[FFmpeg-user] Decklink input extra filter inserted

[Bartosz Ziemski]

Hi,

I am trying to save the Decklink input as a video file (applying specified
below filters) and I am wondering why the extra filter is inserted.
You can find the logs enclosed.
I would be really grateful if you could explain why the filter is auto
inserted there and if there is any option to avoid it.

Best regards,
