[Feature request] Preload

[Ludotrico]

Pre-loading is a common use case these days because users expect videos to load instantly in scroll views.

API Details:

• GLOBAL: preloadByteCount: specify how many bytes at the beginning of the URL to preload.
• GLOBAL: queueMax: Max number of URLS in the preload queue, if this number is reached upon insertion, remove previous URLS to make space
• DYNAMIC: networkTaskMax: Max number of concurrent network tasks for preloading at any given time. This is necessary to avoid binging client bandwidth and avoid blocking iOS threads.
• preload(urls: Array): add the following urls to to the pre-load queue. Make space in queue if queueMax is reached. ONLY preload if:

1. the current video playing has sufficient play buffer due to good network. If this is not the case, wait until it is to preload.
2. the networkTaskMax has not been reached.

• stopPreload(urls: Array): remove urls from pre-load queue and stop associated data tasks immediately. Extremely useful if user back out of page for example.

Let me know if you need help implementing these. Should be relatively straightforward.

Please try this:
playerManager.isEnableMediaCache = true

@FoksWang I have, this will cache but not preload.

[FoksWang]

I understand what you mean. Indeed, this library has no preload features.

[Ludotrico]

@FoksWang any intention of adding it? I could help.

[FoksWang]

@Ludotrico preload is a good idea, especially for the short videos, I can add this feature, and I will mark it to remind myself. However, in terms of time, I am not sure when I can start to do it, because this year is too busy for me.

[Ludotrico]

@FoksWang I must ask you, why not make your library open source so that others can improve it when you don't have time?

Also, if you do start working on this preload feature, please reach out to me or to a developer that understands the use case well to specify requirements. For example, keeping track of URL tasks and cancelling preloads is extremely important in a tik-tok like video application where videos are in a scroll view.

@Ludotrico First of all, thank you very much for you want to add more features to this library. I created this library to verify a commercial project in the beginning. The commercial code provides CocoaPods support and guarantees that the source code still belongs to the company (private), which is why it is not open source.

I am working on another media project right now this year, so I will just do some bug fixes. New features will not be added until my media project has reached a stage.

Unless fatal issues, it is not the first priority, please understand.
