I don't think you can with VLC.

[Rémi Denis-Courmont]

You can't do that, unless you're streaming with Secure RTP, or HTTP/TLS.

Thank you very much for your information, but how i can stream by SRTP?

[jeffreymu]

for CAS: i can stream using command
vlc -vvv t.ts :sout=#duplicate{dst=rtp{dst=239.255.1.1,mux=ts{csa-ck=ABBBBBBBBBBBBBBB},port=5004}}
however, i want to know how to stream by SRTP using 'srtp-key'? anybody would like help me, thx!

IIRC, you just need to set the srtp key and salt with the corresponding options.

[jeffreymu]

send stream:
vlc -vvv d:/t.ts :sout=#duplicate{dst=rtp{dst=239.255.1.1,mux=ts,port=5004,srtp-key=123456789ABCEF0123456789ABCEF0123456789ABCEF0123456789ABCEF0}} --loop
receive stream:
vlc -vv rtp://@239.255.1.1:5004 --sout-rtp-key "123456789ABCEF0123456789ABCEF0123456789ABCEF0123456789ABCEF0"

is it right above? but i can receive stream using command "vlc -vv rtp://@239.255.1.1:5004", so the secure RTP doesn't right? how to set the srtp key? thx!

Hello,

Could someone please provide a detailed description of how the server and the client need to be setup in Linux in order to stream encrypted webcam video using SRTP/AES? I cannot find a clear answer. Command line details are preferable.

Thanks a lot in advance,
SB

'vlc --sout-rtp-key HEXA_KEY --sout-rtp-salt HEXA_SALT' on the server.
'vlc --srtp-key HEXA_KEY --srtp-salt HEXA_SALT' on the client.
Then, it's just like normal RTP streaming.

Hello Remi,

Thanks a lot. Could you please kindly post a full command line example for the server and the client? (I am using VLC 1.1.4 (Ubuntu) and I want to stream my webcam (v4l2).
I think that such complete information would tremendously help people with the same request.

Thanks a lot once again for your help.
Cheers,
SB
