Playback fails with dynamic multi-period mpd with xlink

wilaw commented 5 years ago

Environment

[x] The MPD passes the DASH-IF Conformance Tool on https://conformance.dashif.org/
[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://vm2.dashif.org/livesim-dev/periods_60/xlink_30/insertad_1/testpic_2s/Manifest.mpd
Dash.js version: nightly 2.9.3
Browser name/version: Chrome 70
OS name/version: Mac OS

Steps to reproduce

Play http://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/index.html?url=http://vm2.dashif.org/livesim-dev/periods_60/xlink_30/insertad_1/testpic_2s/Manifest.mpd

Observed behaviour

Stream starts but then at period boundary throws Error Dash.js :27 "http://vm2.dashif.org/livesim-dev/periods_60/xlink_30/insertad_1/testpic_2s/BBB_32k_105.mp4 is not available"

Note that livesim response for 105.mp4 returns 404 and indicates "Bad nr of representations: 0"

Is this an error in livesim generator or dash.js? Manifest passes conformance tool.

Hi @wilaw ,

I made some tests with former versions of dash.js : the issue is already there. According to me, it happends before period transition on a 'xlink' period. Some segment requests are in 404 error with the error you described before....

Problem still occurs in v 3.1.1 , might be related to multiple MPD reloads before playback of the Xlink period. After each MPD reload the period id of the resolved Xlink period changes. Needs further investigation.

@wilaw @TobbeMobiTV I checked this stream again changing the url to https://livesim.dashif.org/livesim/periods_60/xlink_30/insertad_1/testpic_2s/Manifest.mpd . The link to the Xlink resolver is not valid anymore: http://vm1.dashif.org/dynamicxlink/ad.php?id=6_ad . Can this be fixed?

wilaw commented 4 years ago

Since https://livesim.dashif.org/dynamicxlink/ad.php?id=6_ad doesn’t respond either, this requires a change to livesim application, which will requires @TobbeMobiTv’s attention.

Cheers Will
