using ffmpeg to replace a single frame based on timestamp
3 avril 2022, par user1361529Is it possible to CLI ffmpeg to replace a specific frame at a specified interval with another image ? I know how to extract all frames from a video, and re-stitch as another video, but I am looking to avoid this process, if possible.



My goal :



- 

- Given a video file input.mp4
- Given a PNG file, image.png and given its known to occur at exactly a specific timestamp within input.mp4
- create out.mp4 with image.png replacing that position of input.mp4

Insert Frame to middle of Video
9 août 2015, par user1815241I have a case where I need to insert a frame (or many frames) to the middle of a video. I looked at doing ffmpeg cutting, inserting, and then concatenation but unfortunately I have a lot of cuts and the "stitch back" has a lot of choppiness. My thought was that I could leave the video "whole" and then insert frames as the exact spot(s) that I need to do that. This way I would solve the choppiness problem.
I am currently using ffmpeg and don’t really see any way to accomplish this task with that tool. Google doesn’t seem to be providing much help either.
Has anyone done this before ? What did you do to insert frames at specific spots.
As an FYI - I am doing my processing in Java, using FFMPEG, and my video files are mp4 (although I could convert).
Thank you in advance.

Build FFMPEG Library for Android
10 novembre 2019, par GunaseelanI have downloaded FFMPEG 4.2.1, but I don’t know how to use it on Android project, Some threads said, you have to build .so files, but don’t use Windows/CYGWIN, Some threads said directly extracts ffmpeg source into android project, and build with NDK, I can’t get any threads as much as clear,
It would be helpful if somebody redirects me on right path, I want to build my own, because existing libraries seems using old FFMPEG version, and also leads me huge app size.
