I’ve successfully compiled opencv statically on a PiZero. And I am not able to read a h264 video file while I can read it with a standard compilation (with shared libraries).
I join my code here. I have no error at the compilation step. But when I run it, I am not able to have a cap.isOpened() == true…
Do you have an idea of what am I doing wrong?
Here is a code:
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main(int argc, char* argv[])
{
//open the video file for reading
VideoCapture cap("/home/pi/toto.h264");
// if not success, exit program
if (cap.isOpened() == false)
{
cout << "Cannot open the video file" << endl;
cin.get(); //wait for any key press
return -1;
}
//Uncomment the following line if you want to start the video in the middle
//cap.set(CAP_PROP_POS_MSEC, 300);
//get the frames rate of the video
double fps = cap.get(CAP_PROP_FPS);
cout << "Frames per seconds : " << fps << endl;
return 0;
Thanks a lot for your answer. I paste the output of my cmake here (I didn’t find the option to attach a file to my reply…)

I am a bit dumb…

Cannot open the video file
are you sure, that was on the same machine ? your cmake log is showing, that no gstreamer components are installed, and that ffmpeg is missing dependancies. you need to fix one or the other, regardless of static/dynamic linking
OK @crackwitz, I saw the avresample line in the log.
After: sudo apt-get install libavresample-dev
I’ve got a YES at the end of the line of “avresample” in the log, but I still have a NO on FFMPEG.
I try to find a way to install libmmal_core in a static way (libmmal_core.a) but I only have the .so one and I am not able to find a way to install the .a file …
Thanks for your answer @Supra. I am not sure to understand your point on python nd virtualenvs…
On my side I don’t need python bindings. I want to use it with C++.
On installing FFMPEG, I am trying to install it on my PiZero…
The system tells me that it is already installed…
But I have already the .so version of libmmal_core. I am looking for the static version (libmmal_core.a)…
what’s the output of the cmake configure step now that you got that avresample issue fixed? what’s the exact command you use to run cmake (all command line arguments)?
I think…
In a previous cmake I had a missing avresample. And after installing this lib with sudo apt, now I can see the YES for avresample. So I think the cmake is good…
Here is the cmake command I use: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_SHARED_LIBS=OFF -D OPENCV_EXTRA_MODULES_PATH=$(TMP_DIR)opencv/opencv_contrib-$(OPENCV_VERSION)/modules -D BUILD_DOCS=OFF -D BUILD_EXAMPLES=OFF -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_opencv_java=OFF -D BUILD_opencv_python=NO -D BUILD_opencv_python2=NO -D BUILD_opencv_python3=NO -D ENABLE_VFPV2=ON -D WITH_JASPER=OFF -D OPENCV_GENERATE_PKGCONFIG=ON ..
