Hello, I am trying to find out how can I copy timestamp related metadata from a file to another ?
My input file has UNIX timestamp (start time) which is what i need to copy. Here is what I am doing or have tried: 1) Read a video file frame by frame in OpenCV 2) Modify frames (image processing such as Gaussian blurring or sharpening) 3) Write back frames in a video using openCV. Written file has a start time of 0.00 ms. 4) Copy metadata from original file to modified file using below command : a) ffmpeg -i input.mkv -c copy -movflags +faststart output.mkv - This copies bunch of metadata but not the start time which is what I am after. b) fmpeg -i input.mkv -copyts -movflags +faststart output.mkv - This copies the video content as with all metadata including the start time. Any ideas how can I copy just the start time from originial file to modified file ?
