I'd like to be able to replace the audio with constant tones for certain intervals of a video. As an example, I might have a thirty second video, and want to insert 440 Hz from 5 seconds to 10 seconds and again from 15 to 20 seconds. Assume that I already have the 440 Hz tone in a .wav file that is five seconds long. Is there a way to specify a filter that toggles between the video's audio stream and the .wav file over the specified intervals (i.e. 5-10s and 15-20s)?
Thanks in advance! Cheers, Jon _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
