I am completely new to the application development using shaka, I was trying to integrate a shaka player based ott app in an webkit based embedded device. While investigating an AV sync issue, I could see that the Player is loading multiple url in the video tag.

on investigating, I could see that the first stream is Audio only. while the second is the actual AV content.

Could someone help me here, on why shaka player is loading multiple URLs, How it is used in the video playback.

PS. It is observed in the default shaka player.
