BTW i have 50 as value for CC3 but not sure to properly set it to 50 only for CC3

@Iragne from what I understand, segmentLimit is used only for live playback (check segment_template.js file).

Yeah, I appreciate this, but I think we have to be careful with a change to the default for all of Chromecast. In particular because we push out new Chromecast SDKs (and their default Shaka versions) in a way that impacts all apps globally, even the ones who have no awareness of what's happening under the hood. It's different when you build your own app and integrate the Shaka Player version of your choice directly.

To be clear, I'm not saying "no" to this, but I think I need to be a little more careful before releasing this change. I think it may need to be coordinated with limits to the availability window, because the initial segment limit only changes what happens at startup, not what accumulates over time. Also, we may want to consider combining these low-memory-related changes into a single flag. Maybe Chromecast Gen 3 isn't the only device that could benefit, so maybe we enable that flag by default for many different device types. And also we might want to avoid that flag by default for newer Cast devices with more memory and higher speeds.

@tykus160 maybe I'm wrong but it's used only under context of } else if (info.segmentDuration) {.
it's true when VOD. I'm happy to double check this again.

@joeyparrish I agree with your approach. And that is true for other devices such as PS, some Tizen, Setupbox, and nesthub...

I'm happy to get all your feedback and propose another approach. I will check how i can combine it with other parameter and devices.

May i can ask how i can properly distinguish the default Chromecast SDK integration compare to the custom one ?

I'm not sure what you mean by that.

Sorry for the late answer.

Reading you comment, I understand you would like to make the difference with the shaka player directly avaiable in chromecast compare to a custom cast reciver. Am I wrong ?

if it's the case, we should need to be able to differentiate the 2 use case and i'm not sure to properly know how to do it.

@Iragne, sorry for being unclear. I'll try to clarify what I said before:

1. When you propose a change to a default setting that will affect all Chromecast playbacks, we have to be careful. Very simply, we have to be careful. The default player config for the default player version used in CAF will affect a lot of apps that won't know the details.

2. The initial segment limit only impacts what happens at startup. It limits the number of segments we parse at first. The availability window, if bigger, will allow more segments to be added to the list later. This means initial segment limit is not the only setting you need to limit segment memory. You also want to carefully limit the availability window.
   availabilityWindowOverride will let you do this, but if used naively, it can also increase the window size.

3. If we want to limit memory, we should maybe only do it for certain devices or models. Or, offload model detection to the app and have a "low memory" flag that tunes various defaults or places other limits. CAF could set this flag based on the model of the Chromecast receiver device.

Closing due to inactivity. If the author would like to continue this PR, they can reopen it (preferred) or start a new one (if needed).

Clear sorry i was working on other stuff. Thanks @joeyparrish
I will rework that later
