More details.

Its creating a directory at C:\Users\philip\AppData\Local\Temp\javacpp105687008440412

It downloads these files

msvcp120.dll
msvcr120.dll
opencv_core300.dll
opencv_imgproc300.dll
jniopencv_core.dll

I think it fails on jniopencv_core.dll

The exception is thrown on this line

tempFile.deleteOnExit();

In file Loader.java

Getting an error trying to include ffmpeg

when I add this line to my build.sbt
javaCppPresetLibs ++= Seq("ffmpeg" -> "2.8.1")

not working on macos x

Added the addSbtPlugin("org.bytedeco" % "sbt-javacv" % "1.17")

Got

Caused by: java.lang.UnsatisfiedLinkError: no opencv_java343 in java.library.path

when calling

System.loadLibrary(Core.NATIVE_LIBRARY_NAME)

Automatically resolve latest version ?

An idea came up to look up the latest JavaCV version on Maven Central and use that as javaCVVersion. This is possible, but should be a bit better thought out to help with the following assumptions:

it assumes the ability to connect to Maven Central for the query
should probably have a fallback to a default version if querying fails
assumes that the user is ok with arbitrarily using the latest version, which can cause major compilation or runtime issues

update to 1.2

Please, update preset loading to 1.2 (it is 1.1 right now)

java.lang.UnsatisfiedLinkError: no jniopencv_videoio in java.library.path due to java.lang.UnsatisfiedLinkError: ... (libgtk-x11-2.0.so.0)

Hi,

I'm running scala (compiled using sbt) app that uses several OpenCV's functionalities. Eventually I managed to run some of them, but I still encounter the following exception:

Name: java.lang.NoClassDefFoundError
Message: Could not initialize class org.bytedeco.javacpp.opencv_objdetect$CascadeClassifier
StackTrace:

Notes:

My project/plugins.sbt file looks like this:

logLevel := Level.Warn
resolvers += Resolver.sonatypeRepo("releases")
addSbtPlugin("org.bytedeco" % "sbt-javacv" % "1.12")

My build.sbt looks like this:

name := "..."
version := "1.0"
scalaVersion := "2.11.8"
javaCppPresetLibs ++= Seq("opencv" -> "3.1.0", "ffmpeg" -> "3.1.2")
javaCppPlatform := Seq("linux-x86_64")

I'm coding+debugging on Windows machine where everything runs smoothly. Then I tried adding the linux-x86_64 platform to the build.sbt as in (2) and use sbt-assembly to package my linux-ready jar. I uploaded that jar into my linux cluster, then cloned the 3.1.0 version of opencv from https://github.com/Itseez/opencv and ran cmake, make and make install.
Finally, in scala, this piece of code works great (uses org.bytedeco.javacpp.opencv_imgcodecs & org.bytedeco.javacpp.opencv_imgproc):

import org.bytedeco.javacpp.BytePointer
import org.bytedeco.javacpp.opencv_core.{Mat, _}
import org.bytedeco.javacpp.opencv_imgcodecs._
import org.bytedeco.javacpp.opencv_imgproc._
import org.bytedeco.javacpp.opencv_objdetect.CascadeClassifier
 
val bytes = ByteBuffer.wrap( /* some Byte array */ )
val imgCvMat = cvDecodeImageM(cvMat(1, bytes .array().length, CV_8UC1, new BytePointer(bytes )))
val imgMat = cvarrToMat(imgCvMat)

while this code:

val faceCascade = new org.bytedeco.javacpp.opencv_objdetect.CascadeClassifier( /* path to xml of classifier configuration */ )

fails with the following exception:
