• Problem with Linking FFMPEG Libraries in Visual Studio on Windows 10 [closed]

  14 mars 2024, par Dentricky73

  I'm facing an issue while trying to link FFMPEG libraries in Visual Studio on a Windows 10 OS. Specifically, Visual Studio seems to locate the headers correctly, but encounters difficulties in finding the associated libraries. Initially, I attempted to compile the FFMPEG SDK myself, but encountered problems with the library extensions, which ended with a Linux .o file instead of a Windows .lib. Subsequently, I downloaded a prebuilt version from here, but I'm still encountering errors.

  


  In Visual Studio 2022, I've configured the following settings :

  


  


  Property > Configuration Properties > C/C++ > General > Additional Include Directories
C :\cmder\c++SDK\ffmpeg\include

  


  


  


  Property > Configuration Properties > Linker > General > Additional Library Directories
C :\cmder\c++SDK\ffmpeg\lib

  


  


  


  Property > Configuration Properties > Linker > Input > Additional Dependencies
avcodec.lib, avdevice.lib, avfilter.lib, avformat.lib, avutil.lib, postproc.lib, swresample.lib, swscale.lib

  


  


  Despite these configurations, Visual Studio fails to locate the FFMPEG libraries during the linking process. Could someone please provide guidance on how to resolve this issue and correctly link the FFMPEG libraries in Visual Studio on Windows ? Any help or insights would be greatly appreciated.

  


  Specific Issues Encountered :

  


  During the compilation and linking process in Visual Studio 2022, I encountered the following errors :

  


  Error 1 : A value of type "const AVCodec *" cannot be used to initialize an entity of type "AVCodec *".
Error 2 : Identifier "av_free_packet" is undefined.
Error 3 : Class "AVStream" has no member "codec".
Error 4 : Class "AVFrame" has no member "owner".
Despite configuring the project settings to include the correct include directories and library dependencies, these errors persist.

  


  Why Previous Attempts Didn't Meet My Needs :

  


  My previous attempts to resolve these issues were unsuccessful because I couldn't pinpoint the root cause of the compilation and linking errors. While I ensured that the include directories and library dependencies were correctly configured in Visual Studio, the errors persisted, indicating that there may be underlying issues with the setup or compatibility between the FFMPEG SDK and Visual Studio environment.

  


• Using ffmpeg to convert video audio and thumbnail in separate threads ?

  26 janvier 2018, par Oleksandr Kyrpa

  I converting lot of videos and same time ago, I found what if split converting process to different task then I can speed up total process. Because, for example, ffmpeg process don’t need wait for processing raw data to video decoder if audio frame was readed from input file, just skip this frame.

  process1 for video

  ffmpeg -i video.mp4 -an -c:v h264 ..... -y out.h264

  process2 for audio

  ffmpeg -i video.mp4 -vn -c:a aac ...... -y out.aac

  process3 for thumbnail

  ffmpeg -i video.mp4 -vf fps=1/60 img%03d.jpg

  And after all process was completed then I need to marge video and audio tracks in to mp4 container. Using this method I solve bottle neck problem and got seed up total process.

  ffmpeg -i out.h264 -i out.aac -c:v copy -c:a copy -y out.mp4

  But any other way to speed up convertion in modern ffmpeg ?
