Mobile Movie Texture

Hi Dan,

The crash bug I had is also reproducible in android. We successfully reproduced the problem on a Nexus 5.

Digging further, we have reproduced the crash in an empty project, with only MobileMovieTexture package 2.0.4 imported. We just added a gameobject with a script reloading the current scene every two seconds. However sometimes we have the bug on the first play, even before the script reloads the scene.

Devices : Nexus 5, iPod touch, Iphone 5S
Unity version : 4.3.7, 4.5.1, 4.5.2 (all mac editors)

All devices and Unity versions have shown the bug. Please help us out.

 

Hi everybody!

I have some problems with buttons in MMT. I'm trying to do a 3 personal buttons (like the sample scene: play, pause and stop).
When I click play it starts well, but the first problem is when I click pause button it stops well, but when I click play to start again the video (at the same moment it was stopped) it doesn't start. The same happens whith stop button.

Anybody knows how to do that?

I use this scripts:

PLAY, PAUSE and STOP: (They are the same changing the function):

Code (CSharp):

1. public class BotPause : MonoBehaviour {
2.  
3.     public MovieAudioController movieController;
4.    
5.     void Start()
6.     {
7.      
8.     }
9.  
10.     void OnClick()
11.     {  
12.         movieController.Pause ();    
13.     }
14. }
15.

Thank's everybody!!!

 

All,

Just found something in the MobileMovieTexture.Update(). It was calling DestroyTextures() then AllocateTextures() every frame for every video played. It should have only happened the first time Update() ran.

This line

Code (CSharp):

1. textureContext = m_nativeTextureContext;

means that m_nativeTextureContext will always equal zero.

Should be

Code (CSharp):

1. m_nativeTextureContext = textureContext;

If I'm wrong let me know and I'll edit this post. But, we're no longer seeing the steep memory climb; something that we were assuming was in the native code.

Also, using the Windows Task Manager, I'm seeing that the number of Handles only increases while playing videos on MMT objects in a pool. Leads me to believe that, maybe, file handles are not being closed after an OpenStream().

EDIT: After some further investigation using the handle.exe utility from the SysInternals Suite, it appears that, on a Windows system (no idea about other OSs), every time a video is played with MMT, two Event handles and two Thread handles are opened but not closed. So, for every video played, the number of opened handles increases by four.

 

This is what I want. and I downloaded demo version.
It works when I compiled it on Android phone, but In Unity it said error msg
"DllNotFoundException: C:/a/Assets/Plugins/x86/theorawrapper.dll"
I am using windows7 64bit and unity3d 4.5. And the dll is at the path. I don't know why.

 

Likely, you are missing the MS dependency like it says further up this thread:
http://forum.unity3d.com/threads/mobile-movie-texture.115885/page-7#post-1065001

For version 2.0.4, Google for something like msvcr100 redistributable

 

Hi Dan, got a problem too with new releases of MMT.

I have random crashes on android and IOS.
On IOS it is not happening really often, but on Android it's randomely crash after a few seconds (sometimes a few minutes).

This is the log where I've noticed problems, but was unfortunately unable to know what's really wrong. Tried ndk, addr2line, but nothing worked so far.
I just rolled back to previous version of MMT, and the problem disappeared. Quite a pity cause recent versions of MMT really boost performance and quality of videos. Especially on Android.


This is the log where it says something bad happenend with litheorawrapper.so :

Dunno if it helps.

Good luck !

 

Hi,
I just installed the demo version of Mobile Movie Texture, and when I want to run the testing scenes, I get the same problems as InfoTimeCode on the previous page : pink materials and no videos.

What am I doing wrong ?
Thanks, regards

 

I have the exactly same problem with Unity 4.5.3

 

I have the same problem with the same version as iTris666 has. In my case, I reproduced by modifying TestMobileTexture.cs under sample project MobileMovieTextureTest. For more precise information, I have added

Code (CSharp):

1.  
2.         if (GUILayout.Button("Reload Scene", GUILayout.Height(150), GUILayout.Width(150)))
3.         {
4.             Application.LoadLevel ("MobileMovieTextureTest");
5.         }

in private void OnGUI(). This make I can restart the game scene by clicking on the button.

For the result, I have got crashed In Android ( I have tested in Sony Xperia SP ( Android 4.3 with official ROM), and Sony Xperia Z Ultra ( Kitkat ).

I have attached full crash log for this bugs.

Not only in Android but I also found a bug in iOS ( iPad 2 with iOS 7 ) by reproducing in the same method. The bug result in iOS is "The plugin display nothing but black screen". ( Unfortunately, I don't have iOS log for you, but it should be not difficult for you to reproduce it in any iOS devices )

Moreover, I'm pleased for any question or acquired information.
Thank for your help in advance.

 

OH thanks~!

