Status: RESOLVED DUPLICATE of bug 1182329

(Hello (Loop) :: Client, defect)

Description

[alex_mayorga]

¡Hola!

So as part of "Firefox 41 Beta 3 Testday, August 21st"[1] I tried a Hello call with satdav and the video was black initially for us both using Nightly.

My video eventually worked once I "Disable video" and then "Enable video" once.

For satdav video never worked and remained black the entire time.

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:43.0) Gecko/20100101 Firefox/43.0 ID:20150821030204 CSet: 095988abdc560bf8ba07a94a425c6922a3e9bfd6

alex_mayorga's camera is "QuickCam Pro for Notebooks"[2]

The Hello link is/was https://hello.firefox.com/Tfxwflo2U_w#2xXfv7TVE2i_Fxb8zOMJbg

¡Hola David!

http://trust.com/en/product/17405-primo-webcam says "For extra functionality download driver at www.trust.com/17405/drivers ".

Perhaps you need a driver update?

Same page also just lists "Windows 8, 7, Vista or XP" as "Minimum requirements" so perhaps it is not yet Windows 10 ready?

Just some thoughts but I think this bug lies on the Loop or Firefox side...

Please can you both try reproducing the issue on https://mozilla.github.io/webrtc-landing/gum_test.html with the Video + Audio button.

It might also be that we need to split this bug into two, as there seems to be different issues here.

¡Hola Mark!

Mystery solved!

I had to right click on the big black video then click on "Play"

Is this related to the fact that I "click-to-play all the tings"?

Do you have the media.autoplay.enabled set to false?
