Thanks for providing the test streams, there's a PR (#1179) that adds support for fMP4 segments and fixes the issue.

[aler9]

Thanks again for providing the test streams, the HLS client has been improved in order to

• support fmp4 segments
• support audio in separate playlists
• support byterange
• start from the end of the stream if the stream is live
• improve synchronization
