Hi,I have some questions regarding the article "HLS Authoring Specification for Apple Devices".Spec: You SHOULD use video formats in which the parameter sets are stored in the sample descriptions, rather than the samples. (i.e., Use 'avc1', 'hvc1', or 'dvh1' rather than 'avc3', 'hev1', or 'dvhe'.)Questions: Although "hev1" codec type support appears, we are having trouble playing on the client. Is "hev1" codec type supported? Or "hvc1" must?

Hi All, I am receiving this error "Segment exceeds specified bandwidth for variant" from media validator and also AVPlayerItemNewErrorLogEntry. What problem can this error cause. For example, can it cause video stopping for 2-4 sec and sound continues. Or can it cause any problem aside that? Thank you

Hi All, CoreMedia (HTTP Live Streaming) Profile and Logs tool does not start. Is there another way to trigger it? Thank you.

On an iPhone you will feel a short vibration when a sysdiagnose is successfully triggered."

Hi, AppleTV or native device uses 30 or 60 fps (Hz) display timing. In our application our HLS streams are always 25 or 50 fps. Do we have to set any AVPlayer parameter in application to not to have any user experience problem for displaying 25/50fps content on 50/60 display layer? Thanks.
