How to encode MV-HEVC spatial videos using HLS tool correctly?

Hi all, I am a graduate student who is looking into making MV-HEVC videos streamable. May I ask that is it possible to encode mv-hevc videos with the HLS (Http Live Streaming) protocol? I've been trying to use the HLS tool by Apple to encode a spatial video recored by VP.

mediafilesegmenter -iso-fragmented -t 4 -f sp_video-1-vp spatial-video-by-vp.MOV

But the output HLS playlist file doesn't look like the format that Apple proposes in the WWDC video. For example, the attribute EXT-X-VERSION is 7 instead of 12, and no attr REQ-VIDEO-LAYOUT=CH-STEREO which should be the key indicator of the spatial video type.

From what the WWDC video showcased, I assume Apple's HLS tool supports it. Maybe my usage is not correct. Just curious what you guys think about it, thank you!

Yes, the tools should work with MV-HEVC content. Are you running a correct version? It should be version 1.22 to get that behavior.

  • Yes, I am using v1.22.4. Could you please show me an example command via mediafilesegmenter that can convert a spatial video recored by iphone 15 pro to valid HLS chunks? Thanks!
