[FFmpeg-devel] rotate video

[Koch Máté]

Hi,

 I've read a former post about rotating video, but the answer was not
 clear to me.
 I want to take an mjpeg stream from an IP cam and rotate/display it as
 realtime as
 possible.
 If there is no chance to do it with a command line switch, I have got
 an other idea:
 modifying and recompiling the ffplay to play everything rotated (for
 example simply
 change x and y coords before displaying the video, which mirrors the
 image, but its not a problem).
 Can anyone help me with this? Which is the source file I have to edit
 and how can I
 do it in the most simple way?

 Thank you,
 Best regards:
 Mate
