1246348 - getUserMedia offers squeezed 320x240 image from Logitech C920

Status: RESOLVED DUPLICATE of bug 1180725

(Core :: WebRTC: Audio/Video, defect, P2)

Description

[bryandonnovan]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.103 Safari/537.36

Steps to reproduce:

pass video constraint {width:320,height:240} to getUserMedia and select the Logitech C920 USB webcam as the video source


Actual results:

Camera is initialized in 16x9 mode instead of 4x3 mode, resulting in a squeezed image


Expected results:

Display the correct aspect ratio, just as Chrome does

jib: ted has a C920, FYI, in case you need logs or something checked or a fix tested.
Ted: It would be interesting to see what mode gets selected for 320x240 (NSPR_LOG_MODULES=getusermedia:4,mediamanager:4,webrtc_trace:65535 WEBRTC_TRACE_FILE=nspr)

Testcase: https://jsfiddle.net/x6n4ny9q/

This works fine with my C920 on Windows, I haven't tried it on OS X yet. (I assume the reporter is experiencing this on OS X given the user agent in comment 0).

Here's an NSPR log with those settings from loading that jsfiddle and choosing my Logitech C920 on my Mac (Running 10.10.5).

Note: getusermedia/mediamanager logs are still missing... however, this is on mac (and the original reporter was too it appears).  Mac hides the "real" camera resolution, so we emulate size constraints.

jib, can you look?

It reproduces on my C910, and seems to be a problem on OSX only, i.e. works fine on Windows. https://jsfiddle.net/9t3szw0L/

This probably has something to do with us flying blind on OSX without bug 1180725. I'll debug to see if there's anything to do in this case.

Likely the same as https://code.google.com/p/chromium/issues/detail?id=303298.

Yes, it works for me now.
