I have a stream.m3u8 file with the following contents: #EXTM3U #EXT-X-VERSION:11 #EXT-X-DEFINE:QUERYPARAM="token" #EXT-X-STREAM-INF:BANDWIDTH=400000,RESOLUTION=640x360 360.m3u8{$token} #EXT-X-DEFINE:QUERYPARAM="token" #EXT-X-STREAM-INF:BANDWIDTH=1000000,RESOLUTION=960x540 540.m3u8{$token} #EXT-X-STREAM-INF:BANDWIDTH=2000000,RESOLUTION=1280x720 #EXT-X-DEFINE:QUERYPARAM="token" 720.m3u8{$token} #EXT-X-STREAM-INF:BANDWIDTH=8000000,RESOLUTION=1920x1080 #EXT-X-DEFINE:QUERYPARAM="token" 1080.m3u8{$token} #EXT-X-STREAM-INF:BANDWIDTH=16000000,RESOLUTION=3840x2160 #EXT-X-DEFINE:QUERYPARAM="token" 2160.m3u8{$token} The requesting URL is https://example.com/stream.m3u8!?token= and I am using an iPhone 15 running iOS 17.1. The QUERYPARAM substitution as described here is not working, because the requested URL for 540.m3u8 does not have a token appended it; I know this because I checked my apache error log. The file is hosted on a Debian 11 server. Have I implemented this correctly, and do I have the correct tech stack? Furthermore, what debugging tools should I be running to investigate further?
