GetFile API and m3u8 (HLS) streaming
« on: February 19, 2020, 02:00:58 pm »

I've noticed that the resulting response to GetFile.m3u8 results in a response such as this in my case:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:6
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:EVENT
#EXTINF:6.000000,
/MCWS/v1/File/GetFile.ts?File=757250&Conversion=WebPanel&Quality=Very%20High&Start=0.0&Playback=2&HLS=1&Context=seg0.ts
#EXTINF:6.000000,
/MCWS/v1/File/GetFile.ts?File=757250&Conversion=WebPanel&Quality=Very%20High&Start=0.0&Playback=2&HLS=1&Context=seg1.ts
#EXTINF:6.000000,

...and so on.

Missing is the absolute URL to the request for the segments.  Why is it relative and can an absolute path be provided?

e.g. instead of "/MCWS/v1/file/GetFile.ts", can it be: "http://[my media server:port]/MCWS/v1/file.... ?

Its relative to the same server you got the m3u8 playlist from, which avoids a load of issues with proxys and whatnot. Any HLS client i've ever seen handles that just fine.

Thanks.  Could be the Emby mobile client then is at issue.

I'm adding the GetFile request into a stream (.strm) file.  Emby indexes this file on its server, and in its webclient has no issue playing back the stream from Media Center.  The Shield TV app also works; the iOS mobile apps from Emby however do not.

I can see 404 errors in the Emby server logs to the .ts files via the GetFile API because they are likely using relative URLs.  But only for the mobile clients.

I have an interesting use case for why I use Emby this way where Media Center is my primary server...  I'm going to run the request through a proxy in node.js and change the response from Media Center to add the domain to each URI for the .ts file and see if that makes any difference.
