Dash.js: v2.5.0: VOD does not play through until end

Created on 28 Apr 2017 · 23Comments · Source: Dash-Industry-Forum/dash.js

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://dashif.org/reference/players/javascript/ and not just on my page
Link to playable MPD file: http://edge.flowplayer.org/night4.mpd
Dash.js version: v2.5.0
Browser name/version: all browsers I have tested so far
OS name/version:

Steps to reproduce

Go to http://dashif.org/reference/players/javascript/v2.5.0/samples/dash-if-reference-player/ and play http://edge.flowplayer.org/night4.mpd
May sometimes not happen if stream is cached, so cache-refresh before testing.

Observed behaviour

Stops before end instead of looping.
Does not happen e.g. at http://dashif.org/reference/players/javascript/v2.4.1/samples/dash-if-reference-player/ or below.

EDIT: updated with completely conformant stream.
Conformance: similar streams - presumably the problem is related to stream ending on segment border - either now pass conformance (edge.flowplayer.org/night[1-6].mpd) - or in one case (edge.flowplayer.org/night7.mpd) fail on the first 2 representations with:

Warning: Unknown atom found "pasp": video sample descriptions would not normally contain this
WARNING: unknown mvex atom 'trep'
WARNING: unknown/unexpected atom 'meta'
### error: 
### Buffer underrun conformance error: first (and only one reported here) for sample 1 of run 1 of track fragment 1 of fragment 9 of track id 1 (sample absolute file offset 127648, fragment absolute file offset 127316, bandwidth: 121008)

Which seems weird as all 7 are encoded the same way.
But issue is there regardless of conformance, and 2.4.1 works fine with all of them, even with their previous versions which had more conformance errors like the above.

Bisected several times to 29c0eff76aa84e1d1924c9b71cd7a8514a54e010 as first bad commit.
Disclaimer: take result with a certain amount of caution because browser cache persistence can interfere, but I tried as best as I could

Reverting 29c0eff fixes the problem for me[tm].

blacktrash on 6 Jun 2017

Ping ;-)

Working in nightly - looping each time. Can you try here

dsparacio on 11 Jul 2017

@AkamaiDASH - thanks, but, no, for me it's still the same problem, sorry.

blacktrash on 11 Jul 2017

@AkamaiDASH - did you really try with e.g. https://edge.flowplayer.org/night4.mpd ?

blacktrash on 13 Jul 2017

It works rather well in Chrome, but not 100% reliably, but almost never in Firefox or Safari.

blacktrash on 13 Jul 2017

@AkamaiDASH - if I do the equivalent to reverting 29c0eff on the latest development:

the problem again goes away.

ping ;-) this problem is still present in Firefox 55, and arguably it's somewhat basic.

blacktrash on 8 Aug 2017

It turns out 29c0eff was exposing the problem not causing it. The problem was caused by an incorrect audio buffer target when a video track is present. Before 29c0eff the video track present check was (incorrectly) always returning false, circumventing the real issue. Fixed in #2122.

spiterikevin on 11 Aug 2017

@spiterikevin - indeed your change seems to solve the problem.
Thanks a bunch!

blacktrash on 11 Aug 2017

@spiterikevin - hm, there's still trouble with some streams, for instance http://edge.flowplayer.org/moon.mpd - again, no problem with the revert hack.
Addendum: let's hope it was a caching issue, it seems to work now. I'll keep an eye on it.

blacktrash on 11 Aug 2017

No. It's better, but not as reliable as the "broken" approach, which _always_ works in this regard. Especially in Firefox with empty cache, starting, and jump seeking towards the end.
I _want_ it to work, but ... and otherwise I see lots of improvements, e.g. with multiperiod etc. Pity.
I'll try some more in the next couple of days.

blacktrash on 11 Aug 2017

And when it hangs, the following is repeated over and over in the console:

[Log] [28148] getNextFragment - Playing at the bleeding live edge and frag is not available yet  (dash.all.min.js, line 18)
[Log] [28161] Switch to index 0; buffer is empty.  (dash.all.min.js, line 18)
[Log] [28161] AbrController (video) stay on 0/7 (buffer: 0)  (dash.all.min.js, line 18)
[Log] [28161] ScheduleController - getNextFragment  (dash.all.min.js, line 18)

HTH.

blacktrash on 11 Aug 2017

Interesting. I am reproducing this error, but it is not as consistently reproducible. And I'm also occasionally getting it even with the revert fix. I don't yet understand what's going on and will look into it more.

@spiterikevin - much appreciated.

blacktrash on 11 Aug 2017

@blacktrash I have submitted two related PRs, #2128 and #2130. They are related to this issue. Do they help?

spiterikevin on 15 Aug 2017

@spiterikevin - not 100% sure whether you meant me to test with all 4 patches applied:

but that's what I did, and it seems to solve the issue.

blacktrash on 15 Aug 2017

👍1

@blacktrash Yes, that's what I meant. Thank you for flagging the issue and testing it.

spiterikevin on 15 Aug 2017

@spiterikevin - thank _you_.

blacktrash on 16 Aug 2017

@spiterikevin - I did not follow the fate of your patches closely, but from my perspective all seems fine with v2.6.0.

blacktrash on 4 Sep 2017

@blacktrash, closing this issue as it seems to be fixed. Please, feel free to reopen it in case you can reproduce the issue again.

Many thanks!
