Upgrade from 1.34 to 1.36 - no longer able to click on remote rtsp cameras in Montage Review to show passthrough display

[klui]

Some background. I found out 1.36 was available a couple of days ago and upgraded on Ubuntu 18.04. It was difficult as remote monitor rtp/rtsp broke and I needed to use rtp/unicast. Performance was poor and I had to change my camera system's streaming fps so my cameras all display in Montage Review.

I have it mostly working like 1.34 but when I use Montage Review in 1.34 I typically click on a camera in Montage Review and a new window pops up that shows the stream with higher fps rates. Under 1.36 if I click on a camera I get a display where it says "No matching records found."

I don't want to save the cameras' stream on disk to review, I want to see the current camera's stream in a higher frame rate. Is this possible under 1.36?

So that's a little weird, it is not doing that for me and it's the first report we've had of it. So let's dig in.

First off, what version of 1.36? You should be up to latest 1.36.31.
Second, let's be clear are you watching live view vs historical? Based on your words it sounds like yes, but let's be clear. Because click on a camera in live view should take you to the live watch view for that camera, but in historical mode it should take you to the event for that moment.

The No matching records found sounds like it is coming from boot-strap table which makes me think we are looking at an events list... but montage review doesn't have any links or code to go to the events list.

I should say further that unless you are streaming from a jpeg snapshot source, you should transition to using the ffmpeg monitor type.

Thanks for the reply. I never got notification through email and I just checked this thread.

I am on 1.36.31. I upgraded directly from the latest 1.34.x to 1.36.2x(?) through apt dist-upgrade. The following day I did another dist-upgrade because the VM was not responsive and went to 1.36.31. Maybe the initial upgrade didn't go according to plan?

I tried changing one of my camera sources to ffmpeg but it didn't help with the issue I'm experiencing although the camera does capture and I see the slower stream in montage.

My config for one camera. The resolution of the stream is actually 704x480 but if I change the capture resolution to that the monitor doesn't capture. It only works if I set to 720p.

When I go to Montage Review (/zm/index.php?view=montagereview; I have web_compact_montage checked in Options > Web) I see all my cameras and if I open inspector, here's what it says for that table.

Code: Select all

<div id="monitors" style="height: 378.433px;">
<canvas id="Monitor3" title="3 QS-1-fd" style="border: 1px solid rgb(0, 0, 0); position: absolute; left: 0px; top: 0px;" monitor_id="3" width="238" height="134">No Canvas Support!!</canvas> (event) ... 

Here's (event)

Code: Select all

function clickMonitor(event) {
  var element = event.target;
  //var monitor_element = document.getElementById('Monitor'+monId.toString());
  var monId = element.getAttribute('monitor_id');
  var pos_x = event.offsetX ? (event.offsetX) : event.pageX - element.offsetLeft;
  var pos_y = event.offsetY ? (event.offsetY) : event.pageY - element.offsetTop;
  if (pos_x < element.width / 4 && pos_y < element.height / 4) {
    zoom(monId, 1.15);
  } else if (pos_x > element.width * 3 / 4 && pos_y < element.height / 4) {
    zoom(monId, 1 / 1.15);
  } else {
    showOneMonitor(monId, event);
  }
  return;
}

Clicking on the image, I get redirected to /zm/index.php?view=watch&mid=3. The display looks like the attached screenshot.

Interestingly if I go to Montage, I get this

I was trying the site using Microsoft Edge instead of Firefox and I got a "This plug-in isn't supported" in the live stream. Here's the feed definition

Code: Select all

<embed type="video/jpeg"

The solution is in the B/W Options I need to set WEB_H_CAN_STREAM to "yes" from "auto." Now things (stream using MPEG/JPEG) work for both Firefox and Edge. Normal Montage works as well.

Ok, I understand what's going on now. Sounds like you've solved it.

I need to rip all the old embedded aplet stuff out. No modern browser supports it anymore.

I will look into the 704x480 not capturing thing.... there can be issues when the width isn't divisible by either 16 or 32 or whatever. SOmetimes changes with ffmpeg version.
