av_display_rotation_get will return NAN when the display matrix is invalid, which would end up printing NAN as an integer in the rotation field. This is poor for multiple reasons: * Users of ffprobe have no way of discerning "valid but ugly rotation from display matrix" from "invalid display matrix". * It can have unintended consequences on some platforms, such as Linux x86_64, where NAN is equal to INT64_MIN, which, for example, when printed as JSON, which uses floating point for all numbers, can end up as invalid JSON or wit a number that cannot be reserialized as an integer at all. Since NAN is av_display_rotation_get's error case, just print 0 (no rotation) when that happens. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> |
