HLS Range Error in flv-tag.js about videojs-contrib-hls HOT 14 CLOSED

@agask2agask2 Can you supply a URL to a manifest?

from videojs-contrib-hls.

here is the video im trying to stream https://s3.amazonaws.com/MichaelandLeann/Back2Basics/Chapter2/MasterChapter2.m3u8

from videojs-contrib-hls.

also while im in here does the adaptive bit rate work well in all browsers with flash? or do i need to get that MBR branch to do that?

from videojs-contrib-hls.

@agask2agask2 - the adaptive bitrate algorithm is handled in the javascript layer and works well in all browsers. The MBR branch was an exploration into additional features for multi bitrate content and is unstable at best. It should not be used at this time and will probably be removed of a more robust plugin in the future.

thanks for the quick replies guys, so i just have the one issue above then.

i just noticed this happens alot on full screen when i skip.. etc..
RangeError: argument 1 accesses an index that is out of range

this.view.setUint32(this.length, this.length);

using firebug console i can see it

from videojs-contrib-hls.

I am seeing the same error on some segments:

Uncaught RangeError: Offset is outside the bounds of the DataView videojs.hls.js:961
finalize videojs.hls.js:961
self.getNextTag videojs.hls.js:1980
(anonymous function) videojs.hls.js:577
request.onreadystatechange

the line in question is
this.view.setUint32(this.length, this.length);

from videojs-contrib-hls.

length is 16382 in the case where it fails for me.

this.bytes = new Uint8Array(16384);
this.view = new DataView(this.bytes.buffer);

this means that the length is a 4 byte int, which should go to pos 16382,16383,16384 and 16385. But the buffer only has 16384 spots making the last index 16383.

I dont understand the logic (yet) but it seems that either the buffer is to small, the length is to long, or the position is wrong.

After looking at some commits @dmlap has fixed similar problems by growing the array.
I monkeypatched a prepareWrite(this, 4); just before line 961 and it then worked fine.

I assume there is a better place to do that, maybe some of the buffer size calculations are off by 2?

@agask2agask2: looks like your video URL has been taken down since you opened this issue. We believe it should be fixed, please re-open if it turns out to still be a problem.
