#StackBounty: #android #opencv #jni #opencv4android Error while loading YAML model file using opencv in android

Bounty: 50

I am using opencv for facial landmark detection in android. I am using JNI for interaction with library. I have saved “lbfmodel.yaml” file in assets and trying to load :

const char* jnamestr2 = jenv->GetStringUTFChars(jModelFileName, NULL);
cv::String stdFileName2(jnamestr2);
LOGD( "jModelFileName path : %s", jnamestr2);
FacemarkLBF::Params params;
params.model_filename = stdFileName2;
params.cascade_face = stdFileName;
Ptr<FacemarkLBF> facemark = FacemarkLBF::create(params);

But I am receiving error :

Invalid address 0x9b2d2e08 passed to free: value not allocated
Fatal signal 6 (SIGABRT), code -6 in tid 27673

I have logged the filepath and it is :

jModelFileName path : /data/user/0/com.ds.openworld/app_model/lbfmodel.yaml

I don’t know what is the issue because it is crashing in native part. The model file is also large. Is that an issue?

Please help!