 

Ahoy,

How would one know if they have v2.0.4 or not? (The "Instructions" doc still says 2.0.0 at the top)

I've downloaded / imported the package straight from the asset store, but i'm still getting a green texture instead of a movie on the "MobileMovieTextureTest" scene on Android (worked fine on iOS & in editor).

 

HI,
How did you create and/or convert your video file with transparency, ExplosionSplitAlpha.ogv?

Thanks

 

Hey! Reall nice tool!

I've purchased the full version, and I'm working on a gallery of videos por android devices, is there any option for when some video stops playing it take me back to a Main Menu?

Thanks and regards!

 

I have installed the last version of the plugin and purchased the license, when I change from one video to another in android I get a green screen before the new video in displayed on the screen, do you know why ????

 

your work is so great~~~~I want to ask Is there possible to play ogv theora encoded videos on a texture in your projects.

 

I've just updated to Unity 4.5.4 and I'm trying out this demo. It works great in the editor on OSX. It does not work on PC editor (wrong dll or something). However when I attempt to link the Xcode project it fails with these errors:

anyone know how to fix this? (it's the only thing currently stopping me from purchasing this plugin)

 

I meet the same issue with you. and here is what i have done, which make my project works well.
on the player setting, uncheck the item of "Use Direct3D 11*"

hope this will help you

 

Didn't work
Anyway, thanks for answering, I'll keep trying this way

 

We are using your plugin version 1.1.4. for iOS with Unity 4.5.4, when our project started on iOS-8/7 it's work fine, but it doesn't work on iOS-6, in the degug console we have:

GLES20: Color Space/YCrCbtoRGB Split Alpha:

GLES20: vprog textures are used, but not supported.

Warning: Creation of shader 'Color Space/YCrCbtoRGB Split Alpha' failed.WARNING: Shader Unsupported: 'Color Space/YCrCbtoRGB Split Alpha' - Pass '' shader state not supported

GLES20: Color Space/YCrCbtoRGB:

 

Seem MobileMovieTexutre dont run on Unity4.6beta, right? Just Green Screen and dont see "StreamingAssets" folder

 

Did you ever get this issue resolved? I am having the exact same problems and am unfamiliar with C#

 

is there any way you could let me know how to define a property for playAutomatically in the MMT class? I am having the same issue as ciooong and know little about c#. very sorry to even ask.

 

Hello,

Our team is having trouble with multiple instances of MMT, and as far as we could notice the problem is a bad memory access from the DLL when it is not totally unloaded.

Is there a way to receive a message from the DLL when it is fully unloaded and the memory is free to start another thread?

Does anyone have a good technique for syncing audio to with this video playback?

 

My team will buy one MMT. But could you comfirm some function can do with mmt.

- can i apply multi video on 1 project?
- can i modify and apply seperate mmt for once plane?

Thanks and Best.

 

Hi Dan,

I've successfully published a game using MMT v1.1.7 on PC and Mac.
Now it's time to go mobile and I've downloaded the newest version of MMT (2.0.4).

I have a problem similar to gkazamias here:
http://forum.unity3d.com/threads/mobile-movie-texture.115885/page-14#post-1691174
and borr a little further up this page.

Namely the following happens:
- iPad 1 iOS 5 : pink instead of video
- iPhone 4 iOS 7 : normal video
- iPhone 5 iOS 6 : pink
- iPhone 5S iOS 7 : normal

Looks like any device with iOS prior to 7 is not playing the videos correctly.

Could any one please confirm that they got the videos playing on iOS 6 or earlier using MMT 2.0.4?

 

Guess MMT is not supported anymore in this forum? Its a shame really.

 

I got a problem with playing movie on android.
The log says "Unable to find theorawrapper" Do I have to do something to work it out?

 

Yeah seriously. All they need to do is provide a little support and so many more would purchase their plugin.

 

I have been trying your plugins, and I was wondering if it is possible to have multiple plane with different video playing on them.

So I have a scene with 2 planes, and 1 GameObject with MMT component on it, both planes have the material Movie, same for the MMT, and the movie play on both planes. If i have a different material for each plane then I can play a video on a specific plane, but thats a weird way of doing things i think. Is there a way to specify which plane we want the movie to be played on?

 

I have been trying to put MMT and Kamcord into the same app and there seemed to have a conflict between the 2 plugins and was unable to compile in XCode... Anyone else had a similar problem and was able to find a way to resolve?

 

Hello,

I want to play video from my Android device SD Card with MMT. SO can you please guide me about how can i play video from SD card ?

Thank you.

 

Look at YCrCbtoRGBSplitAlpha .... YCrCbtoRGB....
uncomment from 1 to 62 line comment 66 to 315 line

and your problem be solved

 

Disabling DirectX 11 worked for me on windows (solved pink texture problem)

 

Our team is also seeing the same crash bug (Android only so far) as iTris666 and Adawat.SST. Is there any fix or workaround? It occurs more the more a player plays our game (and sees more movies)

Same stacktrace as them:

Hi everyone.

