    Check the logcat for errors.

    This is the function used to stream bundle and assigned to video player, from getting the clip.
    Code (CSharp):
    1. public IEnumerator GetAssetBundle(string filePath)
    2.     {
    3.         //Download everytime
    4.         //UnityWebRequest www = UnityWebRequestAssetBundle.GetAssetBundle(filePath);
    5.         //Re-load cache
    6.         Debug.Log("filePath - "+ filePath);
    7.         UnityWebRequest www = UnityWebRequestAssetBundle.GetAssetBundle(filePath, 1, 0);
    8.         yield return www.SendWebRequest();
    9.  
    10.         if (www.isNetworkError || www.isHttpError)
    11.         {
    12.             string errorMsg = "Error download - " + www.error;
    13.             Debug.Log(errorMsg);
    14.             ShowMessage(errorMsg);
    15.         }
    16.         else
    17.         {
    18.             ShowMessage("Downloading bundles");
    19.             AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(www);
    20.             loadedBundle = bundle;
    21.  
    22.             VideoClip video = loadedBundle.LoadAsset<VideoClip>(videoAssetName);
    23.             videoPlayer.clip = video;
    24.             videoPlayer.Play();
    25.  
    26.              ShowMessage("Download completed");
    27.             StopAllCoroutines();
    28.         }
    29.     }

    Can you switch to Development build, since Release, has limited output to logcat?

    Also can you show, how are you calling GetAssetBundle ?

    Hi Tom, There is no error displays in log, even build is in dev mode. I have attached the source and log details here along with the script used to stream assets. Bundles are created in uncompressed format, it is available with source. Source also have details of URL where bundles uploaded and name of the video I am streaming in. Please do check, it is a show stopper for me from releasing the app.

    Ben

    In the logcat it still says 'Release', can you attach logcat from Development

    Not sure if it will work, but did you try requesting a video file instead of a bundle and access that instead?

    Any update on this issue? I have similar problem. I am using Unity 2020.3.8.

    I need to play video from Streaming assets (because it will be downloaded from server). Video has alpha channel, so i tried using VP8, but i found out that Android doesn't support it, so Unity has to transcode it. That means i can't play directly from Streaming assets, so i made AssetBundle. This assetbundle can be in Streaming assets, and everything works perfectly (alpha channel also) - using Mono (ARM v7).
    But when i use IL2CPP i can't load video.

    Am i stuck with Mono?
