about readme vod_hls_container_format mpegts and fmp4 #1403

Closed wzzc-dev closed 11 months ago

wzzc-dev commented 1 year ago

I try to use VOD module to play H265 format mov file, can play directly without using encryption case, encryption case need to set VOD: mpegts, but why Apple does not support HEVC over MPEG TS in the document

vod_hls_container_format syntax: vod_hls_container_format mpegts/fmp4/auto default: auto context: http, server, location Sets the container format of the HLS segments. The default behavior is to use fmp4 for HEVC, and mpegts otherwise (Apple does not support HEVC over MPEG TS).

You're asking me why Apple decided not to support HEVC with MPEG-TS?! last time I checked, I wasn't working for Apple...

Anyway, it's explicitly started here: https://developer.apple.com/documentation/http_live_streaming/http_live_streaming_hls_authoring_specification_for_apple_devices "1.5. The container format for HEVC video MUST be fMP4."

In my understanding, Apple wants to deprecate MPEG-TS in general. They can't remove it entirely due to all the streams out there that use MPEG-TS. When they added HEVC, they already supported fMP4, and since it was a new feature, they didn't have to worry about backward compatibility. So they preferred not to continue digging the MPEG-TS hole any deeper, and require that HEVC will use only fMP4.

On which player/device are you testing? Can you send the stream URL?

On which player/device are you testing? Can you send the stream URL?

I tested it on vlc Player for windows and ios

wzzc-dev commented 1 year ago

Can you send the stream URL?

When vod_hls_container_format:fmp4, the slice file can be retrieved but cannot be played

erankor commented 1 year ago

I meant a URL that I can use to pull the stream and check...

han4235 commented 1 year ago

OK

https://u7p3m3xe.dev-space.eulix.xyz/space/media/hls/hvc1.mp4/index.m3u8 @erankor sorry this is the url that can't be played

erankor commented 1 year ago

There are a couple of unrelated issues with this URL -

  1. It's an HTTPS URL that returns HTTP URLs - update the conf to either use relative URLs or to return https://
  2. The internal hostname used for the segments (eulixnetwork-server.bp-cicada-dev.svc.cluster.local) does not resolve

I assembled two m3u8 index files

I need iv, so I'm going to comment this out, but I don't think it has anything to do with that

As previously requested - I want a valid URL that shows the problem, not a paste of an m3u8... The previously sent URL still returns HTTP segments and a hostname that does not resolve.

http://123.60.17.171:3080/space/media/hls/hvc1.mp4/index.m3u8 plays fine on my iPhone. Maybe you are testing on some device that does not support HEVC.

On which player/device are you testing? I can't play it with iphone11/vlc

erankor commented 1 year ago

I tested on iPhone XR running iOS 15 / 16 (I've just upgraded to 16 and it worked before and after the upgrade)
