Environment

[x] The MPD passes the DASH-IF Conformance Tool on http://dashif.org/conformance.html
[x] The stream has correct Access-Control-Allow-Origin headers (CORS)
[x] There are no network errors such as 404s in the browser console when trying to play the stream
[x] The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
[x] The issue occurs in the latest reference client on http://reference.dashif.org/dash.js/ and not just on my page
Link to playable MPD file: http://mediapm.edgesuite.net/dash/public/nightly/samples/dash-if-reference-player/index.html
Will happed with any MPD file.
Dash.js version: happen in dashjs 2.5.0 and 2.6.0
Browser name/version: chrome + FF

Steps to reproduce

I'm using videojs with dashjs. and the issue appears in both versions.
This is the npm wrapper that I'm using:
https://www.npmjs.com/package/videojs-contrib-dash
I have a videojs player, with an ability to jump backwards, so I'm using videojs API currentTime with the calculated time.
1. When triggering currentTime backwards sometimes the buffer start loading after the requested time and load all the way to the end of the buffer without loading the requested time (And since the index isn't retrieved infinite spinner appear ).

Observed behaviour

The buffer never loads the requested time index

You can see in the log how the time to seek is 290.727 but the buffer is loading from 300.8
From that point on, it will just start loading chunks.
On dash 2.6.0 the same issue apears with reference to ScheduleController

Hi @arkadash,

Probably I am missing something but I am not able to reproduce this issue. If I didn't understand bad, you are just doing a seek back operation in one of the sample vod streams, isn't it? how frequently you reproduce this issue?

Out of videojs and video-contrib-dash, can you reproduce this issue in latest version of the reference player (http://reference.dashif.org/dash.js/v2.6.0/samples/dash-if-reference-player/index.html)?

epiclabsDASH on 25 Sep 2017

It happens sometimes.
I created a simple dedicated HTML with the problem reproduced (attached):
Dash.js version 2.6.0
videojs-contrib-dash 2.9.1
(both latest versions)

Reproduce instructions:

go to the some point in the middle of the media
click on the "step back 10 sec" button
wait and see if the spinner disappear - sometimes it will stay and you can see the loading chunks problem.

Got it, I could reproduce the issue in dash.js reference player after the latest instructions (by the way, your zip file can't be accessed. I get an unauthorized response).

I am wonder if this could be related with #2189. Seems a completely different issue, but could be related somehow (issue with management of buffers?).

epiclabsDASH on 27 Sep 2017

Uploaded the Html file and console log again as txt:

demo.txt
demo logs.txt

The issue seems to be close to the safari one. The browser is fetching from n+1 which is what I can see in my logs. But I can't be sure if that is the exact same bug origin.

Thank you

arkadash on 28 Sep 2017

@arkadash, has your log been recorded with this stream https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd ?

nicosang on 29 Sep 2017

Yes, I'm using that manifest url.
The demo.txt (you can change it to .html) is a demo that I created in order to simplify my actual code and remove noise from other components. The url can be changed to any manifest, just change the var manifestUrl.
I reproduced it with many manifests files with remote and local file loading (to eliminate network problems).

I think there is two different problems. First one is due to automatic prunning process of buffers done by browser. In your first log, we can see that the video segment at time 308 is already loaded for dash.js. Video buffer range starts at time 310, so actually video segment is not already loaded.
The second issue is due to misaligned video and audio segments. There is no audio data at time 368.865. Audio IndexHandler should return index 91 instead of 92 to be sure to have data at time 368.865.

nicosang on 1 Oct 2017

I'm not sure about the second case. I was able to reproduce this issue with many videos that has audio data at the described time.
Is it somehow possible to fix this issue with configuration without making performance issues? How do I continue from this point?
Thank you,
Moshe.

arkadash on 8 Oct 2017

Hi @arkadash ,

both use cases can occur with all video streams according to me. I don't think that you can fix the issue with configuration. We have to fix it in the dash.js code. It sould be top priority issue to fix in the next release.

Getting the exact same issue here.

Seeking to an unloaded segment (particularly where there is buffer before/after) leads to an eternal pinwheel.. even when seeking to a spot that previously worked in some cases. It seems it will "recover" itself once... if you seek to an already-loaded segment then seek back, but after that the next time it jams it's jammed for good.

This can happen even when seeking to 0 leading me to believe it is not related to the mpd file or segmentation of the video.

All segments are there, and the video plays perfectly when left to play organically on it's own, also seeking forwards works (even when seeking to the exact same unbuffered section as when trying to "seek backwards").

No network requests are made while this error is happening, leading me to believe the buffer was emptied (by the browser or the player) and the player isn't aware it needs to be reloaeded, and thus doesn't reload from the network (where it infact exists).

here is the error after scrubbing backwards:


Debug.js:127 [37402] Getting the request for video time : 2188 
Debug.js:127 [37402] Index for video time 2188 is 546

and after some seeking/playing/pausing this happens in perpetuity:

Just an update, it doesn't happen with 2.4.1 - https://cdnjs.cloudflare.com/ajax/libs/dashjs/2.4.1/dash.all.min.js

This works fine and doesn't exhibit the same bug. additionally, it has far less debug "spam" in the console.

Unfortunately it even happens with 2.4.1 (and lower versions). That's just a matter of being "lucky" enough and do the seek at the right timing. I am currently working on a fix that will share with all of you for testing as soon as it is ready.

Thanks for all the detailed feedback
