Stream used
https://d24rwxnt7vw9qb.cloudfront.net/v1/dash/e6d234965645b411ad572802b6c9d5a10799c9c1/All_Reference_Streams/ee565ea510cb4b4d8df5f48918c3d6dc/index.mpd

I'm playing a stream multi period live manifest.
I'm bock the playback to only 1 quality to reduce to complexity of the investigation
During the playback i have a lot of GAP that are 4 to 15 second long. it's not making any sense.
Also i compare it to a chrome of an FF playback, i not so much GAP and at that size.
[Info] Jumping forward – 6.088022217154503 – "seconds because of gap starting at" – 113149184.372666 – "and ending at" – .....

I'm a bit lost in the investigation
I did a support with
shaka.polyfill.MediaSource.stubAbort_();
and shaka.polyfill.MediaSource.patchRemovalRange_();
Also set the canUseNativeMCap to false

But i have a lot of GAP apearing and at the end i reach the edge of the playback
Any guidance ?

Could it be a bug in WPE? If it's truly equivalent to Safari 8, as the UA implies, we stopped supporting that long ago. You can go through the history in lib/polyfill/ to a time when we still supported it, and see the various workarounds and bans that were required.

Yes i was thinking about this too.
Thanks for the lead.

During my test i figure out that when we are jumping Gap we just going close to the edge.
At the end, we are so close to the edge that when we are jumping a gap we enter in the following condition of the playhead repostion_ function

if (currentTime > end) { shaka.log.v1('Playhead past end.'); return endl; }

end is the seakable duration but we are kind of looping to this value all the time.
should we not do more something like that

if (currentTime > end) { shaka.log.v1('Playhead past end.'); return end - this.config_.bufferingGoal; }

@joeyparrish you refer to that 6ae1474

[joeyparrish]

No, but that may also be relevant. I was referring to the polyfills. I dug up this commit, for example:

8c7c74e#diff-7f8f8933c7e0846befae7dec87bf7548d4569126806688c6ff2c0f2619260c9bR54
