We're having the same issue. Our platform has been using video.js since version 6 to load Facebook DASH preview video and we can't make it work. Upgrading to latest version available v7.3.0. doesn't help neither.

Video plays for few seconds and then stops triggering the "waiting" event. Putting the same live video on other players that support DASH works though. Please provide some guidance ASAP.

We get same experience when using the demo: https://videojs.github.io/http-streaming/ with same DASH live stream coming from Facebook Live.

Here's the log we're seeing when initialising and then having playing stalled after few seconds playing.

@gkatsev @heff could you provide some guidance here?

This is being urgent for our platform. We have been using videojs for the last year without issues but then DASH started having issues without doing any change, and updating to latest version of videojs 6.12.1 + dashjs 2.9.2 or upgrading to v 7.3.0 is not working at all.

Stream starts playing but then stops after few seconds and can't resume.

I am also facing some issues like
#260

[amtins]

I updated the ticket to the latest version of video.js. I also fixed the livestreams URL as the previous one is no longer available.

[Nachompiras]

Some fix for this bug?... I am also facing the same issue. :( videojs 7.4.1

[ldayananda]

I also observed with reference streams:

• https://livesim.dashif.org/livesim/segtimeline_1/testpic_2s/Manifest.mpd (gets stuck around currentTime = 301
  • refreshes MPD but does not continue requesting segments
• https://livesim.dashif.org/livesim/mup_30/testpic_2s/Manifest.mpd
  • this has minimumUpdatePeriod of 30s so takes longer to get stuck
  • refreshes MPD but does not continue requesting segments

Observed with latest version on 1.9.0 with Video.js 7.4.0 on https://videojs.github.io/http-streaming/.

I did not quite get enough time to pin down the cause of this, but it looks like the minimumUpdatePeriod re-requests the MPD and updates that reference but does not trigger any media playlist changes. The SegmentLoader then seems to either be looking at older data or trying to only request the last segment and bailing out. That said, I'm not 100% clear on why this is happening.

Same problem with dynamic .mpd file (videojs 7.4.1)
Manifest (1).txt

[SanatSharma]

Facing similar problems with videojs 7.6.6

[gkatsev]

We've updated our README with this as a known issue (https://github.com/videojs/http-streaming#dash-assets-with-time-interpolation-and-segmenttimelines-with-no-t), unfortunately, it will take a while before we are able to address this issue.

[michaelmassee]

Confirmed, waiting to be Fixed.

[skyVerr]

Also having similar problem. Waiting for the fix.

i switched to Clappr - > Shaka Player. Works Perfect

[mrvini]

are there any updates on this issue?

[gkatsev]

Not really. We still don't support stream with $Time$. We did have an issue we found with other live DASH that we're fixing here #1065.

[BucherTomas]

@gkatsev Does this issue concern truly live streams only? The comment https://github.com/videojs/http-streaming#dash-assets-with-time-interpolation-and-segmenttimelines-with-no-t does not say.

I've tried with a couple of VoD assets with latest video.js and they appear to be working just fine even though they fall into the same category by using SegmentTimeline, $Time$ template and d atttribute.

We're contemplating updating to video.js 7 with http streaming and we'd like to know if it's affecting VoD assets as well from your point of view. If not, it might be beneficial to update the comment in known issues.

[gkatsev]

We've generally seen VOD work fine, though, I haven't seen VOD using $Time$. Live DASH is definitely where most of our issues lie.

[gkatsev]

I believe #1231 fixes a lot of issues with Live DASH. Specifically, I can confirm that https://wowzaec2demo.streamlock.net/live/bigbuckbunny/manifest_mpm4sav_mvtime.mpd works now.
We'll have a new release of VHS and Video.js with it soon.

Also, I see that $Time$ is actually working now with #1231, but I think that's more incidental. It still logs lots of warnings in the console in when $Time$ is used.

[gkatsev]

I believe this is now fixed in the latest Video.js/VHS release of 7.18.0 for Video.js and 2.13.1 for VHS.

[amtins]

@gkatsev I think so too, I did a quick test and it seems to work like a charm, thank you that's awesome 🚀 👍
Release note v2.13.0
