Photon is a Java implementation of the Interoperable Master Format (IMF) standard. IMF is a SMPTE standard whose core constraints are defined in the specification st2067-2:2013
When Photon validates an IMF package with a video track that defines VideoLineMap metadata, it seems like Photon inverts the order. Here is the output using the latest build:
