+## s3hlssink
+
+Writes a single variant HLS stream directly to a specified S3 (region, bucket,
+path prefix) tuple. Takes the encoded audio and video stream as input, and uses
+`hlssink3` if available, else `hlssink2`. HLS stream parameters such as
+playlist length, segment duration, etc. can be tweaked by accesing the
+underlying sink using the `hlssink` property.
