I am unable to reproduce this issue. What version of the CLI or SDK and of the livekit server are you using?

[jjchen01]

lk version 2.15.0

Also, I am using the Go SDK to validate it: github.com/livekit/server-sdk-go/v2 v2.16.0
It doesn't overwrite the S3 file but just appends to it.

Can you share your test case and SUT?

[biglittlebigben]

The latest version of the livekit server is v1.10.0. What version are you using?

[jjchen01]

Yes, I am using docker pull livekit/livekit-server:v1.10
What's the expected s3 file name from the following request with the flag livekit.ImageFileSuffix_IMAGE_SUFFIX_NONE_OVERWRITE?

It doesn't overwrite the existing data; it keeps appending:
xxx_00000.jpeg
xxx_00001.jpeg
...

req := &livekit.ParticipantEgressRequest{
			RoomName: event.Room.Name,
			Identity: event.Participant.Identity,
			ImageOutputs: []*livekit.ImageOutput{
				{
					CaptureInterval: 2,
					FilenamePrefix:  path,
					FilenameSuffix:  livekit.ImageFileSuffix_IMAGE_SUFFIX_NONE_OVERWRITE,
					ImageCodec:      livekit.ImageCodec_IC_JPEG,
					Output: &livekit.ImageOutput_S3{
						S3: &livekit.S3Upload{
							Endpoint:       env.ENV.S3_ENDPOINT,
							AccessKey:      env.ENV.S3_ACCESS_KEY,
							Secret:         env.ENV.S3_SECRET_KEY,
							Bucket:         env.ENV.S3_BUCKET_NAME,
							Tagging:        "lifecycle=ephemeral",
							ForcePathStyle: true,
						},
					},
				},
			},
		}

The expected filename in the example above is test1/test.jpeg.jpeg, and it is what I get when testing locally.

What is the output of lk egress list  --json for the affected egress?
