Hi,
I want to add two libx264 libs into ffmpeg, where one libx264 is original one,
and another will be changed by myself.
How to add two libx264 libs into ffmpeg without changing two much code?
Thanks!

Then please write the content of the pipe in a regular file and provide it.

I agree, it feels like it should set the duplex mode by default when you
choose to output on

perhaps you need to set the duplex mode on 1 and 2, which then opens up sdi
3&4 to be individually programmed.
Yeah, I think that is how I use all 4
Hi Music Br,
What have you tried so far? when you say while running ffmpeg, do you want
to change the image overlay somewhere in the middle? or just in general?
Cheers,

I couldn't help myself and just tried remotely, it appears I might have
gotten some part to work.
In one terminal, i run:
ffmpeg -format_code Hp25 -f Decklink -duplex_mode half -i 'DeckLink Duo
(1)' -c:v libx264 -preset ultrafast -map 0 -segment_time 20s -f segment
I need to change an overlay image on the video and resize the video while
running ffmpeg. It is possible? If so, how to proceed?

I'll give that a go tomorrow, it sounds a bit strange, as it would mean

Hi Rik,
I think the duplex mode is only supported in ports 1&2.
Apart from that, I have never been able to enable video input on 3&4, I
spoke with Blackmagic support but never got a useful answer. Never trust
what they write in their products descriptions.
Please let me know if you got video
Hi Moritz,
Thanks for the swift response. Great observation, thanks! I had actually
already tried that before, but have just tried it again, it comes back with
a unsupported error.

Can you recommend 1 development board to good use with ffmpeg? Now I use

I will recompile ffmpeg,the input file is Linux named pipe file.so it is
not a regular file. the content is the device's audio stream(codec is g722).Let

Hi All,
I'm using a DeckLink Duo 2 card which supports 4 individual in or outputs,
but by default is set to Full duplex mode (input from sdi 1 is output on

I'm running Ubuntu Server 18.04 with the following ffmpeg build:
