Video Load VideoClip in assetbundle on Android

Hi,

I have some problem to get my assetloader work on Android. I try to load VideoClip from assetBundle. It works great on editor but when i try this small piece of code on Android I have this error in my logcat.

The code :

Code (CSharp):

1.        
2.  
3.         videos = bundle.LoadAllAssets<VideoClip> ().ToList ();
4.  
5.         var go = new GameObject ();
6.         var player = go.AddComponent<VideoPlayer> ();
7.         player.renderMode = VideoRenderMode.CameraNearPlane;
8.         player.targetCamera = Camera.main;
9.         player.audioOutputMode = VideoAudioOutputMode.Direct;
10.         player.clip = videos [0];
11.  
12.  

The error :

Do i need to do some other work to get my videoClip on Android ?

Thanks in advance for your help

Blist

 

I got same problem too. Has solved it?

 

me too !!

 

Hi,

I've send an issue to the unity team and this is the anwser :

Hey,

Thanks for reporting the issue.

In https://unity3d.com/jp/unity/whats-new/unity-5.6.0 release notes it says that this feature was not yet implemented. So it is expected behavior to throw an error. As for now, You can simply keep following up with newest unity releases and check if the feature was implemented in newest unity versions.

QA Team​

In fact in the 5.6 release note :

The Android VideoPlayer cannot yet read videos from asset bundles.
​

 

I am sorry to hear that. I have been searching for 2 days.
is there any other soulution we can use?
thanks

 

Hi, I read on the video documentation draft that videos are now compatible with assetbundles (look attachment or documentation link).
Is this feature already confirmed with the current version or will it be scheduled in the next release?

 

Any Update on this ?
I try to load a movie from an assetBundle (The AssetBundle Loader is tried and tested).

When I try to load a movie I get the reference (I can see the VideoClip in inspector and get its info) but when I try to play it I get following error:
WindowsVideoMedia error 0xc00d36c3 while reading archive:/CAB-079738cb4484a886591221850bcc2bec/CAB-079738cb4484a886591221850bcc2bec.resource

5.6.2p4 videoplayer from bundle still does not work

 

2017.1.0p3 videoplayer from bundle does not work

 

5.6.3f1 videoplayer from bundle does not work

 

2017.2.0f3 videoplayer from AssetBundles still not working.

 

Does iOS also exist this problem?

 

Is this still an issue? And if yes is there any workaround?

EDIT: Does not work on v2017.2.0f3

 

Ye,same

 

Tested it on v2017.1.2p3 as well but it still doesnt work.
Same output:


AndroidVideoMedia OpenExtractor unable to open archive:/CAB-14baa5416d7d039303ccd3f472c5d1c1/CAB-14baa5416d7d039303ccd3f472c5d1c1.resource, error: 2

• Video: Fixed clip from asset bundle not played. (964652)
  
  Some things in the patch notes of Unity 2017.2.1

 

I hope the Unity team will fix the problem as soon possible since many people are having issue with it.

 

Sigh, same issue here, and I'm using 2017.2.1. Video doesn't playback on android.

 

the same problem。not fixed in 2017.2.1
temp load from resources

 

I have the same problem too. And finally I found that we can use VideoPlayer's url to resolve this question.Download .mp4 file from remote url and save to persistentDataPath then set the path to VideoPlayer's url.This can work well on Android and IOS both.

 

I thought of an idea, the idea is to save the assets from the assetbundle to the resources folder then loading those assets from resources

 

and still in 2017.3
even if the video is in a sean and the sean is in a asset bundle , same thing

 

Confirmed still broken in 2017.3. video/asset bundle issue on android

 

On the 05.12.17 i received a reply from unity in which they were saying the following:
"
...Video from Assetbundles is not (yet!) supported on Android. : (

It is on our roadmap though!
https://unity3d.com/unity/roadmap
"Video: Android Asset Bundle Support"

Sorry for the inconvenience, but all I can say is that we are working on it : )"

I really hope they are working on it to release it in the coming few versions (2018.1 would be great D).
Just wanted to share the information for everyone in here waiting for the "issue" to be resolved.

