Automation Professionals' Image Streamer Driver Module

nminchin · January 27, 2021, 11:06am

Cheers, do you know when it will be released?

And can it do this, though?

pturmel · January 27, 2021, 1:05pm

It is not at the top of my to-do list, sorry. It is being used in production, even with the leak. I'm happy to sell you a license if you've tested it for your needs.

I have no test hardware with that auth problem, so I don't know. The module uses OpenCV's URL handling, not java's, so there's a reasonable chance it'll work.

nminchin · January 27, 2021, 1:07pm

Cool, I’ll give it a test onsite and see if I can get it working with their equip and get back to you.

Keep in mind that stream processing is a major CPU hog–enough to disrupt other Ignition operations if you use this on a wimpy server. The current major production user (the development sponsor) runs it on a separate Ignition VM instance with just the OPC-UA Server license ($150).

Maybe try running that in a loop until it comes up with something that doesn’t cost $1000 more for installations that use none of those drivers!

pturmel · February 17, 2021, 7:23pm

Significant impact on hub-and-spoke architectures that only need one of the major branded drivers. Or none of the branded drivers, like this case. Everyone will get the “Ultimate” package’s driver collection, at the “Pro” price, even if they only need “Basic”. ):

Also protects IA from a small revenue loss if my Modbus Server module becomes popular, since it includes client functionality. Pushback to encroachment on IA functionality isn’t really a surprise.

If you need “Pro” or “Ultimate”, this is a nice feature upgrade and/or price cut. (:

I think that nets out to |:

Kevin.Herron · February 17, 2021, 9:43pm

If I were a 3rd party driver developer I’d be abstracting away as much of the Ignition-specific stuff as possible and producing 2 artifacts: a module for Ignition and a stand-alone OPC UA server + driver.

If you develop for the new driver API in 8.0 you’re probably 80% of the way there. The only meaningful functionality provided by Ignition is UI and persistence for configuration values.

pturmel · February 17, 2021, 10:01pm

Well, I only have three drivers, and only the Modbus driver is very "pure" from an OPC viewpoint. And its most important feature is exposing data to external Modbus clients. Not really something that makes sense for a stand-alone OPC server. This image streamer driver is only incidentally an OPC driver--its core functionality depends on the platform's web technology. Java's not really a first choice for stand-alone video stream conversion servers...

Kevin.Herron · February 17, 2021, 10:02pm

Yeah I was thinking more for your ENIP and Modbus stuff.

pturmel · February 17, 2021, 10:04pm

There’s other work in progress on the ENIP stuff… can’t say more yet. (:

josborn · April 5, 2021, 11:05pm

I just discovered your module today, and its great! I’ve been looking for a solution the the ip camera viewers inability to use rtsp forever. You mentioned it can be CPU intensive, but is that if you have many OPC UA ReStreamer device connections, or more so if you are actually viewing multiple streams?

pturmel · April 6, 2021, 1:42am

It is a cpu hog on a per-incoming-stream basis. It is very efficient for many consumers of a single stream.

josborn · April 6, 2021, 1:52am

I am looking at this as a possible way to replace an old allegiant switcher, so i would have tons of devices, but only a hand full of active streams. In this case is it a cpu hog, even if the majority of streams are not being used?

pturmel · April 6, 2021, 9:43am

Yes, the decoding of a 1080p 30fps stream, even when not used, will consume about 1/2 a modern CPU core. The corresponding full-scale output MJPEG-encoded stream to one or more viewers will consume another 1/2 core, but only while a viewer is connected. Half-scale and quarter-scale output streams are much less demanding.

You could try enabling and disabling devices via script to reduce load when you know that no viewers are watching a particular device.

josborn · April 7, 2021, 2:38am

I tried the enable/disable via script idea, but the delay on enabling is too long for my purposes. I don’t know if it fits with your design goals, but you may consider also including a fps parameter in addition to the half and quarter scale(assuming its possible). I can set the stream fps on the camera, but its universal and also affects the recording. While your module may not fit my purposes, its still excellent, thank you!

pturmel · April 7, 2021, 11:20am

It's not possible with OpenCV's VideoCapture() class. Settting it at the camera is the only option.

That error tends to show up when OpenCV has been successfully installed, but OpenCV can’t find your ffmpeg DLLs. Make sure you followed the instructions for ffmpeg, too, and included it in the path.

Edit: Actually, that shows up for true connection errors, too (url typos, etc). OpenCV doesn’t provide error codes for more detail, unfortunately.
