read audio length from videos

Hello Meir,

FV Player only checks the video/audio duration when it’s save into a FV Player instance. It does not support checking a video URL provided by other means, such as a custom field.

If you would like to avoid complexity of FV Player when inserting these audio files, perhaps the Video Custom Fields can help: https://foliovision.com/player/developers/video-custom-fields

Thanks,
Martin
