I would like to know what to use in a google search for a program that transfers images from a video feed = an NT chart to a website sending screensnaps each 1/2 second. So I'm NOT looking to livelink my video of my NT screen but rather a program that samples the video taking screen snaps and uploads those screensnaps to a website.

(many years ago I did have one that uploaded my video cam to the website when the pipes were thin and it was for win 3.11 LOL I think it poled a memory location range and transfer that? )

First, you didn't put this in the NT category - I will move it for you.

Try this:


There are others also, but I'm having trouble remembering their names. Maybe someone else can assist. But the above one can programatically upload and save screenshots from NT, even making posts directly to FIO on a schedule or saving them in a directory.

I am pretty sure I tweeted or posted to facebook another new one, but can't easily find it right now as I am not in my office. Check our social media recent posts.

ChartMinder is great (thanks @gregid, I'm biased ) but you could also look at Jing et al, and some of the other screen sharing offerings, for example I seem to remember that Mikogo https://www.mikogo.com/ allows you to share a single application or window instead of a whole screen.

Cheers

So what I wish to do is to "continuously" upload screen-snaps that replace each other at the website creating the effect of streaming video. This would be like (but not equal to) an animated gif. The user would visit a webpage and within it was embedded a "live" streaming chart - on a 1/2 sec refresh cycle.

I use NT but I did not mean this as an NT only question - that is How to send any screen as a simulation of a video? - not specifically NT - which is why I didn't put it in the NT forum.

So repeating:
I am looking for the correct way to search on the internet for a program that continuously (say each 1/2 second) uploads images from a local machine to a webpage, each image replacing the prior one.

I am not looking for video conferencing or online presentation program.
It is NOT embedded video. If the connection between the local machine (that is pushing the images) and the webserver is broken, the last image served to the website would be there - not a blank.
The difference would be that is the server carries the workload of the traffic to any visitor to the page.

..........
peace, love and joy to you

That was it, sorry @ratfink I couldn't remember the name and wasn't in my office so it wasn't easy to search!

Too loud man.

Just try putting 'FTP upload' into Google. Actually just noticed Bing gives better results. Noted.

Fling from NCH looks like one of many solutions. Been years since I used any but there's a lot on the first page of that search term.

You didn't say whether you are handling web security/hosting issues which is why the conference solutions can make good choices. Also they use incremental upload protocols so traffic is negligible from your machine anyway, possibly even less than a repeating file upload.

Both routes should work alright.

Thanks.

(I'm not sure what too loud means.
that it isn't an nt specifiic question?
that upload a single image screensnap isn't what I am looking for?..
that the program from a users viewpoint you would specify
- what active window
- upload refresh time
- the ftp target

and it would continue without more user input until you stopped the program?)

Just use chart minder to capture the screen every 'x' seconds or whatever interval.

Then you can write a very simple script to just upload the most recent .png to your website (ftp for example).

On the HTML side, you can do a very crude meta http refresh to see the new image. Make sure you set all meta headers to disable caching if you aren't changing the filename, but just overwriting.

Obviously, far more complex solutions exist such as inline refresh via AJAX, or pushing directly from NT via a socket instead of scripting.

vvhg's solution has the built-in upload already there. Not sure about ratfinks.

The built-in uploads for both are FIO API specific.

I don't think vvhg's saved files on disk but CM does, so the FTP route works. I would probably add an option to allow same filename re-use instead of always creating a new time-stamped name.

As it happens I created a new version this weekend for a different user's 3rd party requirement that also allows arbitrary region/monitor grabbing so that would fit nicely. Release due this week.

Having the upload sorted (eg. with FTP) on the rendering side you could use this approach:

Here is what I have found so far.

It sounds as if it might do the job (reply 3 with the VBscript) but of course I don't know VBscript

Would this do the job?
-------------------the question -------------
"automatic screen capture + ftp?

I'm looking for a program that will take a screenshot at a specified interval and then upload that file to a ftp location. I've looked and after installing 8 different ones claiming to do what i'm looking for, i decided to come here and ask if someone knows a program that will do just that. i found one that is 500$ and that's way too much if you ask me.

thanks "
automatic screen capture + ftp? | Overclockers Forums
-------the reply ------------
"You are looking for 2 things, which are both freely available. This would be easier with open source software than it would be on windows, but its possible with simple scripts in windows with scheduled tasks.

Here is what you need:

1. save screenshot to a directory at set intervals
2. transfer files in a directory via ftp at set intervals

Yes, that's basically the approach I think would fit best but forget VB (I don't know it either.) I think maybe ChartMinder (but I may need to add the same filename option) and try Fling or similar for the FTP side.

Assumes you have a website setup and password credentials that you can use for normal website upload/updates.

I'm assuming Fling (or similar) can trigger just on detection of a new Windows directory/file modified timestamp.

New release due of CM can take images from any monitor/region independent of NT chart but might still be worth you looking at Jing or similar in case one of the commercial (and often free entry-level) products already has a built-in non NT dependent offering anyway.

We'll have a look this week. I'm best side of a decent Cab Sauv and some good telly. FIO rocks. I've got new socks.

So far I've

uploaded screensnaps with ShareX 11.3 and made the meta refresh page (both set for 5 sec intervals)


This morning I used ShareX to capture 10sec of screen action (I.mp4). The png shows as the same size 194kb

So I'm wondering about uploading 10 sec mp4 clips and then somehow have the webpage play those.

Is this a better way to go?

(I want to have a system where the screensnaps or mp4 are at the web server and served from there - not where the webserver is just a connecting link to my local machine (which is how I think the video conferencing works?)
