Support for NITF MIL-STD-2500C W/CHANGE 2 (Motion Imagery, H.264)

[sei-rsteele]

Feature description

According to MIL-STD-2500C W/CHANGE 2 pages 36-37:

Image Compression (IC) values include motion imagery (CB, MB, C9, M9, CA, MA).

Is there any planned future support for motion imagery?

Additional context

No response

Is there any planned future support for motion imagery?

Not that I'm aware of. Unlikely to happen without funding / code contribution. Is it movies or individual frames that can be separated?

CC @bradh if he has some clues

There is support for a few of the TREs for the Motion Imagery Extensions for NITF. I added those because they seemed generally applicable, and the NITF Technical Board is moving those into STDI-0002.

However it's not clear how the motion imagery (time dominant) data would work in GDAL. There might be application specific subsets that could work, but a stream of frames is going to be a stretch.

I am willing to discuss further but for a new program you'd want to be using at least the Joint BIIF Profile instead of -2500C, and it might be worth getting in contact to discuss the NGIIS (ISOBMFF based) work.
