Currently, it seems hls.js does not have any form of "suppression" or "marking" of problematic levels. For example, if there are a number segments in a level that are 404ing, hls.js would step down to a lower level but then immediately retry the higher level which leads to unnecessary network requests. It initially seemed to me this line

hls.js/src/controller/level-controller.js

Line 303 in fcf8440

this.timer = setTimeout(() => this.loadLevel(), delay);
introduced in #1452, would solve the issue but it looks like it's simply delaying any level request, not the problematic one.

Is there currently a way to achieve this?

Environment
Steps to reproduce
  1. Start playing the stream.
  2. 404 fragments on the highest level. ( I did this via Charles )
  3. Observe hls.js switch down to the lower level and frequently attempt to switch back to level since bandwidth is available.
Expected behavior

The player should avoid switching to the problematic level for a set amount of time. That time could be config driven.

Actual behavior

The player continues to try to switch to the level even though segments are being 404'd.

A few thoughts:

  1. Should we just leave this up to client code? I foresee difficulties in signaling suppressed levels so that corresponding controlbars can update. For example, in the JW fork we've implemented a simple suppression system with a custom levelEmptyError code and a removeLevel api:
if (details === 'levelEmptyError') {
                this.hlsjs.removeLevel(data.level);

Removing the level probably isn't ideal for everyone. However, an API/event-driven approach would allow clients to choose how to handle an unavailable level. One downside is that it requires users to write more code.

  1. Can we do better than a fixed time delay? For live it might make more sense to set it to the average level length, and maybe increment it for each failure. For VOD it probably makes sense to never try again.

Thanks for the feedback!

  1. As levels are marked it is added to an object like so: https://github.com/video-dev/hls.js/pull/1536/files#diff-dfdf661f3b90cc148d83ce6228105a50R31 Perhaps that object can be exposed so it can be referenced by clients.

  2. That's an interesting proposal, I'd have to think more about it. What would be the incrementing value be? For example, if the average level length for level 4 is 50 and there was 1 error on the level would the delay be 50? Then if there's yet another error on level 4 what would the value be?

Hey, just a quick question at first, what about the HLS built-in fallback functionnality?

We are supporting that. You can have redundant playlists, and when on fails the client blacklists it and fails over to the alternative.

See "Redundant Streams":

hey @tchakabam,

The scenario I'm describing is for situations where there aren't any redundant streams in the playlists.
