HLS

HLS is the worst technology for real-time streaming. It can only be useful on devices that do not support more modern technology, like WebRTC, MP4.

The go2rtc implementation differs from the standards and may not work with all players.

API examples:

HLS/TS stream: http://192.168.1.123:1984/api/stream.m3u8?src=camera1 (H264)
HLS/fMP4 stream: http://192.168.1.123:1984/api/stream.m3u8?src=camera1&mp4 (H264, H265, AAC)
