ploader.load() is never called after the initial load, causing the live playlist (with fMP4 segments) to stall.

What version of Hls.js are you using?

1.6.2

What browser (including version) are you using?

Chrome 137.0.7151.56 (Official Build) (64-bit)

What OS (including version) are you using?

Windows 10

Test stream

No response

Configuration

{            
autoStartLoad: false,
enableWorker: true,
ploader: custom,
xhrSetup: adding traceparent and token to request headers
}

ploader : is nothing fancy, only doing the playlist fetch so we can add query parameters about the player state.

Additional player setup steps

No response

Checklist

  • [x] The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues

Had to check those two, but I found no demo using live playlist with fmp4 and not using low-latency

  • [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

  1. Start a live stream using fmp4
  2. Playback stall after first live playlist is played

Expected behaviour

The PlaylistLoader should be created and load() invoked approximately every half of the target duration.

It was working just fine with 1.5.20.

What actually happened?

The stream-controller struggling to load the init (it is aborted a couple time before succeeding) The stream stalling since no playlist was fetch after the first one

The player is being configured to not load after the manifest is loaded with: autoStartLoad: false,. Remove this option, or call startLoad() after MANIFEST_LOADED.

robwalch avatar May 28 '25 19:05 robwalch

Can you share an example with your playlist loader that reproduces the issue? I can not reproduce the behavior shown in the logs (aborting init segment requests).

robwalch avatar May 28 '25 19:05 robwalch

Hello,

Thanks for the quick feedback.

I've removed autoStartLoad: false from the config and also the call to startLoad(). Now, ploader is still never called after the initial manifest is loaded, but I no longer see the "init load aborted" message.

Here’s the sequence of Hls.js calls we’re making:

  1. new Hls()
  2. attachMedia()
  3. loadSource

Below is the ploader.load() implementation:

public async load(
    context: LoaderContext,
    config: LoaderConfiguration,
    callbacks: LoaderCallbacks<PlaylistLoaderContext>
  ): Promise<void> {
    if (this.isAborted) {
      this.logger.error?.trace('Loader was aborted before load was called.');
      return;
    }

    this.stats.loading.start = Date.now();
    this.context = <PlaylistLoaderContext>context;

    let playlist;
    try {
      playlist = await this.playbackClient.getPlaylist(this.abortController.signal);
      this.stats.loading.end = Date.now();
    } catch (error) {
      this.stats.loading.end = Date.now();
      if (error instanceof DOMException && error.name == "AbortError") {
        this.onAbortError(callbacks, error);
        return;
      }

      this.onError(callbacks, error);
      return;
    }
    callbacks.onSuccess({ url: context.url, data: playlist }, this.stats, this.context, null);
  };

  private onAbortError(callbacks: LoaderCallbacks<PlaylistLoaderContext>, error: any) {
    if (callbacks.onAbort) {
      callbacks.onAbort(this.stats, this.context, undefined);
    }

    this.logger.debug?.trace(`Playlist request aborted.`);
  }

  private onError(callbacks: LoaderCallbacks<PlaylistLoaderContext>, error: any) {
    let message: string = 'Unknown error in HlsPlaylistLoader when loading next playlist.';
    let code: number = 0; 

    if (error instanceof PlaybackClientException) {
      message = error.message;

      if (error.code !== undefined) {
        code = error.code;
      }
    }

    callbacks.onError({ code: code, text: message }, this.context, error, this.stats);
  }

  public abort() {
    if (this.isAborted) {
      return;
    }

    this.isAborted = true;

    this.abortController.abort();
  };

  public destroy() {
    this.abort();
  };

And here’s an example of the playlist being returned:

Please share a page that reproduces the issue if you'd like help debugging.
