AWS Elemental Convert - Error video 360 degree when stream with media convert job of ouput HLS group

One thing I notice looking at your .m3u8 file is that your encoded video has an aspect ratio of 16:9. That aspect ratio isn't appropriate for 360 degree video. 360 degree video must be captured and encoded in an aspect ratio of 2:1 (which is equivalent to 360 degrees by 180 degrees.) This is also referred to as an "equirectangular" ratio. When your 360 video player attempts to play back a video that was not encoded at a 2:1 resolution it is forced to fill in the gaps with black.

Confirm that your source video is captured at a 2:1 resolution and that your encoding settings also target 2:1 resolutions.

Many thanks Kris,

After I changed encoding settings 1280x720 (16:9) to 1440x720 (2:1), it works perfectly.

My output video **not appear 2 black holes ** in movie. SOLVED

But when I stream video with quality greater than 2K, resolution is 2160x1080(2:1) or other quality 2K - 2560 x 1440 (16:9), 4K - 3840x2160 (16:9), 8K - 7680 × 4320(16:9)

The one thing I am having trouble with is embedding it into a web page to support both Safari and Chrome (I'm using video player (VideoJS) to play HLS video)

I do see an issue where the HLS index file doesn't load the movie automatically, but it just plays audio.

I have to refresh the page to see the whole video. Any ideas why?
