MPEG-DASH stream using VP9 codec

0

Hi
I want to create DASH streams using VP9.

But when I used MediaConvert to transcode an input mp4 (avc codec) to output DASH (VP9 codec), I'm not able to play the stream. I've successfully created DASH streams with AVC codec before and they play fine. Is there something I need to do differently for VP9?

Any help is appreciated.

Thanks!

Hi

Thank you for your questions. May I know the following?

  1. Which player did you use for testing the output stream?
  2. Could you send me your aws account ID, mediaconvert job ID and region in "private message"?

Hi

One more thing to remind, if you use s3 as streaming origin, please be reminded to enable the CORS in your S3 bucket: https://docs.aws.amazon.com/AmazonS3/latest/userguide/enabling-cors-examples.html

Thank you Michael. CORS is already enabled on the S3 bucket. As an experiment, I uploaded a VP9 encoded WebM (from public test source) and I'm able to stream it. But when I try to create a new VP9 Dash stream , I'm not able to stream it. I tried converting different inputs too, like mp4/AVC -> Dash/VP9, but in all these instances, I'm not able to stream the content. I think the media convert step must be the cause, but I'm not sure what change I need to make in the convert job.

Hi

We apologize for the inconvenience while using MediaConvert. We have identified the issue and are working to fix it. Unfortunately we cannot give a timeline on when this will be available. We will inform you as soon as we can. At this moment, please avoid to use $dt$ name modifier for VP9 codec. Instead, you can either choose to use $Number$ or $Time$ in name modifier.

Thank you Michael! Removing the $dt$ modifier resolved my issue.

Thanks again for the quick reply!
