Flash callback for allow button? about getusermedia.js

[shannon-fluellen-aurea]

Hey @rodfersou no worries, I ended up not needing this for the project anyway. Thanks for getting back to me though!

Hello? @addyosmani @franzenzenhofer @pablocubico @PhUU @rodfersou

[rodfersou]

@binarykitchen I think this button is managed by flash

[binarykitchen]

@rodfersou you think or are you sure? i really need a callback for when the allow button is pressed. otherwise my app will never know when the webcam is ready for recording. this is really important i must say. otherwise it's totally unusable for us.

[binarykitchen]

@rodfersou I think I found an example where you can see that there is a callback for when the user has pressed the allowed button in the Flash dialogue, see this line https://github.com/jhuckaby/webcamjs/blob/master/webcam.js#L583

So why not investigate this deeper and add this here too?

[binarykitchen]

And this link confirms that it's possible:

[rodfersou]

@binarykitchen nice!

[binarykitchen]

jhuckaby/webcamjs#96 (comment) confirms. Do you think you could add it please?

[rodfersou]

@binarykitchen how can I see this problem happen? could you plese provide me the steps? can I reproduce it with a linux machine?

[rodfersou]

@binarykitchen I'll try to look at it on my free time if you help me to see the problem happen

[binarykitchen]

how to reproduce? i recommend to begin with the face-detection-demo code. in the options at https://github.com/addyosmani/getUserMedia.js/blob/gh-pages/face-detection-demo/js/demo.js#L88

add a new event, for example onAllow: function() { ... } and have it fired when the user has clicked the Allow button.

the flash dialogue to ask whether to allow/disallow flash execution always shows. regardless whether you are on linux/mac/windows i think.

[rodfersou]

@binarykitchen did you test with what browser and what OS?

[binarykitchen]

Latest Firefox v39.0 on Ubuntu v15.04

[binarykitchen]

Any luck?

[binarykitchen]

@rodfersou ping???

[rodfersou]

I'm using firefox v39.0 in my Ubuntu, and it is not using flash when enable the camera.

Anyway, why don't you just look for the success callback to know that the camera is working?

It would be the same with or without flash.

[binarykitchen]

no, you don't understand - i am working on another library (https://www.npmjs.com/package/videomail-client) where i want to make it work for IE9+ too. i am looking for a library to encapsulate all the webcam communication plus all their events behind it.

this one library is almost a perfect match. all i need is an event to be triggered for when the user has granted the permission to access webcam. this regardless whether it's done via the getusermedia or via the flash path.

i need such a 'granted' event so that i can trigger someting else in the videomail-client for a very good reason.

i've seen other flash frameworks being able to catch and forward that event. so can you please add it?

hope this explains ...

[rodfersou]

@binarykitchen what I mean is that if don't grant access it will not trigger the success callback..

[rodfersou]

you can work with this

[binarykitchen]

i think we do not understand each other.

tell me, what callback is triggered then access is granted? there is no such callback at the moment.

[rodfersou]

success callback do it.

simple test: open the demo page and with chrome dev tools put a callback into success callback.

you will see that it will be triggered just when you allow to use the webcam

[binarykitchen]

i doubt this will do but i tried to run the demo and forced the flash with noFallback = false in google chrome. but it doesn't work there, the flash container never gets loaded and i am seeing the error Uncaught TypeError: Cannot read property 'code' of undefined.

cam.capture is always undefined. looks broken to me.

[shannon-fluellen-aurea]

@rodfersou @binarykitchen I'm running into the same problem with the flash execution path. The success function is never called and reading through the code, I'm having trouble seeing how it would be. I'm guessing somehow this

getUserMedia.js/lib/getUserMedia.js

Line 127 in a0f839a

options.onLoad = successCallback;

is what would do it but that event isn't triggering in Safari. Why would an options object like that have an onLoad event? Does it have anything to do with this?

getUserMedia.js/lib/getUserMedia.js

Line 125 in a0f839a

// options.onLoad();

Any help would be greatly appreciated!

@shannon-fluellen-aurea sorry, this issue is from 4 years ago... I'm afraid I can't help anymore with it because I don't remember and don't need anymore this code... I used it just in a simple project.

also, I'm out of free time now... good luck hacking with it!
