OMXPlayer video rotation

[P4d0uch]

Hello,
Is there any way to rotate video in OMXplayer? Im using the official 7inch screen in portrait mode (see the picture) , but I wanted to play in landscape mode. Adding the

Code: Select all

--orientation 90

does rotate the video, but not in a way i have imagined (second picture)

Thank you for your help.

That's going to be the fault of the omxplayerGUI that you're wrapping omxplayer with.
It will have specified an x and y offset, and width and height that the image is to be rendered in to, and it's not modified that area based on the rotation. The GPU therefore does what it is told and renders the image into the defined area, but it has to stretch it to do so.
Without tracking down the source to the GUI you won't be able to resolve the issue, but it is just a couple of parameters to the display region that is wrong. omxplayer from the command line may do the correct thing for you by default.

Yes, omxplayerGUI takes it coordinates from desktop and that won't change. But is also supports a mode without a GUI and if you use that (create a matching preset) you could run the rotated video (full screen only). Start with the nogui preset and add "--orientation n" option.

Thank you so much. It works great. Just added

Code: Select all

--orientation 90
--aspect-mode stretch

. And lower resolution video:


Is there any way to get at least play/pause and/or stop button? If not I will have to add another button to the back of the case and get at least some playback control using GPIO pins, because I´m trying to get the Pi working without keyboard and mouse.

In full screen mode only keyboard controls are available.
