I’m using the official Shaka Player demo app.

Yes

What are the manifest and license server URIs?
https://aktd.storage.googleapis.com/static/shaka-tests/merged.mpd

What configuration are you using? What is the output of player.getNonDefaultConfiguration()?
{
"manifest": {
"dash": {
"clockSyncUri": "https://time.akamai.com/?ms&iso"
}
},
"preferredAudioLanguage": "en-US",
"preferredTextLanguage": "en-US"
}

What did you do?
1- Open the URL in Chrome
2- Waited for ABR to trigger a bitrate change or period change (network throttling speeds this up).
3- Observed that playback stalls and no further segments are downloaded

What did you expect to happen?
Playback should continue seamlessly and download the next video segments at the newly selected bitrate by ABR without stalling.

What actually happened?
I merged two DashIF example manifests:

1. Multi-period (SegmentTemplate@duration):
   https://dash.akamaized.net/dash264/TestCases/5a/nomor/1.mpd
2. Single-period (SegmentTemplate@duration):
   https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd

The merged MPD uses:

• Period 1 from the multi-period MPD
• All content from the single-period MPD
• Period 2 from the multi-period MPD

I then updated the MPD’s total playback duration.
While DASH.js plays this merged MPD without issues, Shaka Player stalls whenever ABR switches bitrate and again when transitioning between periods, ceasing to download any further segments.

Are you planning to send a PR to fix it?
Don't know how to fix

Hi All,

I just found that version 4.4.3 works fine.
The latest version is not working correctly.

I am still investigating the issue with latest version.
