Zooming [cropping] certain area of video #206

Hi there,

Will it be possible to make omxplayer zoom on a specified area of video?

Example, CCTV feed coming in, would like to digitally zoom (blow-up) an certain area of video.

Thanks John

You can do this before starting omxplayer (command line option --win). It's unlinkely to be added as a dynamic runtime option as it requires quite a lot of keys and some sort of UI interface to control it, and seems beyond the scope of omxplayer. Maybe an interfact to change the displayed rectangle could be exposed over the dbus interface, and a separate app could control this.

As far as I understand, the --win option only controls where the video should be rendered and the not which piece. Am I understanding it correctly?

I believe somthing like --win "-128 -128 1408 738" would zoom in (on 1270x720 screen).
