When i looked to how the player is behaving against bandwidth changed i found that the network engine was sending wired information to the ABR manager

Segment downloaded: contentType=video deltaTimeMs=5 numBytes=132328 lastTimeChosenMs=1715701213390 enabled=true

Segment downloaded: contentType=video deltaTimeMs=153 numBytes=71224 lastTimeChosenMs=1715701213390 enabled=true

Segment downloaded: contentType=video deltaTimeMs=604

deltaTimeMs=5 so much data in so short time is quite wired to me. is that something possible can it be linked to wrong information.
have you experience it ?

Should we put some filter to avoid to count that value inside the ABR manager

additionally we are only passing information of the bandwidth during the on-progress and never at the end of the download of the segment. I'm wondering if we should also add it when the download is ended. event if it's kind of duplicate

here the end of the request

shaka-player/lib/net/networking_engine.js

Line 577 in 4a41a9a

if (connectionTimer) {

here the way it's calculated in the on progress

Browser caching could explain bad data being fed to ABR manager. Can you try again with caching disabled/cleared in your browser?

@joeyparrish sorry i should mention this but the test had been done with cache disable on FF

We should use something like https://github.com/Dash-Industry-Forum/dash.js/blob/development/src/streaming/models/ThroughputModel.js#L250

Since I want to make improvements to the ABR, I assign it to myself and move to improvement.
