Hello!
I'm trying to build an app for android with GUI written on Qt. Now I'm working on video preview. What i've done already:
1. Build OpenH264 lib.
2. Build pjsip with video support.
3. Copy PjCamera.java and PjCameraInfo.java into my app folder (src\org\pjsip\).
The problem is that pjsip unable to find class name PjCamera from JVM. I have this debug log:
.............
I/pjsua (16412): 22:52:38.159 android_jni_de ..Android JNI sound library initialized
I/pjsua (16412): 22:52:38.162 pjlib ..select() I/O Queue created (0xb861b48c)

I/pjsua (16412): 22:52:38.184 android_dev.c ...[JNI] Unable to find class 'PjCamera'
.............
And when I'm trying to create preview video program crashes. (I'm not sure that I'm creating video preview with correct device and maybe this is another error).
My code:
vidPrev = new VideoPreview(PJMEDIA_VID_DEFAULT_RENDER_DEV);
VideoPreviewOpParam param;
vidPrev->start(param); // <-- crash here
VideoWindow prev = vidPrev->getVideoWindow();
Crash log:
I/pjsua (16412): 22:52:39.511 pjsua_vid.c !Starting preview for cap_dev=-2, show=1

Does anybody faced with such error before?
