Adding support to provide 3D stereo information from the SEI via FPA (Frame Packing Arrangement) #7869

Open Ste-RH opened 4 years ago

Ste-RH commented 4 years ago

[REQUIRED] Use case description

It is great that there is support for reading 3D stereo information (stereoscopic-3d-video-box-st3d), but is it planned to support the SEI FPA (Frame Packing Arrangement) method of extracting this information as well?

Proposed solution

Adding support to extractors to pull FPA information from the SEI data would be simply wonderful :)

Thanks for suggesting this enhancement. As you are the first one to ask for it, we will probably not look into it in the near future. Feel free to make a pull request if you want the change to be added soon.
