Audio Issues in some of the downloaded mp4 files

[MohammedAbadi1991]

We have noticed that some of the downloaded mp4 files have audio issues.
Although attendees did not face any audio issues during the meeting when you download the generated mp4 file from the S3 bucket you will notice audio issues and you will not be able to hear the audio.

Hi,

The Chime SDK team launched a new service to provide meeting capture capabilities. You will not need to provision your own container infrastructure, you just need to call an API and provide an S3 bucket to receive the artifacts.

@MohammedAbadi1991 the only time I've seen that type of audio issue in the recording is when you run the recording demo on an under-powered instance type. What instance type are you running it on. It works well for me on a m5-xlarge.

Closing as we did not get any response

@albrich-me @achris Hey Guys , we are using EC2 instance of type t2.xlarge

[achris]

Can you try m5.xlarge as as @albrich-me suggested?

Have you made any customization to the parameters in record.js such as resolution, bitrate, etc?

@albrich-me The default instance type is t3.xlarge, should we update it to m5.xlarge? https://github.com/aws-samples/amazon-chime-sdk-recording-demo/blob/master/templates/RecordingDemoCloudformationTemplate.yaml#L49

[MohammedAbadi1991]

@achris @albrich-me We did not do any customization on the parameters under record.js.
I confirm that when we used the instance of type M5.xlarge, we did not face any issue.
Thank you!

@achris It would be interesting to look into porting the recording demo to the t4g.xlarge. If that can be made to work reliably it could solve the problem at a lower cost than even the t3.xlarge. The processor is ARM based but I think everything needed for the recording demo (Firefox, FFMEPG, Node) has an ARM version so it looks like it could work.
