Detect whether media has sound #690
Description
Activity
The audioTracks property is only available with experimental flags enabled in most browsers, although it's been available for a long time. I'd consider this a relatively low priority enhancement, given that, and will bump it until there's better browser support.
See https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/audioTracks#browser_compatibility
If a media source doesn't have any sound, that should be detectable and communicated to the user.
You can use the media
.audioTracksproperty to check whether there are audio tracks. If there are none, the video can be assumed to be silent.You can use the Web Audio API to check for silence; but the processing is probably excessive. Might be better to add a flag for the user to declare that a video is silent.
if (videoElement.audioTracks && videoElement.audioTracks.length > 0) { return true; }
