How it was verified

Built by the testsrc generator (gen v0.2) and verified with FFmpeg 7.1.5-0+deb13u1 and GStreamer 1.26.2 in snapshot 2026-11-02, before it was published: the file has the property this page describes, and decoding it gives the expected result.

With a token: the file, how exactly it was built, the full fact sheet, and the expected result the checker judges a player against.
