How to cancel failed load?

[bknill]

This relates to #4070

I have loads of videos converted to streams with WebMs and MP4s (CMAF).

We have a few cases where some videos are failing as WebM streams in the MediaPlayer as highlighted above. I'm still trying to work out what's causing this but in the meantime I want to fallback to MP4s if it fails.

I can catch the error, I want to re-initialise the player with the new URL when this happens, however I just get a crash and the player stops - after the new URL has been applied.

You can see the line Error caught - reinitialising with new URL which is where I'm trying to apply the new video.

These are the settings I'm using

      debug: {
        logLevel: dashjs.Debug.LOG_LEVEL_DEBUG,
      },
      streaming: {
        abr: {
          //initialBitrate: { audio: -1, video: 4000000 },
          useDefaultABRRules: true,
          additionalAbrRules: {
            insufficientBufferRule: true,
            switchHistoryRule: false,
            droppedFramesRule: false,
            abandonRequestsRule: false,
          },
        },
      },

And I'm calling DashPlayer.initialize(videoEl, url, false) when it happens.

How to I stop this error crashing the player and re-initialising with the new URL?

OK applying the change on 'streamTeardownComplete' seems to work.

It's pretty slow tho, is this the best way?
