Hello,

I would recommend opening a [support case](https://www.wowza.com/support/open-ticket) for further review.

Please have details about your source encoder(video,audio codecs, framerate, frame size, bitrate, keyframe interval) along with the below folders for review.

[install-dir]/conf

[install-dir]/logs (only latest logs after a restart and showing the VP9 transcoding is needed)

[install-dir]/transcoder

If you are not sure how to get this information please see the following tutorial.

[https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux](https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux)

If files are too big for email transport, please send a link to the files.

Regards,
