Lossless Screencast with Audio on Linux
Hi,
i want to create a screencast from a video and tried this command line from here https://trac.ffmpeg.org/wiki/Capture/Desktop Code:
ffmpeg -video_size 1920x1080 -framerate 25 -f x11grab -i :0.0+100,200 -f pulse -ac 2 -i default output.mkv Code:
ffmpeg -video_size 1920x1080 -framerate 25 -f x11grab -i :0.0 -c:v libx264 -crf 0 -preset ultrafast output.mkv Code:
ffmpeg -video_size 1920x1080 -framerate 25 -f x11grab -i :0.0 -c:v libx264 -crf 0 -preset ultrafast -f pulse -ac 2 -i default output.mkv Code:
Unknown decoder 'libx264' EDIT What is the correct framerate in the command line? my computer is connected to the display with displayport running with 75hz. Do i need to capture with 75fps? |
