I am working on an app that uses WebRTC+WebGL. So far I've been using Nightly builds of Fennec and it's worked nicely but latest updates have broken it and I have to revert back to older builds. Here's a copy of my app as of yesterday: http://people.mozilla.org/~spenades/refapps/rtcamera/20130612/ It works nicely on Fennec's build of the 7th of june (once you enable WebRTC, that is), but fails in all sorts of weird ways with latest builds. Connecting remotely via port 6000 I get this kind of weird log: [12:59:37.705] NS_ERROR_FAILURE: Failure @ http://10.246.33.118:8000/js/rtcamera.js:257 -- [13:00:13.333] GET http://10.246.33.118:8000/ [HTTP/1.0 200 OK 140ms] [13:00:13.670] GET http://10.246.33.118:8000/css/x-tag-switch.css [HTTP/1.0 200 OK 29ms] [13:00:13.671] GET http://10.246.33.118:8000/css/shiftbox.css [HTTP/1.0 200 OK 33ms] [13:00:13.673] GET http://10.246.33.118:8000/css/style.css [HTTP/1.0 200 OK 50ms] [13:00:13.674] GET http://10.246.33.118:8000/js/libs/x-tags/core.js [40ms] [13:00:13.674] GET http://10.246.33.118:8000/js/libs/x-tags/shiftbox.js [HTTP/1.0 200 OK 70ms] [13:00:13.675] GET http://10.246.33.118:8000/js/libs/x-tags/switch.js [HTTP/1.0 200 OK 81ms] [13:00:13.675] GET http://10.246.33.118:8000/js/libs/glmatrix.min.js [HTTP/1.0 200 OK 186ms] [13:00:13.676] GET http://10.246.33.118:8000/js/libs/raf.js [HTTP/1.0 200 OK 102ms] [13:00:13.676] GET http://10.246.33.118:8000/js/libs/FileSaver.js [HTTP/1.0 200 OK 116ms] [13:00:13.677] GET http://10.246.33.118:8000/js/libs/Animated_GIF/omggif.js [HTTP/1.0 200 OK 359ms] [13:00:13.677] GET http://10.246.33.118:8000/js/libs/Animated_GIF/NeuQuant.js [HTTP/1.0 200 OK 352ms] [13:00:13.678] GET http://10.246.33.118:8000/js/libs/Animated_GIF/Animated_GIF.js [HTTP/1.0 200 OK 188ms] [13:00:13.679] GET http://10.246.33.118:8000/js/libs/Hammer.js [HTTP/1.0 200 OK 674ms] [13:00:13.679] GET http://10.246.33.118:8000/js/ImageEffect.js [HTTP/1.0 200 OK 264ms] [13:00:13.680] GET http://10.246.33.118:8000/js/Renderer.js [HTTP/1.0 200 OK 503ms] [13:00:13.681] GET http://10.246.33.118:8000/js/rtcamera.js [HTTP/1.0 200 OK 692ms] [13:00:13.683] GET http://10.246.33.118:8000/img/icons/ic_action_cancel.png [HTTP/1.0 200 OK 1179ms] [13:00:13.684] GET http://10.246.33.118:8000/img/icons/ic_action_done.png [651ms] [13:00:13.684] GET http://10.246.33.118:8000/img/icons/ic_action_video.png [576ms] [13:00:13.685] GET http://10.246.33.118:8000/img/icons/ic_action_photo.png [HTTP/1.0 200 OK 5153ms] [13:00:13.888] GET http://10.246.33.118:8000/img/icons/icn-coachmark-press.png [HTTP/1.0 200 OK 6225ms] [13:00:13.889] GET http://10.246.33.118:8000/img/icons/icn-coachmark-arrows.png [HTTP/1.0 200 OK 6735ms] [13:00:13.890] GET http://10.246.33.118:8000/css/fonts/Roboto-Regular.ttf [HTTP/1.0 200 OK 1090ms] [13:00:13.890] GET http://10.246.33.118:8000/css/fonts/Roboto-Condensed.ttf [HTTP/1.0 200 OK 1574ms] -- [13:00:27.692] ReferenceError: xtag is not defined @ http://10.246.33.118:8000/js/libs/x-tags/shiftbox.js:4 The line 257 in rtcamera.js is something as innocuous as canvas.width = canvasWidth; xtag is indeed loaded (no 404 in x-tags/core.js!) but for some reason the browser refuses to parse it. Sorry for not being able to provide with more details, but even trying to debug this step by step is pretty hard. I don't know if it's because of Nightly or what, but I cannot even set a breakpoint and try to determine what the values of things are when the weird NS_ERROR_FAILURE happens.

So I managed to do a little bit of adb LogCatt'ing. This time I am using the Nightly from 10th of June, which is broken too! :-( The log starts before I tap on the recent website (it being the test url for my app), shows the weird NS_ERROR_FAILURE and some captures frames, then I press back and the log ends. Hope it helps? Please let me know if you need any more info.

Just in case it helps, this is the output of logcat when running 7th June Nightly. This is a successful app run, in that no weird errors happen, and I get to display the Camera output using WebGL. Actions are the same: go to the recent website, accept sharing back camera, display a few frames and back.

I have a suspicion this is something outside the webrtc code, but to verify, can you go to http://mozilla.github.com/webrtc-landing/gum_test.html and verify the getUserMedia works on your phone? Thanks

I can confirm that your test page works both on Nightly 7th June and on Nightly 13th June.

The error seen in this test app is also happening on desktop. When checking the logs, I'm seeing this failure happen around the canvas area of code.

Confirmed this is working on 6/7/2013, broken on 6/12/2013. Working on getting a range now.

Last Working: 6/9/2013 First Broken: 6/10/2013

I'm pretty sure this is a WebGL regression, not a WebRTC regression.

Jeff - The recent push logs show that you've made changes recently to the WebGL codebase. Do you have any ideas on what caused this regression?

This sounds like bug 881681. It should be fixed in today or tomorrow's nightly.

Soledad - Can you retest this on tomorrow's nightly?

I've updated Nightly to the latest (14th of June) and... it works! \o/ Good work, friends :-)