 

I've downloaded 2018.1 beta and this issue still isn't fixed. Does anyone know if there's a timeline for fixing this?

 

If you have read the previous post you should know It's not that this seems to be a bug. Its just not supported yet but hopefully is coming in future builds.

But if you are interested, I have written a workaround for this not using the asset bundle system but a custom system which uses zip archives. If I can find some time I'm going to make my source public and post the link here as well.

 

Hi Desoxi,

Would it be possible for you to share the workaround? Thanks so much!

 

I read somewhere on these forums (forget now) that it can actually work if you're using uncompressed asset bundles for the videos. I think the compression on the asset bundle is messing up the video codec compression. Not sure though

 

Thanks so much for the info! Yes! It works fine without compression.

 

I have similar problem on some devices. Can't reproduce it locally but analytics show that i have about 10% from deaily users reports about this problem.

Will try to disable compression. Thanks @CDF

 

But i have a scene with a videoplayer and a movieclip put all together in 1 assetbundle. Even when i use :

BuildPipeline.BuildAssetBundles ("Assets/Bundles/Android Bundles", BuildAssetBundleOptions.UncompressedAssetBundle, BuildTarget.Android);

The movie is not played on Android. On iOS everything worked perfectly. So JessicaLee88 how did you do this?

 

The difference appears to be in how you store and read from the bundle. In the latest 2018 betas it should work with uncompressed bundles, as long as the bundle is stored locally instead of being read from cache / memory (probably using https://docs.unity3d.com/ScriptReference/AssetBundle.LoadFromFile.html)

 

Hey, multimediamarkers,
Just saw your question. Hope the answer is not too late. The options I was using are as follows: BuildAssetBundleOptions.UncompressedAssetBundle and BuildAssetBundleOptions.ForceRebuildAssetBundle. Also make sure you load the movie locally rather than from cache/memory. That should work with 2018 beta. It will not work with 2017.3.

 

Something in the last beta update :
Video: Support for reading videos from AssetBundles on Android.

Not tested yet.

 

As posted above, works when reading from local bundle that is not compressed.

 

Does anyone has a script example how to load a movie file locally after it is loaded from an AssetBundle on an Android device?

 

This loads a streamed scene which contains a videoplayer and videoclip (and it works on android).

If you want to load the clip itself from a bundle instead of include it in a scene, just load it from bundleFile after LoadFromFile and assign it to the clip property of the VideoPlayer component.

Code (CSharp):

1. string filePath = Path.Combine(Application.persistentDataPath, "videoplayer");
2.  
3.                 DownloadHandlerFile dh = new DownloadHandlerFile(filePath);
4.  
5.                 UnityWebRequest requestFile = UnityWebRequest.Get(url);
6.  
7.                 requestFile.downloadHandler = dh;
8.  
9.                 yield return requestFile.SendWebRequest();
10.  
11.                 if(!requestFile.isHttpError && !requestFile.isNetworkError)
12.                 {
13.                     Debug.Log("Download complete, attempting to load bundle.");                
14.  
15.                     AssetBundle bundleFile = AssetBundle.LoadFromFile(filePath);
16.  
17.                     SceneManager.LoadScene(bundleFile.GetAllScenePaths()[0]);
18.                 }
19.                 else
20.                 {
21.                     Debug.LogError(requestFile.responseCode + ": " + requestFile.error);
22.                 }

 

Unity 2018.1.0f2 and can't play clip from bundle in Android. Will try saving video to persistentDataPath

 

@JessicaLee88 hai jessi, i have similiar problem when load video in assetbundle, may i know your unity version when load video as assetbundle?. I have been tried in 2018.1 and compiled to android, and still not working. And when i try to download seperate file video only to persistentDatapath, it does not work too. But in editor works fine. Today i will try to uncompress the assetbundle, and post the result. ohh, by the way, i used Assetbundle browser to handle assetbundle, it makes me easy to manage assetbundle. Thanks before

 

I've been emailing back and forth with the Unity Q&A team and it's now marked as a bug

https://fogbugz.unity3d.com/default.asp?1033212_9g4t887dash6pcn2

 

Hey, Prasetion, I am using the latest 2018.1.0f2 release with uncompressed asset bundle. Videos load very smoothly. It won't work with any previous versions of Unity.

