Please ask your question

On the following devices, we experience playback freeze with the default shaka configuration on the simple big buck bunny.
The only option to make the stream play until the end was to initialSegmentLimit at 50.

Today we are not 100% sure of this impact but it clearly solve our issue on low performance devices.

My questions are the following

• What should be a correct value and what is the impact of this initialSegmentLimit at 50
• Second, should we set automatically that value at 50 for those following devices

manifest.dash.initialSegmentLimit limits how many segments are generated in memory during the initial parsing of a DASH manifest. You may lower it to reduce startup memory at the expense of the amount of content that can be seeked on startup of a live stream. You may also want to consider manifest.availabilityWindowOverride, which limits the seek range. These are both for tuning live content.

Does this help?

Thanks @joeyparrish Yes we are considering it for live. My point was, should we set manifest.dash.initialSegmentLimit to a low value for any Chromecast platform by default. Today on Ultra cc3 ..., we can't even play a vod with default setting.

Happy to release a PR if needed
