814881 - getUserMedia fails

Status: RESOLVED WORKSFORME

(Core :: WebRTC: Audio/Video, defect)

Description

[jonathan chetwynd]

the getUserMedia example does not find a Sandberg NightCam 2 usb webcam that is known to connect
in Opera: http://auduno.github.com/headtrackr/examples/camshift.html 


tested using WebRTC Test Landing Page
with FF Nightly latest on OS X 10.6.8

So it looks like it's not a general problem with all webcams, as my integrated web cam works fine on that page. I'll have to check on with my logitech usb webcam when I get into work on Monday to see if it's USB vs. webcam specific.

Actually, I just tried a cheap USB webcam I have at home - works fine on that usb web cam as well.

#1 Jason the test is the mozilla URL given: http://mozilla.github.com/webrtc-landing/gum_test.html

my sandberg is known to work with the opera getUserMedia link given

it seems there is some confusion in the comms on this bug

Jonathan - Please don't change the title to something that's vague - it loses context behind what the problem is.

Jason are you using OS X?

> Jason are you using OS X?

No, I'm on Windows 7 64-bit.

Comment 7

[jonathan chetwynd]

well this bug was filed as OS X....

Comment 8

[jonathan chetwynd]

I have now checked on iMac with inbuilt camera and microphone running latest Nightly on OS X 10.8.2 .

whereas on mac mini the red text "NO_DEVICES_FOUND" is displayed, it is not on the iMac.

However afaict there is no evidence of any other i/o communication.

Obviously as there is no comment indicating what the expected and intended behaviour should be, it is hard for me to -know- the test has failed.

Using the Opera example, live video plays on connection, and this is as expected by me.

Don't write vague titles. Last time I'm saying this.

Comment 12

[jonathan chetwynd]

Jason, you'll need to write your own bugs in future.

do not reopen.

Comment 13

[Jason Smith [:jsmith]]

Jonathan - I was going off of what was specified in the bug description as we only confirm that the issue was happening on the USB camera you've specified on an OS X machine. getUserMedia broken tells us nothing about what the problem is. The title is usually changed to provide more context to what the problem is known to be. I'll be sure to check USB camera testing soon, so I'll end up testing this flow. But as it stands right now, I can't understand what your problem is.

Marking as incomplete.

iMac 10.8.2 running Nightly open url:

http://mozilla.github.com/webrtc-landing/gum_test.html

or http://www.gnote.org/dev.html 
wfm Opera & Chrome

try all 4 gUM test without any positive result 
no deny/allow
no lights
no images

also tested on mac mini OS X 10.6.8 with usb camera
similar outcomes.

Comment 17

[Jason Smith [:jsmith]]

I'm going to grab a mac machine and look into this to close out this hairy bug.

Comment 18

[Jason Smith [:jsmith]]

Just tried the gum landing page with a USB webcam and an integrated web cam on OS X 10.7. Couldn't reproduce this bug. Closing as a worksforme.

Comment 19

[jonathan chetwynd]

confirmed for iMac with integral camera on OS X 10.8.2

however this does not wfm external USB 10.6.8

Sandberg nightcam2 and PS3 eyecam

as clearly stated in description....

I am upgrading to 10.8, so will not be able to contribute to that aspect.

Comment 20

[jonathan chetwynd]

I can confirm that neither USB Sandberg nightcam2 nor PS3 eyecam wfm under 10.8.2

would like advice on how to reopen bug, 
as both wfm Google Chrome Canary Version 25.0.1353.0

Comment 21

[Jason Smith [:jsmith]]

Just to make sure (since I've made this mistake before) - Do you have preference enabled for media.navigator.enabled to true?

Comment 22

[jonathan chetwynd]

Today, I tested PS3 eyecam on debian wheezy using ff 28.0a1 (2013-11-18)

whilst the camera is recognised and raises a dialogue, no images are seen.
wfm fine on chrome etc..

tested on a wide variety of online resources including those mentioned above.

would appreciate any comments on how to test further.

Comment 23

[Randell Jesup [:jesup] (needinfo me)]

Use a debug build (download from ftp.mozilla.org/pub/mozilla.org/firefox/nightly)

set NSPR_LOG_MODULES=getusermedia:5
set NSPR_LOG_FILE=some temp file

then try it, and upload the log file to a new bug (in Core : Webrtc audio & video)

I suspect it's a camera that doesn't implement direct YUV in the type we need; chrome has translation functions that we haven't hooked up yet.
