Extracting each tile separately

Open mrigankchugh opened this issue 3 years ago • 2 comments

Say I specify the 4 X 4 tiles when I am encoding to hevc. Can I specify the tile number and get the video enclosed in that tile for a time period?

Hi,

Never tried to do this so myself.

There is the MCTS Extractor in the HEVC reference software (https://vcgit.hhi.fraunhofer.de/jct-vc/HM/-/raw/master/doc/software-manual.pdf?inline=false) but Kvazaar does not implement the required SEI messages for this to work.

Then there is mp4box that can split the tiles into separate tracks (https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide) but I'm not sure if you can extract the individual tiles in a format that is suitable for your use case.

Hey @mrigankchugh, did you find a way to do this? If yes, please share
