• Can't link FFMPEG dynamically to VS 2019 project

  10 février 2021, par Maya Sela

  I downloaded the source code of FFMPEG 3.4.8 and built with MSVC as such :
  
After unzipping, open x86_x64 Cross Tools Command Prompt for VS 2019 and run msys2_shell.cmd. From there, run
  
./configure --toolchain=msvc --arch=x86_64 --enable-yasm --enable-asm --enable-shared --disable-static
and
make

  
I then created a new project in VS 2019.
  
In Properties > C/C++ > General > Additional Include Directories :
  
(Where all the headers are)

  


  E:\ffmpeg-3.4.8\libavutil
E:\ffmpeg-3.4.8\libavcodec
E:\ffmpeg-3.4.8\libavdevice
E:\ffmpeg-3.4.8\libavfilter
E:\ffmpeg-3.4.8\libavresample
E:\ffmpeg-3.4.8\libpostproc
E:\ffmpeg-3.4.8\libswscale
E:\ffmpeg-3.4.8\libswresample
E:\ffmpeg-3.4.8\libavformat


  


  In Properties > Linker > General > Additional Library Directories :
  
(Where the .lib files are)

  


  E:\ffmpeg-3.4.8\libavutil
E:\ffmpeg-3.4.8\libavcodec
E:\ffmpeg-3.4.8\libavdevice
E:\ffmpeg-3.4.8\libavfilter
E:\ffmpeg-3.4.8\libavresample
E:\ffmpeg-3.4.8\libpostproc
E:\ffmpeg-3.4.8\libswscale
E:\ffmpeg-3.4.8\libswresample
E:\ffmpeg-3.4.8\libavformat


  


  In Properties > Linker > Input > Additional Dependencies :

  


  avcodec.lib
avdevice.lib
avfilter.lib
avformat.lib
swresample.lib
swscale.lib


  


  For good measure, I copied the .dll files of each library to the Release folder of the project. There is one source file I am trying to build and run :

  


  &#xA;extern "C" {&#xA;#include <libavformat></libavformat>avformat.h>&#xA;}&#xA;&#xA;int main() {&#xA;    AVFormatContext* pFormatContext = avformat_alloc_context();&#xA;}&#xA;

  


  The result is as follows :

  


  1>------ Build started: Project: FFMPEG_example, Configuration: Release x64 ------
1>Source.cpp
1>Source.obj : error LNK2001: unresolved external symbol avformat_alloc_context
1>C:\Users\maya.s\source\repos\FFMPEG_example\x64\Release\FFMPEG_example.exe : fatal error LNK1120: 1 unresolved externals
1>Done building project "FFMPEG_example.vcxproj" -- FAILED.
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========


  


  Does anyone have an idea ?
  
Thanks !

  


• The Mystery of the No such file or directory exception

  22 avril 2022, par JohnWick

  No idea what's going on here. Set a breakpoint after the for of loop in the following function. temp/concat.txt exists but the following exception is thrown :

  


  


  Uncaught Error Error : ffmpeg exited with code 1 : temp/concat.txt : No
such file or directory

  


  


  Outputting stderr gives a bit more info :

  


  


  [concat @ 000001e2e30124c0] Impossible to open
'temp/concat.txt#voiceover #funny #fall #lol.mp4' index.js:19

  The function throwing the exception.

  


  async function makeCompilation(paths, outPath) {

• I want to reduce my PYTHON code and also make proper

  7 mai 2022, par Anuj Saxena

  I have a CSV file From the client.
In my code, first, read the CSV file and create folders based on the CSV Column Heading name
and, convert the video into jpeg and also compress the video and apply a watermark on the compressed video.
hi below is my code example. Is there a way to reduce the number of lines of code and save time ?
example.. using function or loops. I need any other method. please help

  


  

  


  CODE BEGIN
