Cannot view video from publisher using Chrome to iPad with OpenTok

Question

I'm currently trying to set up a connection between my web client and my iOS app, but for some reason my iOS client only sees a black box when using Chrome (version 33). I can see the video just fine if I use Firefox (both in my app and when I put the browsers side-by-side, they can see each other).

This doesn't appear to be a documented known issue with the JavaScript SDK, and I can't see any recent discussion about this on the forums (last post was mine).

The iOS sample can be located here (samples/OpenTokHelloWorld) with the browser page in samples/OpenTokHelloWorld/browser_demo.html

I suggest cd'ing into samples/OpenTokHelloWorld and running python -m SimpleHTTPServer, as it can't be run from a file:/// path.

Here is what my iPad sees:

Chrome:

Firefox:

And Chrome/Firefox (respectively), both publishing video from the same camera

Edit: after testing on other machines, it may be something specific to my environment even though none of my extensions run in Incognito and I don't have any custom plugins installed.

Answer 1

It looks like the OpenTok mobile SDKs with the specific webcam I was using has issues. On Android the video stream will display for a brief moment then segfault, and on iOS there will be no video at all.

Answer 2

I have tested this many times and could not reproduce what you are seeing in your chrome. Without seeing any console errors or iOS logs the best suggestion is to try clearing your cache, or maybe restarting your computer (longshot)
