I should have posted this in an new thread rather than burying it in the middle of someone else's. I've been fighting this for days. I have no live streaming, but I get still images.

There are a lot of "no live streaming" threads and I think I've read them all.

I "think" I've tried every fix and am still coming up empty. I guess it's possible I've tried the winning config changes along the way, but not in the right combination. I'm including what I believe are the relevant logs, configs and files below. Any hints would be GREAT!

I'm running ZoneMinder v1.34.22.
Ubuntu Server: VERSION="20.04.1 LTS (Focal Fossa)"
Annke C800 turret camera (now with Hikvision firmware)
source type: ffmpeg
function: Mcord
source is: rtsp://username:password@192.168.1.101:554/H264/ch1/main/av_stream

The above source works fine directly in vlc on a stand alone laptop. In other words, I can stream in vlc.

Here are my existing errors:

Did you try the "source" with VLC? The program not the Zoneminder option. If it works with VLC, check VLC (Tools, Media Information, Codec) to check camera Display Resolution. Then use that resolution in Zoneminder.
Do not edit any config files unless you use NGINX!!!
Also, what install instructions did you use for Zoneminder? Web server and database?

Thank you so much for the response. I won't be able to get back to this until sometime on Monday. I'll check the items you suggested and post an update. Thanks again!

Hi there. I have a similar issue and any help is appreciated.

All my cameras work except this one "6MP" Annke camera. And oddly, it worked when I first set it up, but it started just being a black screen that says "Unable to stream", and even odder all the recording are there I just can't access the stream live through zoneminder web portal, or through my ZM Ninja app, but I can watch the recordings in both.

In my VLC version 2.2.4, Tools > Media Information > Codec tab, I have

Type: Video
Codec: H264 - MPEG-4 AVC (part 10) (h264)
Resolution: 3840x2178
Display resolution: 3840x2160
Frame rate: 15
Decoded format: Planar 4:2:0 YUV full scale

I tried both these resolutions but still just "Unable to stream"

Anything stand out at an issue, or does anyone have any other troubleshooting tips?

I don't know if this is relevant or whether it will help to track things down, but it might.

On my system, ZM 1.36.5 on CentOS 7, the live and recorded views display the video in different ways - The recorded views use an HTML <video> tag but the real-time stream seems to be a continuously-updated JPEG image in an <img> tag.

Live stream:

Code: Select all

<img id="liveStream1" src="/cgi-bin-zm/nph-zms?scale=25&amp;mode=jpeg&amp;maxfps=30&amp;monitor=1&amp;auth=6e1b7837a981152a114f73d24419a154&amp;connkey=14671&amp;rand=67098" alt="" style="width: 487px; height: 274px;">

Recorded video:

Code: Select all

<video id="videoobj_html5_api" class="vjs-tech" style="transform: matrix(1, 0, 0, 1, 0, 0);" data-setup="{ &quot;controls&quot;: true, &quot;autoplay&quot;: true, &quot;preload&quot;: &quot;auto&quot;, &quot;playbackRates&quot;: [ 0,0.25,0.5,1,2,5,10,16], &quot;plugins&quot;: { &quot;zoomrotate&quot;: { &quot;zoom&quot;: &quot;1&quot;}}}" preload="auto" autoplay="" src="/zm/index.php?mode=mpeg&amp;format=h264&amp;eid=139994&amp;view=view_video&amp;auth=6e1b7837a981152a114f73d24419a154">
          <source src="/zm/index.php?mode=mpeg&amp;format=h264&amp;eid=139994&amp;view=view_video&amp;auth=6e1b7837a981152a114f73d24419a154" type="video/mp4">

I don't know why the image won't show for you, but this could be why you're seeing a difference between the live view and the recordings.

Thanks. I've been doing some digging and I found the same result. My zms logs (zms is the object used for live stream in the cgi directory of the path you showed and nph-zms is a symlink to the compiled zms binary) showed a floating point exception. Someone showed me how to set that objects debug level up to 3, and iconnor had asked for log level 3 data to troubleshoot. I got those logs and loaded them in the other thread and am hoping iconnor can help me figure out what's happening.
