MJPEG Streaming on VLC

[DampSquib]

Hello All,

I've done quite extensive searching and testing without success.
So I'm asking for a bit of help.

1. I've got a Dahua IPC-HFW1230S-0360B-S5 camera.
2. I've enabled sub stream and set it to MJPEG (frame rate 15, bit rate 2304).
3. I've entered this string in VLC:
   http://CAMERA-IP/cgi-bin/realmonitor.cgi?action=getStream&channel=1&subtype=1
4. It gives me the login pop-up and I enter correct credentials

The stream never loads.

So two questions...

Is that string correct for MJPEG?

Is 'sub stream' on Dahua - channel 1, sub1? Or is it channel0?

You're web browser should display MJPEG natively.
If you're using VLC to view you're better off viewing a different type of stream unless it's just for testing purposes (I'm not even 100% certain VLC can play an MJPEG stream).

Thanks for the reply tangent, you're spot on - I was having a brain fart.
RTSP works fine in VLC, but I need MJPEG.
In a browser - all I get is:

Error
Bad Request!

Is Sub Stream here, Channel 0, Subtype 1 in strings?

Any ideas?

I've enabled sub stream and set it to MJPEG (frame rate 15, bit rate 2304).

1. I've entered this string in VLC:
   http://CAMERA-IP/cgi-bin/realmonitor.cgi?action=getStream&channel=1&subtype=1
2. It gives me the login pop-up and I enter correct credentials

there is no such thing as /cgi-bin/realmonitor.cgi over HTTP protocol..

there is: rtsp:/ /user: pass@192.168.1.108/cam/realmonitor?channel=1&subtype=1

(delete spaces from url)...

which works over RTSP protocol. This protocol is supported by VLC, not web browsers.

If You use this link in VLC (with correct user/pass/ip address) You will see secondary stream. Also in MJPEG version.

If You want mjpeg in browser, the only solution is to write java-script which will refresh every 1 second image loaded from:

http://user:pass@192.168.1.108/cgi-bin/snapshot.cgi

for that You don't need to configure mjpeg on second stream.

ps. I found one more link:

http://user:pass@192.168.1.108/cgi-bin/mjpg/video.cgi?subtype=1

Which will stream mjpeg over web browser.
Interesting in my cams this don't require to configure mjpeg on secondary stream.
But image quality is very bad (no dithering, big macro blocks)..

This works fine on my Dahua and Amcrest, using Brave (Chromium) browser:

http://user:passsword@192.168.200.205/cgi-bin/mjpg/video.cgi?subtype=1

Thank you all, I've got snapshots and streams working:
CAMERAIP/cgi-bin/snapshot.cgi?channel=1
