Code

 val defaultHttpDataSourceFactory =
            DefaultHttpDataSourceFactory("Mozilla/5.0 (Linux; U; Android 4.0.3; ko-kr; LG-L160L Build/IML74K) AppleWebkit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30").apply {
                defaultRequestProperties.set("access_key", "")
                defaultRequestProperties.set(
                    "secret_key",   "" )
                defaultRequestProperties.set("bucket_name", "")
                defaultRequestProperties.set("region", "")

            }

        return ProgressiveMediaSource.Factory(defaultHttpDataSourceFactory)
            .createMediaSource(uri)

when check network profiler i found request has headers correctly.

Answer 1

Solution was to generatePresignedUrl :

add next to build.gradle:

implementation 'com.amazonaws:aws-android-sdk-s3:2.9.2'

object AmazonS3Helper {

    fun getURI(objectName: String, s3: S3Credentials?): Uri? {
  
        val myCredentials: AWSCredentials =
            BasicAWSCredentials(s3?.accessKey, s3?.secretKey)
        val s3client: AmazonS3 = AmazonS3Client(myCredentials)
        val region = s3?.region ?: "eu-west-2"
        s3client.setRegion(com.amazonaws.regions.Region.getRegion(region))
        val request = GeneratePresignedUrlRequest(s3?.buckeName, objectName)
        val objectURL: URL = s3client.generatePresignedUrl(request)
        return Uri.parse(objectURL.toString())
    }
}

then use uri as normal with exo-player

NOTE: S3Credentials it is just wrapper class to have S3 header values like(bucket_name, etc).
