Connects OK but no stream

Hi,

I am trying to use the mjpeg-relay to relay a IP camera mjpeg stream. When launching the streamer, everything is looking fine. The terminal looks like this:

I can see the to-be-relayed stream OK from the internet and on my local network. When I run the mjpeg-relay, I can see the status page and I do see a incoming bandwidth. When I connect to the /stream URL, I do see that the outbound bandwidth goes up. But 1. I do not see the mjpeg in the browser/-Tag. 2. Also VLC does not play the outgoing stream. I tried running the relay on a different server but makes no difference. Anything else I can look at?

Does the /snapshot url displays a snapshot? Can you paste the result of curl --raw -v http://localhost:54321/stream somewhere (I want to look at the headers).

My guess right now is that Transfer-Encoding: chunked confuses the parser.

strickerconsulting commented

No. The returning image is empty (also double checked wget - resulting file is empty)

Ok, give https://github.com/Silex/mjpeg-relay/tree/chunked-encoding-support a try and report.

Btw, in your above paste after the headers there's nothing?

My commit is based on http://docs.python-requests.org/en/master/user/advanced/#chunk-encoded-requests

Ah thanks.

Done that. When I run the relay now, it looks ok again, but the /status page show no incoming bandwidth..

Please use a pastebin or use github's code blocks.

Anyway, you are sure http://admin:****@dyndns-host:8091/mjpeg/stream.cgi?chn=1 works properly? Is it possible to setup some temporary viewer user for us to use?

Hello,

Just had a quick attempt, looks like that gives a 401 even when connecting directly without using mjpeg-relay. Please check the credentials

strickerconsulting commented
Silex commented

The credentials are fine, you need to use digest auth.

The problem is more like the camera only accepts very few connections... curl -v --raw --anyauth "http://test:test@dev.scw-services.com:8091/mjpeg/stream.cgi?chn=1" timeouts before sending the stream.

In all my attempts it only sent the MJPG once, and thus I could not debug.
