HLS Adaptive Bitrate Files Not Generated

[PranayPant]

Summary

The manifest file under /opt/data/hls/<STREAM_NAME>/index.m3u8 does not include any information about resolutions or dimensions, preventing the browser hls player from requesting the appropriate encoded video as per resolution and network latency.

Reproduction

1. Clone repo
2. Run docker compose up
3. Open OBS --> Settings --> Use rtmp://localhost:1935/hls for Custom Server with stream key hello as shown below.
   
4. Request http://localhost:8080/live/hello/index.m3u8 from any HLS player from the browser.
5. Throttle network speed in DevTools as shown below (Chrome browser)
   
6. Observe payload size of each .ts segment is the same, causing buffering
7. Inspect files in docker container under /opt/data/hls/hello. No adaptive resolution files found.