Playing a movie using the MMT, when to download and extract in the background,
Since the movie playback is slow, increasing the buffer for playback than to alleviate the symptoms, I believe.

Method of increasing the buffer for playback, or will there.

Thank you.

 

Wow. Thank you so much. It worked.
I only just saw your reply. For some reason, the forum stopped emailing me responses in this thread.
Is this somewhere in the docs or did you find it by experiment?
If it's not in the docs, it should be (and in a big font).

Just to be clear, I did these changes in the older version (1.1.7). The new version's shader doesn't have the commented out code. Although, now that I look at it, the new version looks extremely similar to the old commented part. I wonder why it isn't working.

Oh, well, the most important part is that at least one of the versions is now working.
Thanks again.

 

Hello,

I would like to buy the plugin but i have some issues with the demo version.
When i attach an alpha movie to the rgb movie same as the alpha demo in the plugin and then make it play with vuforia it workes fine. but when i want to play it from ipad i only see certain frames. the movie is terribly shocky.
i also can't play the movie in unity.

so when i dial down the resolution a lot then my movie appears as playable in unity. and it also worked at my ipad.
the only thing is that it is pixelated now.
is there a standard resolution for the alpha format? and is there a max resolution as well?

my other question is that i have put in a audio source and put in the mp3 file that belongs to the movie.
when i play this with vuforia on my ipad ( i have video looped) the first time it isn't synced but the second time it playes it is synced. is there something i can do with this?

is there a way i can sync sound from the start?

Im kinda at a dead end here and ive seen great result with this plugin so i know its doable.

Thanks in advance,

 

UPDATE: This bug has crept back up. Apparently my POT fix didn't really fix it and its happening again with latest Mobile Movie Texture update and QA testing. :-(

Solution to the crash described below!!! I never heard from the developers but after hours of testing we determined this was occurring only on our Samsung Galaxy S4 with Adreno GPU's and when playing non-square non-power of two sized movies. By converting all movies to 512x512 we no longer seem to see this error. Hopefully this works for everyone else!

 

I'm sorry if I repeat an already answered question but I've read the comment from gkazamias
( http://forum.unity3d.com/threads/mobile-movie-texture.115885/page-14#post-1691174 )
then the one from dukester
( http://forum.unity3d.com/threads/mobile-movie-texture.115885/page-15#post-1802123 )
and finally the one from borr
( http://forum.unity3d.com/threads/mobile-movie-texture.115885/page-15#post-1816485 )

Did I get this wrong or is it working with Unity Free 4.5 ?
Older comments and links seems to mention it is not possible, so I'm a bit confused! :/

 

I am trying out the MMT v2.0 on Unity 5.x and I am getting the OpenGLES error 0x0502 error.
How can I resolve this?

P.S. I am using an iOS device.

Kindly help!

 

I'm having trouble getting this to work in Linux. All I get is a black screen. Any ideas?

 

I'm having trouble getting the demo to work with Android. I tried Unity 4.6, then rolled back to 4.5.5f1. In-editor works, Android only shows green texture (also in the examples).
Is this problem restricted to the demo?

 

I am curious about the iOS/64Bit compatibility of the plugin.

As you might know apple has announced to only support 64 Bit compatible apps from february 2015 on.
http://blogs.unity3d.com/2014/11/20/apple-ios-64-bit-support-in-unity/

Will you guys support this ?

 

I have tested an X86 build on an ACER Iconia Tab 8. Which runs an X86 version of android.
This plugin will not work on the device. The apk will not even load to the Unity splash screen.
Can you offer any advice of a fix for X86?

 

I'm also trying to get this to work (Unity 4.5.5p1 and 4.6.1.f1 on a note4) and just getting a green screen (I also get a crash when either this or the OVR mobile sdk tries to access the gl context, but that's another issue)

I notice the plugin is setting up the android device as a GLES2.0 device. I've tried changing unity's settings to exclusively use that instead of GLES3.0, but no help there... There's a core_glTexSubImage2D:575: GL_INVALID_OPERATION trace which might suggest the demo app is trying to read/write to different texture formats...

 

For anyone struggling and need this kinda functionality (I can't find any plugins that work atm), I've started a unity c# script to decode a video with MediaExtractor/MediaCodec (using the Java bindings). It's not finished (got up to decoding), but can't work on this today...
Hope this helps someone (feel free to contribute changes)
https://github.com/SoylentGraham/UnityAndroidVideoTexture/blob/master/Assets/MediaCodec.cs

As for Dan (thread owner) I'm happy to delete this post if support comes back

 

Disabling Direct3D 11 solved the pink texture problem for me too,
*BUT*
it causes the whole Unity workspace to flicker and the content of windows in the workspace get really messed up. (On Windows 7)
Anyone else getting this? If Direct3D 11 is disabled, what does it use instead? Direct3D 9 or OpenGL or what?

Thanks

 

I'm getting the same issue. Can you please tell me which files you copied?
