[FFmpeg-user] Decklink output can't produce 1080i50

[Mustafa Al Ani]

Hi,

I'm trying to output an NDI stream (1080i50) using Decklink but the output
is always progressive, my decklink setting is set to 1080i50 and the NDI is
100% interlaced.

I'm not using any flags in the output side because I presume it should take
the input as is, but even when I use flags like " -flags +ilme" or setting
frame rate like "-r 25000/1000" or format code "-format_code Hi50" I'm
still getting progressive output.

Is this something I need to check in the Decklink SDK?

Your inputs are highly appreciated.

R,

Mustafa
