Then use VLC player to display the stream (the preview). My idea was to use ffmpeg to capture the video and audio signal and transmit this to a network stream (eg 127.0.0.1:6666). And simultaneously be able to start and stop recording, while the preview keeps playing.
Ultimately I will need to display this video on screen. This is the stream information for my current video/audio source, connected to the decklink card's hdmi port Stream #0:0: Video: rawvideo (UYVY / 0x59565955), uyvy422(tv), 1280x720, 59.94 tbr, 10000k tbn, 59.94 tbc pixel_format=uyvy422 min s=1280x720 fps=60.0002 max s=1280x720 fps=60.0002įfmpeg -list_options true -f dshow -i audio="Decklink Audio Capture" DirectShow audio device options "Decklink Audio Capture"įfmpeg -list_options true -f dshow -i video="Decklink Video Capture" DirectShow video device options ffmpeg -list_devices true -f dshow -i dummy DirectShow video devices I am trying to capture audio and video from a blackmagic decklink capture card using Windows 7 720p, but I cant seem to get the ffmpeg command line settings right.
