Description Rohan Garg 2012-10-25 11:20:57 UTC 
Most VoIP clients horizontally flip the video stream so that the video stream shows the correct orientation of the user.

Reproducible: Always

Steps to Reproduce:
1. Start a video call
2. Raise right hand
3. Video window shows left hand being raised



In order to implement this we need to introduce the videoflip gstreamer element and set 'method' to GST_VIDEO_FLIP_METHOD_HORIZ

Additional info: G+ Hangout flips the image locally, but sends the original image.

I'm curious about skype. Can anyone try that?
Comment 2 Rohan Garg 2012-10-25 11:45:37 UTC 
Clearly G+ is drunk.
From what I remember Skype does flip the video.
Comment 3 Martin Klapetek 2012-10-25 11:49:12 UTC 
I think it's actually quite clever, because the other side will then see you mirrored - think of mirrored texts, having eypatch on left eye instead of right eye etc. So it's clever in that it shows you mirrored image locally, but the other side see you as they would see you in real life (ie. not mirrored).
