encoder linux decklink vlc

PostWed Nov 28, 2012 3:51 pm

Hi,

I'm currently trying to make a stream on linux system using decklink card and vlc, facing some problems getting audio, so any tips for setting up first part of command is appreciated. Also if you have good tips for 1920x1080 x264 profile tips also welcome.

Code: Select all
decklink:// --decklink-aspect-ratio=16:9 --decklink-mode=Hi50 --decklink-audio-rate=0 --rt-priority --swscale-mode=0 --live-caching=500 --sout-deinterlace-mode=linear --sout-mux-caching=500 --sout '#transcode{venc=x264{profile=high,ref=5,sub=5,me=hex,subme=9,merange=16,cabac=1,bframe=16,vbv-maxrate=1200},vcodec=h264,vb=2500,scale=1,acodec=none,threads=6,high-priority}:rtp{sdp=rtsp://0.0.0.0:8000/test.sdp,caching=100}' --no-sout-transcode-hurry-up

Hello there good people!

I have Decklink Studio card.

Is there any chance that some of you could write step-by-step guide on how to make an audio and video stream using VLC and Decklink card on Linux operating system?

I have been trying to do this for quite long time without any success.


Thanks in advance.
