Detecting on which frame there is audio presence on a video
26 août 2016, par drovI have a few video files that corresponds to a tv zapping (one channel with sound, then a black screen without sound, then sound again with the new channel)
I already detect pretty much everything but I would like to know how long it takes for the audio to appear after the end of the black screen.
Basically I extract the audio from the video and giving the starting frame I would like to know at which frame there is some audio again.
Then using that I can easily calculate the time it took for the audio to appear.

after @Mulvya comment I changed my for loop to
var volStr = '';
for (var i = 0; i < arrPairs.length; i++) {
volStr += "volume=enable='between(t," + arrPairs[i].start + "," + arrPairs[i].end + ")':volume=0";
if (i !== arrPairs.length - 1) {
volStr += ",";
}
}getting rid of the space between each grouping and it worked beautifully.
