Why mid-roll ad not working when changing playback speed from 1 to 2?

[ruby-duongtv]

Can you explain to me why videojs is not playing ads when set video playback from 1 to 2?
Thank for your help.

Hello @T-Duong ,

Would you be able to share a code snippet or sample project where this change is being done? I think that would help be in debugging any issue you are experiencing.

Thank you,

@Kiro705
Sorry, I can't share all the sources of my project. Can you help me?

[Kiro705]

Hello @T-Duong ,

Thank you for sharing the code snippet, I was able to see the issue by adding the following line to the plugin's sample app:

 playbackRates: [1, 2],

I was able to see that ads are not played at x2 speed. Testing on a HTML5 basic

I can plan to look into a fix, but right a work-around would be to use a different player.

Thank you,

@Kiro705
Thank for your support!

[dioramayuanito]

are there any workarounds to solve this case?

[Decoydoll]

Hello @Kiro705 ,

Is there any update about this? Thank you!

[dioramayuanito]

My temporary solution is : https://www.youtube.com/watch?v=w67wSxbyQTw

I get all cue-points from

var cuePoints = player.ima.getAdsManager().getCuePoints();

and if currentTime in timeupdate event 2 secs near/before of each cues, then i change speed to 1x
