I see that YouTube supports audio playback during slow motion playback. is it possible to play audio during slow motion playback using JW player? Currently there is no audio when slow motion video playback is enabled.
There is no built-in functionality to accomplish this, but could be possible with some extra code. Please see my example page at: http://qa.jwplayer.com/~abussey/demos/html5-playback-speed.html
Please note that this will only work if the player is rendering in HTML5. If the player renders in Flash, whether set that way in your settings or if it’s presented with a source that Flash is required for playback in a specific browser, this will not work.
Also, please note that the value of playbackRate determines whether or not the audio is muted during the slow motion or not. For example, I used to have the Slow Motion playbackRate set to 0.3, but the audio would be muted. Changing that value to 0.5 caused it to play the audio slowed down.
Obviously, this is not built-in functionality and we cannot provide support for it. Especially since updates to either specific browsers or our player, may brake this functionality. However, it should continue to work as long as the HTML5 standard for video elements stays the same and our player continues to pass HTML5-compatible media into <video> tags.
Please let me know if you need any more help or have any other questions.
