I am interested. I didn't answer yet because I talked to Felix about it

My understanding is that your case would require the application to set
up two separate filters on different file descriptors, i.e. one with
DMX_PES_OTHER+DMX_OUT_TAP. Otherwise you can't stop your recording
without stopping VBI.

But I know that what you describe is how the av7110 driver behaves. In
my opinion it is a bug.

I think _IO('o', 5x) should be replaced with _IOW('o', 5x, __u16).

Best regards,
