Test stream

https://hlsjs-dev.video-dev.org/demo/?src=https%3A%2F%2Ftest-streams.mux.dev%2Fx36xhzz%2Furl_2%2F193039199_mp4_h264_aac_ld_7.m3u8&demoConfig=eyJlbmFibGVTdHJlYW1pbmciOnRydWUsImF1dG9SZWNvdmVyRXJyb3IiOnRydWUsInN0b3BPblN0YWxsIjpmYWxzZSwiZHVtcGZNUDQiOmZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ==

Configuration

  "enableWorker": true,
  "lowLatencyMode": true,
  "backBufferLength": 90,
  "progressive": true
}

Checklist

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

Steps to reproduce

Set "progressive": true.

Press 'play'.

First i seeked to 169, then quickly - to 471. And after that chunks irrelevant to 471 time began loading 16, 17 ... and many more. They are far from 471 time.

Expected behaviour

When seeked player should load relevant chunk near to seeked time.

What actually happened?

Player loads irrelevant chunks when seeked.

I can't reproduce the issue. Please provide a minimal reproduction page with the setup and seek commands that reproduce the issue.


You might also want to verify that your media element's currentTime is advancing when seeking as is expected. It is unclear why the target load position remains at 170 after seeking. That is not happening on my end.

link under 'Test stream' title above. Set "progressive": true. Play video. Then seek to one place and quickly - to another.

You can see from my logs that after last seek player is loading irrelevant chunks.

This does not happen every time.

Try several times.

Maybe set some network throttling (my network is not very good).

I definitely can reproduce it on you demo page. So it is reproducable.

I cannot reproduce the issue with the given steps even when throttling the network. I suggest disabling "progressive" mode. It has always been labeled "experimental" in the docs.


This issue could only occur when media.currentTime is not used to determine what to load following a seek:



  

    

      hls.js/src/controller/base-stream-controller.ts
    

    

        Lines 1756 to 1766
      in
      2d5daa6
    

  

  

    


        

          
           protected getLoadPosition(): number { 
        


        

          
             const { media } = this; 
        


        

          
             // if we have not yet loaded any fragment, start loading from start position 
        


        

          
             let pos = 0; 
        


        

          
             if (this.hls?.hasEnoughToStart && media) { 
        


        

          
               pos = media.currentTime; 
        


        

          
             } else if (this.nextLoadPosition >= 0) { 
        


        

          
               pos = this.nextLoadPosition; 
        


        

          
             } 
        


        

          
            
        


        

          
             return pos; 
        

    

  






It is unclear how this could happen. Once media is appended hls.hasEnoughToStart should be true. This is the only explanation for why "target" is 170 then 180 and so on:


[stream-controller]: Loading main sn: 17 of level 0 (frag:[170.000-180.000]) cc: 0 [0-63], target: 170


    
      
      
    
  


The next steps would be to either:


    

  1. Figure out how it was reset (this depends on your debugging the issue because I cannot repro it)
    2. 

  2. Or, see if setting nextLoadPosition in onMediaSeeking would resolve the issue
    3. 



For number 2, that would just require a change here:



  

    

      hls.js/src/controller/base-stream-controller.ts
    

    

        Lines 415 to 421
      in
      2d5daa6
    

  

  

    


        

          
           // in case seeking occurs although no media buffered, adjust startPosition and nextLoadPosition to seek target 
        


        

          
           if (!this.hls.hasEnoughToStart && !bufferInfo.len) { 
        


        

          
             this.log( 
        


        

          
               `setting startPosition to ${currentTime} because of seek before start`, 
        


        

          
             ); 
        


        

          
             this.nextLoadPosition = this.startPosition = currentTime; 
        


        

          
           } 
        

    

  






to something like:


    if (!this.hls.hasEnoughToStart) {
      this.nextLoadPosition = currentTime;
      if (!bufferInfo.len) {
        this.log(
          `setting startPosition to ${currentTime} because of seek before start`,
        );
        this.startPosition = currentTime;
      }
    }
