Make MP4 video using JPEG 2000 frames and ROI
21 mars 2012, par LeandroI'm having a hard time trying to figure out how to solve the following problem.
I have a set of jp2 frames. I want to save them as a .mp4 video for archiving (which is great because it supports motion compensation) and then be able to extract the frames as jp2 files again.
I have this working with a set of tools/libraries like ffmpeg. The issue is that I also want to include a ROI in the original jp2 images.
When I do that, the video shows nothing where the ROI originally was, and when I use ffmpeg to go back to the original files, the frames are still broken.
I tried going from JPEG2000 w\ ROI to another format before making the mp4 file, but every tool I use seems to have the same results : the ROI gets translated as a square w/o nothing there.
Any help would be greatly appreciated.
Thanks !
