How to play *.MOV videos in correct orientation?

[thoste]

With my digicam I recorded a video in protarit mode.

After loading it into QuickTime Pro I rotated it by 90 deg and saved it.

From that time this *.MOV video is shown in the correct oriantation in QuickTimePlayer.
Unfortuantely this is NOT the case in VLC. Here it is still in portrait mode shown in VLC.

Why?

How do I have to tell VLC: "Look into the header of the *.MOV video for the correct orientation"

That would not make much sense. The video rendering API that VLC uses to get to the video overlay hardware don't allow rotated video.

The most energy-efficient way to rotate video remains to physically flip the screen. Alternatively, you can use the video filters in VLC to manually rotate the video. But that will require extra CPU power since the hardware does not support it (or does not provide a way for applications to support it anyway).

Hmm, when I view the same video with Quicktime then it has the correct orientation.
So Quicktime seems to use another rendering API as VLC.
Do you agree?

Hardware is not the limiting factor because hardware would prevent rotation in Quicktime as well.

I am searching for a way to use one single multi-purpose video player for all my videos.
VLC is almost this software - except MOV auto-rotating.

Can VLC at least recognize that a MOV video needs rotation?
Or do I have to setup VLC rotate filter manually each time it is required ?
