I'm trying to remove logo from an .mp4 video format with ffmpeg on linux machine without re-encoding (for preserving the same quality) with the following command:
ffmpeg -i input.mp4 -vf delogo=x=270:y=190:w=40:h=40 -c:a copy output.mp4
and it give me the following errors:
Unrecognized option 'vf'
then a new error came up:
Unable to find a suitable output format for 'delogo=x=270:y=190:w=40:h=40'
ffmpeg always updating and it seems that they change command line arguments alot so any material or tutorial i find online seems to get out-dated quickly
I review their website documentation but can't get it to work, I think i'm missing something...?
so what is the correct command line in linux shell also, how to view or find out exactly the area coordinates to be removed before actually removing logo/overlaying it and keep testing every while
and how to overlay a solid color in certain area instead of removing logo transparently as well?
