Please try to follow the instructions here:

[a610569731]

Ask how to solve

[saudet]

Following the installation instructions should solve this issue. If they do not, then please provide more information about your device, etc.

I need your help on the line app

[saudet]

Maybe it has something to do with ProGuard:
https://github.com/bytedeco/javacv/wiki/Configuring-Proguard-for-JavaCV

[a610569731]

[saudet]

So you need ARM 64-bit binaries? Could you provide the necessary changes for that? It would help a lot, thanks!

[saudet]

You're going to need to modify and run cppbuild.sh too:
https://github.com/bytedeco/javacpp-presets#cppbuild-scripts
And also add a new android-arm64 or something platform to JavaCPP:
https://github.com/bytedeco/javacpp/tree/master/src/main/resources/org/bytedeco/javacpp/properties

[saudet]

Could you try again with version 1.0 and let me know if you get the same error? Thanks!

[arvind-das]

Hi Saudet, I am getting the same error. I am on version 1.0

@arvind-das see issue #37

[arvind-das]

Thanks but no success here, looks like I need to spend more time one this as this seems to be the issue with most people. Will not make hurry now. After setting up, presets and installing opencv correctly , on building javacv, getting this error:

[ERROR] Failed to execute goal on project javacv: Could not resolve dependencies for project org.bytedeco:javacv:jar:1.0: The following artifacts could not be resolved: org.bytedeco.javacpp-presets:ffmpeg:jar:linux-arm:2.7.1-1.0, org.bytedeco.javacpp-presets:flycapture:jar:linux-arm:2.7.3.19-1.0, org.bytedeco.javacpp-presets:libdc1394:jar:linux-arm:2.2.3-1.0, org.bytedeco.javacpp-presets:libfreenect:jar:linux-arm:0.5.2-1.0, org.bytedeco.javacpp-presets:videoinput:jar:linux-arm:0.200-1.0, org.bytedeco.javacpp-presets:artoolkitplus:jar:linux-arm:2.3.1-1.0, org.bytedeco.javacpp-presets:opencv:jar:linux-arm:3.0.0-1.0, org.bytedeco.javacpp-presets:flandmark:jar:linux-arm:1.07-1.0: Failure to find org.bytedeco.javacpp-presets:ffmpeg:jar:linux-arm:2.7.1-1.0 in http://repo.maven.apache.org/maven2

Also, please let me know which jar should have org.bytedeco.javacpp.avutil class.!

[arvind-das]

Hi @saudet , I successfully installed javacpp-presets. OpenCV-3.0.0 and javacv 1.0. The newly generated ffmpeg and other packages on the raspberry pi now contains above missing class "org.bytedeco.javacpp.avutil" . Here is the link to all those generated files residing in my pi's local mvn folder .m2 .
link to files!

But javacv 1.0 is still not building saying the above error that it could not find dependencies .

Please note: my raspberry pi is running ubuntu 14.04. I will post out a complete blog on this to make sure things work with others too but I need to run my first. :)
Cheers!

[saudet]

There's still no file named ffmpeg-2.7.1-1.0-linux-arm.jar! You need a file named ffmpeg-2.7.1-1.0-linux-arm.jar.

[arvind-das]

Okay, but isn't it that, required class files should be present in the jars for supporting execution. So what I did is, copied >ffmpeg-2.7.1-1.0.jar to >ffmpeg-2.7.1-1.0-linux-arm.jar which makes it present there and javacv build on pi is a success , but the problem remains same,

java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.javacpp.avutil

Please help me out!

[saudet]

@arvind-das No that's not going to work. Like I said, see issue #37.

[arvind-das]

@saudet Okay, but that is not helping either, I am not sure why these files are not getting generated even if everything compiled correctly. Looks like its time to Yoga, take a fresh breathe and come back for me. :)

[saudet]

@arvind-das Ok, so what do your modifications to the cppbuild.sh file look like?

[saudet]

That's for OpenCV. You're trying to use FFmpeg. You need to do the same for FFmpeg's cppbuild.sh script file.

[arvind-das]

Oops! my bad, will do that right away, I thought I just need to fix with opencv , platform for rest will be detected automatically.

[saudet]

If anyone would like to work on binaries for the android-arm64 platform, please let me know! Thank you

[arvind-das]

I am gaining some speed with installing cross tool compiler, no success yet but I can see the sun. Will update once my installation is done.

[pradeep2929]

I am getting crash in Android 5.1, Native platform armeabi-v7a, CPU model MSM8916. The model suggests it should support 32 bit .so files. But it crashes. I downloaded the most recent javacpp release, it has armeabi support only. Is there a release package available for download for 64bit chips?

@saudet sorry but how can I fixed the issue:

"xxx" is 32-bit instead of 64-bit

Tried to find the solution but got nothing. Could you please help me?

[saudet]

@viettanbkdn It looks like for some reason you need 64-bit binaries. There isn't currently a build for that. Someone needs to work on that. If you could help with doing that, it would be great! Contributions are welcome.

[nickbernz]

Salut,

As per today, what is the status with ffmpeg and arm64. I definitly needs them and how could I help?

merci

[saudet]

@nickbernz Help is welcome!

[rubi-sharma]

I need help to build .so files for android-arm64.

[saudet]

64-bit builds for Android (as the "android-arm64" and "android-x86_64" platforms) are now available, so please give it a try! Binaries for 1.4.1-SNAPSHOT can be downloaded from the snapshot repository: http://bytedeco.org/builds/

[saudet]

Artifacts have now been released as version 1.4.1. Enjoy and thanks for your patience!

[girishnr1]

I have downloaded all the .jar files and configured Eclipse project to uses DL4J.
I'm getting below exception when loading previously saved model. Please help.

Code snippet:
String simpleMlp = new ClassPathResource("mymodel.h5").getFile().getPath();

[saudet]

@girishnr1 HDF5 isn't supported on Android.

[girishnr1]

The error is on windows machine ( windows 7).
DL4J is setup using instructions under:
https://deeplearning4j.org/docs/latest/deeplearning4j-quickstart
I see that javacpp-1.3.1.jar, Is there an updated version that supports hdf5?

[saudet]

@girishnr1 Please upgrade to the latest version, and if you're still having problems, please ask on the support channels of Deeplearning4j, not here.
