create multiple mjpeg streams for the same camera.
<pre><code class="shell">
#!/usr/bin/bash
CAMERA_IP="192.168.101.47"
RESOLUTION="1280x720"
# List video devices
echo "Video Devices:"
ls -1 /dev/video*
# Create a virtual webcam
sudo modprobe v4l2loopback devices=2 video_nr=2,3 max_buffers=2 card_label="QSC PTZ" exclusive_caps=1
echo "Video Devices:"
ls -1 /dev/video*
sleep 2
# Streams a remote RTSP camera to virtual webcam.
ffmpeg -rtsp_transport tcp -protocol_whitelist rtp,file,udp,tcp -stream_loop -1 -re -i rtsp://${CAMERA_IP} -f v4l2 -vf format=yuv420p -vcodec mjpeg -s ${RESOLUTION} -threads 0 /dev/video2
# Remove the V4l2 loopback module
sleep 2
sudo rmmod v4l2loopback
</code></pre>
It seems this could be an extension to the current webcam request by adding MA_RTSP to MT_STREAM.
