It gets really complicated when you get into overlapping file types, like with ISOBMFF. An .mp4 can also, simultaneously, be a valid .3gp because those are profiles of ISOBMFF. On the other extreme, JPEG is secretly two different incompatible formats (JFIF and Exif), and a video file with a different codec in the same container, or even a different track layout, might as well be a different format. |
