What is open? What this format has a function and specification? What is this?
https://en.wikipedia.org/wiki/High_Efficiency_Image_File_Format
Recently I received a reply that the GPAC MP4 not deploy images BPG because muxer can do screenshots HEIC.
If the question is how to create MPEG Image Files according to IFF, the current uses are:
To create a single image item:
MP4Box -add-image file.hvc:id=1 -set-primary 1 -ab heic -new iff_hevc_single_item.heic
To create N items from a tiled HEVC stream:
MP4Box -add-image counter_tiled_track1.hvc:tilemode=base:id=1 -set-primary 1 -ab heic -new iff_hevc_tile_multiple_items_tbas.heic
Currently, MP4Box uses the first sample of the HEVC stream to create the image item(s). This needs to be extend to be able to specify a sample time (instead of 0), to support the usual import_ parameters (e.g fmt, ...), etc. Tests and documentation are needed too ...
