Audio & Video mp.4

#1
Hello,

I'm trying to separated audio from video with mp.4 file, using ffmpeg command. Next keying only video, audio send to Axon card and doing overlaying channels . Finally on output Axon card I will trying gain overlaying audio with video.


Now it's working through this command

Code: Select all

PLAY 1-1 file.mp4 
MIXER 1-1 VOLUME 0

PLAY 2-1 file.mp4 FILTER fade=type=in:nb_frames=30 (video= black, play only audio)
It's possible using CasparCG separate audio from video on one Decklink Card?


I'm very appreciate to any suggestion.

Thanks
