#1615(avfilter:new): video diff filter
#1615: video diff filter -------------------------------------+------------------------------------- Reporter: ylluminate | Type: Status: new | enhancement Component: avfilter | Priority: wish Keywords: diff, | Version: difference | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- It would be useful to have a visual diff tool for videos that will create a resultant differential video of two videos. This could be used in a number of scenarios from simply seeing more easily the differences of one encode to the next to many other applications. With some overlay+pad magic you should be able to compare img1,img2 and diff on the same image. Similarly should function with vid frames. It would be useful to have a few different styles of diffing from an outline to color inversion and clipping similar to what is demonstrated here: http://jeffkreeftmeijer.com/2011/comparing-images-and-creating- image-diffs/ -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1615> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

Since there is no activity related since a while, someone may want to pick it and make something out of it. It shouldn't require that much work. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1615#comment:2> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
