video played back from Printed QR code

[Smee]

I have been asked to find a qr code generator that will allow a printed QR code to be used to playback a video recorded on a ipad. Can anyone recommend an app please.

thx

Is this for a local video? Or like a YouTube one etc? If it's web based one can just use a normal URL and link to an auto-play link

its for a video the student will record on an ipad, the teacher then wants them to be able to print out the qr code and stick it in their books then to be able to scan it at a later date to play.

[Steve21]

Yeah but I mean once it's recorded on the ipad, is it staying on it? Or are you going to upload it somewhere? Else seems QR code would be a bit of a waste as you'd need that same ipad to get the video etc, or am I totally misunderstanding?

Nope I think your right, I will check with the teacher concerned exactly where she wants the video stored to and go from there. thanks for you help.........waste of time, in school? no never

I don't know of one, but it's a jolly good idea for an app - teacher or pupil takes a quick video, video uploads to nice secure central storage of some sort, QR code or whatever generated and sent straight to printer (or emailed to pupil / teacher) to be stuck in book / on wall.

I guess you could host the video on Google Drive or OneDrive, get a shareable link and then make the QR code point to the link.

Indeed - I'm working on something similar, it's a feature I could add. Just thought, though: no need to have print-on-demand QR codes printed individually via a label printer or similar, instead just print out (or buy) a batch of QR-code stickers in advance and have the video attach to a pre-done QR code you after you stick it in your book or wherever. Could even attach multiple videos, for groups. Hmm - it's such a good idea I can't belive someone else out there isn't already offering such a system, we just need to search a bit better!

Further update....The teacher would like the students to record a short video upload it somewhere and when anyone scans the QR code the video will play. Their idea is that there will be QR codes around school that anyone, visitors or students, will be able to scan with any device that has a QR reader and see the related video. I was hoping that we could use google drive or something similar to store the videos on but I'm having issues getting the app onto an ipad it just hangs. I had thought of icloud but can only share albums via URL not single video clips (unless I'm missing something) Any suggestions please. thanks

[Steve21]

If it's a visitor etc, best idea would be YouTube etc as I'm guessing they won't always be on your network? (Assuming the videos have permissions).

 

Then just do a QR to URL and set it to youTube link etc

 

If you didn't want it public obviously all devices would need local access wifi wise etc and then could just be held on a local webserver

The videos are just short clips that the students will be creating, something in the line of "this display was done by etc" The video won't be of any use to anyone off site. Another use was to do a quick book review then the QR would be used by students to see what others thought of the book. I think its just finding somewhere to store the videos and then being able to figure out the url so that we can make a QR code.

[Steve21]

I more meant in regards to if they're being hosted within your own network, then a visitor who uses their phone (4G) etc wouldn't be able to access it as it's a local link only.

is there any reason why I shouldn't use a youtube channel to store the videos on and then create the QR code with each videos URL? If I use the restricted option and make the channel "unlisted" I am hoping it can be kept secure. sorry for all the questions.

There are a number of reasons why not - they may or may not be surmountable for you. Video of students will count as personal data, so will need to be processed and controlled accordingly. You will obviously need permission from the students/parents. I've not recently looked at the T&C's for YouTube but I'd anticipate some potential issues there if the usual rights are granted as part of accepting the T&C's - I'm not sure how granting other parties substantial rights over distribution and use of that content sits with the need to have them act as a third party data processor (how would you get them to sign any data sharing agreement?). It is all very murky and difficult so probably most schools just stick their heads in the sand and just do it anyway.

If you are looking to just generate QR codes from a string that can be easily done. I use something like that to generate MFA Authenticator strings recently, not that anyone is using it yet but hopefully soon!

I did so using a NodeJS package called qrcode ( https://github.com/soldair/node-qrcode ) - this has some examples on the site. A simple node script that will return you a base64-encoded image is as follows:

 

if ( process.argv.length < 3 ) {
   return;
}
const string_to_encode = process.argv[2];

var QRCode = require( 'qrcode' );

return new Promise( function( resolve , reject ) {
   QRCode.toDataURL( string_to_encode , function( err , data_url ) {
       resolve( data_url );
   } );
} )
.then( function( data ) {    
   console.log( data );
} );

 

You can then run this using the following:

 

node ./your-script-name.js "some text goes here"

 

And then that will give an image which youcan display pretty simply, for example

 

...response from node script...

i.e.
data:image/png;base64,somebase64encodeddatagoeshere

 

I hope this is of help, if this sounds like it might help and you would like a hand then feel free to give me a shout and I can see what I can do about helping you getting this usable for you

 

edit: wow this forum destroyed the code formatting! hopefully fixed!
