Crashes about glwallpapervideodemo HOT 10 CLOSED

Sounds like eclipse isn't finding the compiled JNI code (.so library files). I originally didn't use Eclipse for that project.

You should have a LIBS folder with at least one subfolder ARMABI and possibly also ARMEABI-V7A. You should see the precompiled .so files in there. That's how I set up the git repo. If not then you'll have to drop down to the command line and compile the JNI code.

If the files are there and it still doesn't work, try adding an Application.mk file to the JNI folder containing this:

APP_ABI := armeabi

Refresh the Eclipse project and compile.

--Thanks!

Hi, I have followed the instructions on your website and recompiled everything which at first removed the problems and now logcat gives me the following problems:

Yeah, you're gonna have to drop to the command line and compile the JNI code.

The package name is hardcoded in the JNI code. So open video.c and update every function call with your package name. Make sure to follow the JNI style. So for example,

Java_ffvideolivewallpaper_frankandrobot_com_NativeCalls_initVideo

becomes

Java_com_danielcotton_tabletlpw_NativeCalls_initVideo

Then recompile:

ndk-build clean
ndk-build

If it still doesn't work, you may also have to recompile FFMPEG. Take a look at README-COMPILE-FFMPEG. Of particular importance is the --soname-prefix flag in build.sh. It's also hardcoded with the package name. Update this flag with your package name and run build.sh to compile FFMPEG.

Thankyou very much! That fixed the issue

from glwallpapervideodemo.

i also just realized that a quicker way is to compile my project as a library then include it in your project. everything works auto magically. you just override my wall paper class.

Sorry, a couple more questions, are Quicktime files compatable and does it have Alpha support

Thanks

from glwallpapervideodemo.

if ffmpeg supporta it then yes. i believe so. check the list of supported codecs when you run .configure in the ffmpeg folder. not sure what alpha is.

Alpha as in transparency, ie the frames compressed as .png within a quicktime codec

Hi
Frankandrobot

Thank you very much for sharing your code FFvideoLiveWallpaper. I want to rename application package name. I have followed the instructions on your website and recompiled everything. I have updated every function call in video.c with my package name to follow the JNI style and clean the ndk-build and then recompile. But still I am not able to call Native Method and my application crashes. Log cat gives me the following problems:

java.lang.UnsatisfiedLinkError: initVideo at
com.danielcotton.tabletlwp.NativeCalls.initVideo(Native Method).
And I want to span the video on whole screens but video is spanning only on two or three screens. Please tell me how to span the video on whole screens.
I’ll be really thankful, if you would help me in this.

Thanks and regards
Vinay
