When adding/updating HLS stream URLs, pick the network endpoint that is most likely to work reliably:
master.m3u8, playlist.m3u8, manifest.m3u8, index.m3u8) instead of redirect chains or single-bitrate links.http-user-agent and/or http-referrer).Example (headers + adaptive):
#EXTINF:-1 tvg-id="Example",Example Channel (720p)
#EXTVLCOPT:http-user-agent=Mozilla/5.0 (X11; Linux x86_64; rv:149.0) Gecko/20100101 Firefox/149.0
#EXTVLCOPT:http-referrer=https://www.example.com/
https://edge.example.net/livecast/ik:example/manifest.m3u8
This reduces playback failures caused by redirects, missing headers, or non-load-balanced direct hosts.
