HI, all
This is my first post here 
I’d like some help please regarding the Easy movie Texture.
I am trying to play either a local file from streamingassets of on mp4 file in a server and in both cases in the android get a black screen with only sound.
in the pc version i have no problem i get voth audio and video.
any one that can help me here please ?
If you use Unity 5.6 you could use the Video Player API instead of Easy Movie Texture.
Though regarding Easy Movie Texture, it’s a plugin made by a korean guy. You might want to contact the plugin owner for this case 
Easy Movie Texture doesn’t load video’s from streaming assets, it downloads it from the streaming assets using WWW class and just puts it into the Application.PersistentDatapath folder and then loads it. Now there’s a huge memory footprint when using WWW because it loads the downloaded bytes in memory, then writes it to the disk.
Another case is that your video might not be supported on the Android platform. It has to be decoded natively on android which it may not be possible due to having a wrong profile. which means it should be encoded with a profile that is compatible on Android.
The video file resolution is probably bigger than your Android device supports. Each android device supports different max res videos, so you’ll need to check max resolution for your device.
How does one go about contacting this Korean lad?
I got the same issue. I included several .mp4 less than 4mb videos inside the StreamingAssets folder to play them consecutively one after the other, and for some reason when I build the .apk and play it in my phone, it only plays the first 5 videos and after that a Black Screen. I am a newbie, so I ask… why does this happen? Is it because there is a limit of videos to load in the StreamingAssets folder? Is it a limitation of the asset itself? Please help!
I have just solved my black video screen issue with an Easy Movie Texture setup.
Problem:
The file extension of my movie asset was .MP4 ,
I was typing .mp4 for the file path in the MediaPlayerCtrl.cs variable in the inspector
First I was getting the black screen (there was no audio in these movie files so I don’t know if there was any sound or not). To fix this I deleted the ‘Dummy’ texture that was assigned to the Video Material that is assigned by default.
This however, caused my black screen to become a white screen - still no video.
After much cross-referencing with another project that already had some Easy Movie Texture videos working in it, I found that the movie files in the failing project had the extension .MP4, while I was writing .mp4 in the MediaPlayerCtrl.cs - Str File Name variable in the inspector.
After updating my project in the Google Developer Console, waiting…then testing…videos are alive! Happy Days! Project complete!
(I don’t know what part the deleting of the Dummy.sprite had to play, if any. When I play the project in the editor this empty texture slot gets filled with the movie anyway.)
@cdunne1 You probably already figured this out by now…All plugin authors give their contact details in the Unity Asset store:
