Javacpp-presets: FFmpeg build failure on Jetson tx2 (linux-arm64)

[chichunchen]

I'm trying to decode video on Jetson tx2 and I followed the tutorial in the paragraph of Native Compilation. The compilation for FFmpeg seems good, but after the compilation I got failure message on patching. Below is the log on TX2:

The actual command I typed to compile is:

$ sudo apt-get update
$ sudo apt-get install clang ant maven python swig git file wget unzip tar bzip2 gzip patch autoconf-archive automake make cmake libtool perl nasm yasm gfortran libasound2-dev freeglut3-dev libgtk2.0-dev libusb-dev zlib1g
$ git clone https://github.com/bytedeco/javacpp-presets.git
$ cd javacpp-presets
$ mvn install -Djavacpp.platform=linux-arm64 -Dmaven.javadoc.skip=true

which only change the platform in the last line from armfh to arm64.

@mjhas @Spawn32 ideas?

[mjhas]

well the patch which is not sucessfully applied was written for VPX 1.6.1 - now the version is VPX 1.7.0. Either adapt the patch to work with 1.7.0 or remove/disable it entirely.

[saudet]

@mjhas Yeah, I see... Could you update it? :)

[yuhao]

Hi! Could we get some guidance in terms of how to disable this patch or adapt it?

[saudet]

I've updated the patch, please try again.

[chichunchen]

Thanks a lot! I'm now able to compile ffmpeg in javacpp-preset. However, by using the javacv installed via maven, the binary seems to be yet updated. It still give me the NoClassDefFoundError like this:

Exception in thread "Thread-0" java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.javacpp.avutil
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Class.java:348)

    at org.bytedeco.javacv.FFmpegFrameGrabber.<clinit>(FFmpegFrameGrabber.java:296)
    at VRPlayer$SVRNetworkHandler.run(VRPlayer.java:222)

Therefore, I decide to compile the whole tool chain manually (javacpp-preset, javacpp, and javacv), but while compiling javacpp, it gives me fail message:

I actually only need ffmpeg on my tx2, but to compile javacv manually, I seems to have to compile all the module in javacpp-preset, or can I just use the jar file of ffmpeg and opencv to compile javacv?

[saudet]

If you only use FFmpeg, you don't need the rest, no. Please set the "org.bytedeco.javacpp.logger.debug" system property to "true" and let's see what it's trying to load. BTW, you need to make sure ffmpeg-linux-arm64.jar file is in your class path.

[saudet]

BTW, it would be nice to have builds for linux-arm64. If anyone would like to contribute, please go to https://github.com/bytedeco/javacv/issues/1021 for some additional information, thanks!
