Hi,

I have a webcam connected to my laptop. I'm using RTSP H.264/AAC (TS) to stream to my Android phone. VLC uses lots of CPU to stream. I assume it's constantly encoding the webcam video to H.264.

I want the encoding to only start when my client (phone) connects. I don't want it otherwise encoding 24x7.

Is this possible? If so, how?

Thanks,
John

You need to set up your webcam as Video on Demand instead of broadcast. I'm using Windows so:

Here's how I did mine (I'm using the HTTPd interface):

Code: Select all

vlc.exe --ttl 12 -vvv --color -I http --rtsp-host 0.0.0.0:554

and used the following VLM commands:

Code: Select all

new cam vod enabled
setup cam input "dshow://"
setup cam output #transcode{vcodec=mp4v,vb=230,fps=24,width=160,acodec=mp4a,ab=32,channels=1,samplerate=32000}
setup cam option dshow-vdev="QuickCam Pro"

Set dshow-vdev to whatever your camera id is. You might also need to replace the transcode options for your phone.

Using these settings, VLC will only start my cam when I connect to it from my phone (rtsp://xxx.xxx.xxx.xxx:554/cam) which I think is exactly what you're looking for. Hope that helps and good luck.

Thank you so much!!! You are so kind for responding. This is exactly what I want to do. It will take some time for me to get this working, but I'll figure it out.

THANK YOU!
