sorry for the newbie questions.... I need to perform 90 degree rotation of each AVFrame. I need to do it programmatically rather then using filters on ffmpeg command line. I was trying to understand how to do it, but unfortunately there is not much details on AVFrame.data and linesize elements. I am using YUV_420 format and I understand there will be only 3 references in data and linesize. That is as far as I got. Any information would be greatly appreciated.
