Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Combining JavaCV and openCV
13 juin 2014, par mister-viperI have the following problem :
I have an Android application which uses native OpenCV code. In a first step, the frames which were edited by OpenCV came from the camera. Then they were processed and drawn on the display.However, my requirements now have changed. The frames which have to be edited come from a video file stored on the SD card. They must be processed by the openCV code and then stored in a new video file.
After reading some a lot of stuff, I recognized that Android has no built-in stuff for correctly reading a video file frame by frame and allowing to process the frames while doing so. On a computer OpenCV has the VideoCapture function. But this does not work on Android as openCV has no ffmpeg that comes with it.
After reading more stuff, I found that JavaCV comes with an FFMPEGFrameGrabber and also an FFMPEGFrameRecorder. So, I implemented everything which now allows me to grab single frames from a video, obtain an IplImage frame and store this frame in a new video.
Now the problem :
During obtaining and storing the IplImage frame must be processed using the original OpenCV code as it is not feasible to port the complete code to JavaCV.So in a first place I wrote a small test JNI function which gets the address of a MAT object and draws a small circle on it.
extern "C" {
JNIEXPORT void JNICALL Java_de_vion_postprocessing_step2_EyeTracking_editFrame(
JNIEnv*, jobject, jlong thiz, jlong addrRgba) {
//Convert the mat addresses into the objects
Mat& rgbFrame = *(Mat*) addrRgba;
Point2i scaledSmoothPoint(100,100);
circle(rgbFrame, scaledSmoothPoint, 20, YELLOW, -1);
}As I read that IplImage extends CvArr I just call the function within in my code as follows :
captured_frame = grabber.grab();
if (captured_frame == null) {
// no new frames
break;
}
editFrame(captured_frame .address());However, I now get the following error :
06-12 18:58:23.135: E/cv::error()(6498): OpenCV Error: Assertion failed (cn <= 4) in
void cv::scalarToRawData(const Scalar&, void*, int, int), file
/home/reports/ci/slave_desktop/50-SDK/opencv/modules/core/src/matrix.cpp, line 845
06-12 18:58:23.135: A/libc(6498): Fatal signal 6 (SIGABRT) at 0x00001962 (code=-6),
thread 6526 (AsyncTask #1)Finally, me question :
How can I process the IplImage frame using nativeOpenCV and finally store this IplImage frame then in the video recorder.I am also open to new Ideas which do not necessarily require JavaCV as long as I do not have to write the FrameGrabber and FrameRecorder my self.
Best regards,
