#8663 closed defect (needs_more_info)

Different encoding results depending on output format (-f)

Description

Using '-f mp4' results on deterministic execution, as I expected.
Using '-f tee' also results on deterministic execution, as I expected.

Comparing '-f mp4' and '-f tee' executions doesn't give same results.

I can observe the differences by running the attached script.

Tested with libx264 video codec.

Likely intentional difference between Annex B and MP4 H.264 framing.
