[Android] Caching feature does not work

[dw8869]

Caching not wokring on Android.

• Unity version: 2020.3.32f1
• AVPro Video version (number and edition (trial/core/ultra/enterprise)): 3.0.4 Ultra
• Operating system version: OS 12
• Device model: Galaxy S10 5G

1. Call AddMediaToCache
2. Check GetCachedMediaStatus
3. Progress value does not increase.

1. Is it reproducible in a new project with just AVPro Video?
2. Are you using the Exoplayer API?
3. What media are you trying to cache?
4. Can you send us a URL that you have used for testing. Either here or to unitysupport@renderheads.com
5. Can you provide a full logcat in txt form

[dw8869]

1. Yes.
2. Yes. Caching feature only supported when using the ExoPlayer API.
3. HLS Media.
4. https://mediapoccdn2-standard-ms-ams.azureedge.net/44b022b1-9a02-438e-a511-bbae448e8259/bd72fbdb-f539-4f0e-ac99-4fb69242.ism/manifest(audio-only=false,format=m3u8-aapl-v3).m3u8
5. logcat2.txt

It worked fine with AVProVideo v2.9.x. Here is my test code on DemoScene.

private IEnumerator Start()
{
    // wait for create player.Cache.
    while (player.Cache is null)
    {
        yield return null;
    }

    player.Cache.AddMediaToCache(url);
    player.OpenMedia(new MediaPath(url, MediaPathType.AbsolutePathOrURL), true);
}

public void Update()
{
    if (player != null && player.Cache != null)
    {
        float progress = 0f;
        var status = player.Cache.GetCachedMediaStatus(url, ref progress);
        Debug.Log($"GetCachedMediaStatus: {status} / {progress}");
    }
}

Thanks for reporting this.

We will have this fixed in the next release (v3.0.5).

If you wish to apply a fix to your current working copy of the asset, then you can simply modify some script code...

NOTE: This script change will break iOS caching. Naturally they will both be in a working state for the next build we release.

#if !UNITY_EDITOR && ( UNITY_IOS || UNITY_ANDROID )
    // Media Caching
    public sealed partial class PlatformMediaPlayer
    {
        public override bool IsMediaCachingSupported()
        {
            return true;
        }

        public override void AddMediaToCache(string url, string headers, MediaCachingOptions options)
        {
            Native.MediaCachingOptions nativeOptions = new Native.MediaCachingOptions();
            GCHandle artworkHandle = new GCHandle();

            if (options != null)
            {
                nativeOptions.minimumRequiredBitRate = options.minimumRequiredBitRate;
                nativeOptions.minimumRequiredResolution_width = options.minimumRequiredResolution.x;
                nativeOptions.minimumRequiredResolution_height = options.minimumRequiredResolution.y;
                nativeOptions.title = options.title;
                if (options.artwork != null && options.artwork.Length > 0)
                {
                    artworkHandle = GCHandle.Alloc(options.artwork, GCHandleType.Pinned);
                    nativeOptions.artwork = artworkHandle.AddrOfPinnedObject();
                    nativeOptions.artworkLength = options.artwork.Length;
                }
            }

            Native.AVPPluginCacheMediaForURL(_player, url, headers, nativeOptions);

            if (artworkHandle.IsAllocated)
            {
                artworkHandle.Free();
            }
        }

        public override void CancelDownloadOfMediaToCache(string url)
        {
            Native.AVPPluginCancelDownloadOfMediaForURL(_player, url);
        }

        public override void RemoveMediaFromCache(string url)
        {
            Native.AVPPluginRemoveCachedMediaForURL(_player, url);
        }

            public override CachedMediaStatus GetCachedMediaStatus(string url, ref float progress)
            {
            return (CachedMediaStatus)Native.AVPPluginGetCachedMediaStatusForURL(_player, url, ref progress);
            }
    }

Wow, thank you so much. I'll test it.

@Ste-RH I tested your code, caching is works fine. But, does not received FirstFrameReady.
