I have seen https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide and successfully used kvazaar and gpac to generate tiled videos.
However, I am looking for a method to stitch NxM independently encoded HEVC video stream into one mp4 file.
If I can control using the same video encoding parameters, is it possible to perform the stitching?
It should perform like `vstack` and `hstack` in ffmpeg.
Thank you so much.
