Hls.js: 4k video gets stuck

[ilgooz]

can you please check this? it frequently gets stuck on the blue point of progress bar and consumes my whole cpu, tries to buffer in some kinda infinite loop. see the red highlighted numbers(beginning of lines) from logs.

I noticed that this only happens while chrome developer tools is open and _disable cache_ is enabled. is there any reason to this, maybe relevant with media provider?

[mangui]

from your logs it looks like that the video playback is stuck just before the second video buffered timerange, although hls.js is trying to seek over the hole ...

media buffered : [0,3.970611][4.004172,56]
adjust currentTime from 4.004171 to next buffered @ 4.004172
adjust currentTime from 4.004171 to next buffered @ 4.004172
...

I cannot reproduce on Chrome 49.0.2623.87 OS.X
which version are you using ?

an option might be to nudge a little bit video.currentTime when this happens
you can try to replace
https://github.com/dailymotion/hls.js/blob/master/src/controller/stream-controller.js#L1029
by
media.currentTime = nextBufferStart + 0.001;

for example

i see. sorry to not providing my env in the first place. here it is:

• Chrome: Version 48.0.2564.109 (64-bit)
• Ubuntu 15.04

A side node: we built a custom loader via Loader API. As I've seen, _Loader.abort()_ method continuously getting triggered by hls.js and playlist changed to level 0 again and again. but it continues to playing & buffering video if I click a random place on progress bar.
currently we've changed the video url with something else but I can investigate this and help to you to reproduce it at the first chance.

[mangui]

For the side note, could u open another ticket and provide debug logs ?

[ilgooz]

same thing is also happening with firefox(44.0) on same machine. I guess this not specific to chrome. and disabling cache is not relevant with this.

following log message repeats tens of times in a row just like what was happening on chrome. as you mentioned.
