Hi I’m asking for any assistance with regards to preloading and caching the videos in NET Maui particularly on Android. On iOS, it takes literally 2-3 seconds to load and instantly play the Video but takes roughly 15-20 seconds on Android. Is this an issue with Exoplayer or is there any code that I should add in order to make my App more performant for Users? The videos are on Azure Blob Storage!

Yonglun Liu (Shanghai Wicresoft Co,.Ltd.) 50,126 Reputation points Microsoft External Staff2023-04-18T07:37:01.29+00:00 I tested it in Android using an online video and
MediaElementon my device: Android 11, 12, 13 emulators are within 5s from loading the video to starting playback.Could you please provide the following details?
- Your MAUI version and Android API level.
- If you use a video test link that doesn't require authentication, will Android still load for a long time?
- In addition, you could implement a caching mechanism using
ExoPlayerinMediaElementvia the following code:
MediaElementHandler.PropertyMapper.AppendToMapping("subtitleMapper", (handler, player) => { #if ANDROID var s = handler.PlatformView.GetFirstChildOfType<StyledPlayerView>(); var Exoplayer = s.Player; #endif }); -

2023-04-24T13:39:49.25+00:00 Maui is 7.0.81 Android APIs are 31, 32, 33
- If you use a video test link that doesn't require authentication, will Android still load for a long time? Yes but on iOS is loading quite faster all the time. Here is a video link to test perhaps on your side... The code provided for caching mechanism, where do I place it exactly?

2023-04-24T14:12:46.62+00:00 Another thing about this Code, it point to "subtitle" and I don't understand why as it seems like this Code is incomplete. I've looked at a way to cache these Videos but could not find a clear direction for MAUI.

You could refer to Customize controls with handlers to use the code snippet.
The function of the above code snippet is to show how to get the Android native
ExoPlayerclass fromMediaElement, and then you can refer to the article How to preload and cacheExoPlayerin native code to implement it in MAUI.The parameter "subtitleMapper", is a key name that you can change it.
You could refer to CommandMapperExtensions.AppendToMapping<TVirtualView,TViewHandler> Method for more details.
key String The name of the command.
