I’m having trouble figuring out the syntax for this. I want to generate a test file using video testsrc and audio sine wave. I can do both separately, but how can I get both together?
ffplay -f lavfi -i testsrc=s=1920x1080 (this works) ffplay -f lavfi -i sine=frequency=800 (this works) ffplay -f lavfi -i testsrc=s=1920x1080 -i sine=frequency=800 Argument 'sine=frequency=800' provided as input filename, but 'testsrc=s=1920x1080' was already specified. ffplay -f lavfi -i testsrc=s=1920x1080,sine=frequency=800 [lavfi @ 0x7faf0e821400] Too many inputs specified for the "sine" filter. testsrc=s=1920x1080,sine=frequency=800: Invalid argument _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
