Android arm7 libavutil.so "not found"

[GoogleCodeExporter]

Andoid doesn´t want to load the arm7 version of libavutil.so :-(

What steps will reproduce the problem?
1. Copy the ffmpeg and opencv libs into /libs
2. Use FFMpegFrameGrabber
3. "Couldn't load jniavutil: findLibrary returned null"

What is the expected output? What do you see instead?
It should load the EXISTING file libavutil.so.
If I remove the armeabi-v7a folder, it works completely.

What version of the product are you using? On what operating system?
android 3.2 (Dell Streak 7)

Please provide any additional information below.

Oh, I´m blind..
Of course it´s "libjniavutil.so" that couldn´t be found.
But where can I get that from?
The armeabi-version doesn´t work as armeabi-v7a.

Are you saying that this app does not run on your device?

This .apk doesn`t use native ffmpeg.
I`ll test it later

It does work.
But I/Android have/has problems finding libjniavutil.so for arm7 :-(

Then it works. You don't need a different libjniavutil.so. If you follow the 
instructions in the README.txt file, and basically you did, because as you said 
"If I remove the armeabi-v7a folder, it works completely." so, there is no 
problem.

But I want to use the arm7-libs, because they should be much faster in decoding 
videos!

Yes, you can use those. Just follow the instructions in the README.txt file and 
put them in "libs/armeabi".

But then a non-arm7-device won´t work.
