3 years ago This is for doing a screen capture on a mac but it is a universal screen capture problem.
So I have this command:
ffmpeg -f avfoundation -i "2" -c:v h264 -crf 15 -vf "scale=1920:1280,fps=60,format=yuv420p" output.mp4
How would it get the avfoundation into the input stream?
I am trying to use this:
` input := ffmpeg_go.Input(""2"", ffmpeg_go.KwArgs{"f": "avfoundation", "c:v": "h264", "crf": "15", "vf": ""scale=1920:1280,fps=60,format=yuv420p""})
output := input.Output("output.mp4")
output.Run() `
your example is right, but you maybe mixed output args with input args? this works for me:
out := Input("default:none", KwArgs{"f": "avfoundation", "framerate": "30"}).
Output("output.mp4", KwArgs{"format": "mp4"}).
OverWriteOutput()