 

Hey, nilsdr, Thanks for logging the bug with Unity team for all of us!

 

Same problem/error on webgl too (using 2018.1.4f1)!

 

Hi nilsdr,

Thank you very much for sharing your code. Unity has been going through a lot of changes recently with regards to assetBundles and I am struggling to find/implement up to date code that will not be deprecated within the near future, regarding assetBundles as I try to implement it in my code. I was wondering if you might have a sample of your above code using assetBundles along with the hash/caching system?

Thanks in advance!

 

How do you use both of those settings? it only takes that argument once

 

This is still an issue for me in Unity 2018.2.5f1.

Has anyone found a solution? I should be able to just download the assetbundle with the video, assign it, prepare it and play it, but it wont play.

Any help is really appreciated!!

 

I am doing a Vuforia Augmented Reality app and I am using a video with a green screen. I use a Chroma Key tool from the Asset Store to key out the background.

Everything works perfectly in the editor and on my android -- HOWEVER, when I try to download and load it from an asset bundle it does not work.

It think I should be able to download videos from an asset bundle. Seems like a basic feature that everyone should be able to use. If it is not working or available, it should be fixed asap. Please!

 

Does anyone know if this is fixed yet? Loading videos from asset bundles is really a must have.

 

Let me end this issue.
Firstly, thanks for all the answers above. After my try and try and try. I finally found the solution.
To make VideoPlayer that packed into an AssetBundle works fine on Android platform, there are two key points you have to take care.

First, use BuildAssetBundleOptions.UncompressedAssetBundle to build your AssetBundles.

BuildAssetBundleOptions options = BuildAssetBundleOptions.None;
if (target == BuildTarget.Android)
{
options = BuildAssetBundleOptions.UncompressedAssetBundle;
}
else if (target == BuildTarget.iOS)
{
options = BuildAssetBundleOptions.None;
}
BuildPipeline.BuildAssetBundles(outputFolder, builds, options, target);

Second, use AssetBundle.LoadFromFile() to load your AssetBundle instead of using WWW.

string path = Application.persistentDataPath + "/" + assetBundleName;

AssetBundle bundle = AssetBundle.LoadFromFile(path);

GameObject prefab = bundle.LoadAsset<GameObject>(assetName.ToLower());

That's all. On iOS platform, you can still use WWW to load your AssetBundle.

By the way, the Unity Editor version I use is 2018.2.12f1.

Finally please allow me to introduce my personal Unity Project - Racing Liberty. It's a 3D mobile racing game. You can download it on Google Play Store now. The iOS version is under reviewing and will coming soon. Have a try.

 

Please do not get me wrong!
Your solutions seems to be the first candidate that could really work!
Believe me, I did also a lot of testing and trying - and found no for me working solution.
So thank you for your effort and the fact that you are sharing your findings!!!

On the other side:
Not using

using (var www = WWW.LoadFromCacheOrDownload(url, ...)) { ... }

means loosing all caching benefits.

"...LoadFromFiles(...)" is a blocking operation. Ok we can use "LoadFromFileAsync(...)" to solve this ...

But the unity docu says that both methods are requiring a "Path of the file on disk."
This means that the asset bundles must be copied first "somehow" to the mobile device.
My goal is that they are stored on a public web server; keywords: Maintenance, changing content (=asset bundles) while the app (=apk in this case) must not be changed ...

Seems finally that we have to wait until Unity is fixing this!
Or do I miss something?

But as said:
Thxs 4 u effort and sharing! Great work!!
