FFplay allows you to stream created video and FFmpeg allows you to save video.
+The following command creates and saves a 10-second video of SMPTE bars:
+ffmpeg -f lavfi -i smptebars=size=640x480 -t 5 output_file
+ This command plays and streams SMPTE bars but does not save them on the computer:
+ffplay -f lavfi smptebars=size=640x480
+ The main difference is small but significant: the -i
flag is required for FFmpeg but not required for FFplay. Additionally, the FFmpeg script needs to have -t 5
and output.mkv
added to specify the length of time to record and the place to save the video.
