Cannot view video from publisher using Chrome to iPad with OpenTok

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:

iPad view with 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.

Solution

  • 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.
