QuotaExceededError - BUFFER_FULL_ERROR in IE11 and Edge

[romsil]

In IE11 and Edge, it is not enough to just set this.config.maxMaxBufferLength to half of its value when we encounter a QuotaExceededError. We need to explicitly flush the buffer, or else QuotaExceededError keeps coming and buffering/playback will eventually stall.

This QuotaExceededError can be easily triggered by seeking back to 5-10s after a playback of 2-3 minutes in IE11/Edge.

Hi @romsiltp I spent some time trying to reproduce your issue with Edge/Win 10 but was not able to.
could you share a stream ?

Hello @mangui !
Sure thing! I reproduced the problem on your latest demo page both on Edge and IE11 so I will just give you the Repro Steps:

1. Open the following link on IE11 or Edge (hls.js v0.6.3 demo with the stream):
   http://dailymotion.github.io/hls.js/demo/?src=http%3A%2F%2Fedge.tpr-3ehznk.top.comcast.net%2Fdemo%2Fcontent%2FPDK_(VMS)%2F118%2F675%2FGodzilla_Final_Wars___Full_Movie___HD_1080p_(720p).m3u8&enableStreaming=true&autoRecoverError=true&enableWorker=true&levelCapping=-1&defaultAudioCodec=undefined
2. Let the video play up to 3 mins.
3. Seek to 0s-5s.
4. Let it play up to 3 mins again.
5. Again, seek to 0s-5s.
6. Playback will stall and QuotaExceededError will be repeatedly thrown in the logs. Watch out for “reduce max buffer length” in the logs as the value becomes negative. Playback never recovers from this point.
7. If playback doesn’t stall, repeat Steps 4 & 5.

I have attached the console logs in case you want them. Thanks.

Perfect. Will check tomorrow

ok I was able to reproduce it.
IMHO a better way to fix it would be to flush the whole buffer in QuotaExceededError only if current position is not buffered. let me check how to handle that.

Hi @romsiltp plz recheck on demo page / master branch. IE/issue should now be addressed.

I just checked it on the demo page / master branch both on IE and Edge. I could not reproduce the issue anymore. Thanks @mangui !
