Not able to link ffmpeg library in cython package
12 août 2020, par Sagar DonadkarI am using cython package to call Cpp API and in my cpp code i am using ffmpeg library when i try to build my code i got and linking issue
In header file add include ffmpeg header file to call ffmpeg library function


header file
#ifndef RECTANGLE_H
#define RECTANGLE_H
#include <iostream>

extern "C"
{
 #include "libavformat/avformat.h"
 #include "libavutil/dict.h"
}

using namespace std;

namespace shapes 
{
 class Rectangle {
 public:
 int x0, y0, x1, y1;
 Rectangle();
 Rectangle(int x0, int y0, int x1, int y1);
 ~Rectangle();
 int getArea();
 int ffmpegFile();
 void getSize(int* width, int* height);
 void move(int dx, int dy);
 };
}

#endif
</iostream>

Rectangle.Cpp file in ffmpegFile() i am using ffmpeg example code to test ffmpeg my code where i call mostly ffmpeg API



#include <iostream>
#include "Rectangle.hpp"

namespace shapes {
 

 // Default constructor
 Rectangle::Rectangle () {}

 // Overloaded constructor
 Rectangle::Rectangle (int x0, int y0, int x1, int y1) {
 this->x0 = x0;
 this->y0 = y0;
 this->x1 = x1;
 this->y1 = y1;
 }

 // Destructor
 Rectangle::~Rectangle () {}

 // Return the area of the rectangle
 int Rectangle::getArea () {
 return 10;
 }

 // Get the size of the rectangle.
 // Put the size in the pointer args
 void Rectangle::getSize (int *width, int *height) {
 (*width) = x1 - x0;
 (*height) = y1 - y0;
 }

 // Move the rectangle by dx dy
 void Rectangle::move (int dx, int dy) {
 this->x0 += dx;
 this->y0 += dy;
 this->x1 += dx;
 this->y1 += dy;
 }
 int Rectangle::ffmpegFile()
 {
 AVFormatContext *fmt_ctx = NULL;
 AVDictionaryEntry *tag = NULL;
 int ret = 0;
 char* filename = "D:\\Discovery.mp4";

 if ((ret = avformat_open_input(&fmt_ctx, filename, NULL, NULL)))
 return ret;

 if ((ret = avformat_find_stream_info(fmt_ctx, NULL)) < 0) {
 av_log(NULL, AV_LOG_ERROR, "Cannot find stream information\n");
 return ret;
 }

 while ((tag = av_dict_get(fmt_ctx->metadata, "", tag, AV_DICT_IGNORE_SUFFIX)))
 printf("%s=%s\n", tag->key, tag->value);

 avformat_close_input(&fmt_ctx);
 return ret;
 }
}
</iostream>

Rectangle.pxd file declaration for cpp file function and variable


cdef extern from "Rectangle.cpp":
 pass
cdef extern from "Rectangle.hpp" namespace "shapes":
 cdef cppclass Rectangle:
 Rectangle() except +
 Rectangle(int, int, int, int) except +
 int x0, y0, x1, y1
 int getArea()
 void getSize(int* width, int* height)
 void move(int, int)
 int ffmpegFile()


rect.pyx file i am calling cpp API form pyx file


# distutils: language = c++

from Rectangle cimport Rectangle

cdef class PyRectangle:
 cdef Rectangle c_rect # Hold a C++ instance which we're wrapping

 def __cinit__(self, int x0, int y0, int x1, int y1):
 self.c_rect = Rectangle(x0, y0, x1, y1)

 def get_area(self):
 return self.c_rect.getArea()

 def get_size(self):
 cdef int width, height
 self.c_rect.getSize(&width, &height)
 return width, height

 def move(self):
 print(self.c_rect.ffmpegFile())


setup.py
I provided pyx file and ffmpeg library path as well as include path


from setuptools import setup,Extension
from Cython.Build import cythonize 


directives={'linetrace':False, 'language_level':3}

setup(name = 'superfastcode', version = '1.0',
 description = 'Python Package with superfastcode C++ extension',
 ext_modules=cythonize([
 Extension(
 'demo',["rect.pyx"],
 include_dirs=['ffmpeg\\include'],)
 library_dirs=["ffmpeg\\lib"],
 libraries=["avcodec","avformat","avutil","swscale","avdevice","avfilter","postproc","swresample"]),

getting below error

avcodec/msrledec : implement vertical offset in 4-bit RLE
29 novembre 2016, par Daniel Verkampavcodec/msrledec : implement vertical offset in 4-bit RLE
The delta escape (2) is supposed to work the same in 4-bit RLE as in
8-bit RLE. This is documented in the MSDN Bitmap Compression page :
https://msdn.microsoft.com/en-us/library/windows/desktop/dd183383(v=vs.85).aspxThe unchecked modification of line is safe, since the loop condition
(line >= 0) will check it before any pixel data is written.Fixes ticket #5153 (output now matches ImageMagick for the provided sample).

Installing gifify on Windows
23 février 2016, par Robert WojciechowskiSo gifify is a pretty awesome script that converts videos to gifs via command line : https://github.com/vvo/gifify
I’m keen to get this working on my Windows 10 machine. I’m pretty new to windows and relatively new to coding, but I was able to get a few things working, but ran into a problem.
Here is what I did :
- Installed node.js + npm
- Installed FFmpeg using npm
- Installed ImageMagick using npm (i think i did this wrong, might have only installed the wrapper).
- Downloaded giflossy. It needed to be built (?)
- Installed Visual Studio 2015, tried to build it using nmake and got this error :
NMAKE : fatal error U1073: don't know how to make 'win32cfg.h'The command I used was :
PS C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin> .\nmake -f "C:\Users\Robert's Workstation\.npm-global\node_modules\giflossy-lossy-1.82.1\src\Makefile.w32"Would really appreciate some help with this :D
