  • [x] The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues
  • [x] The issue occurs in the stable client (latest release) on https://hlsjs.video-dev.org/demo and not just on my page
  • [x] The issue occurs in the latest client (main branch) on https://hlsjs-dev.video-dev.org/demo and not just on my page
  • [x] The stream has correct Access-Control-Allow-Origin headers (CORS)
  • [x] There are no network errors such as 404s in the browser console when trying to play the stream

Steps to reproduce

just play test stream

Expected behaviour

Play normally until the end

What actually happened?

When the first TS file of an HLS video lacks audio data, hls.js throws a bufferAppendError. This situation commonly occurs when the user's streaming SDK or other streaming tools initially push video without audio。

Providing an HLS Multivariant Playlist with a STREAM-INF tag and CODEC attribute would result in the proper SourceBuffer setup. The current version does not reset MediaSource and SourceBuffers upon discovering new media tracks (audio or video) in segments not present in previous segments.

@robwalch

add EXT-X-STREAM-INF tag and CODEC attr， but still got bufferAppendError

#EXTM3U #EXT-X-VERSION:3 #EXT-X-STREAM-INF:BANDWIDTH=140800,RESOLUTION=640x360,CODECS="avc1.64001e,mp4a.40.2" stream_0.m3u8
