• Error while linking shared library FFMpegJNI to android project

  5 mars 2024, par Dari V

  I have built an ffmpeg module for all the architectures, but when I try to build project to run it on emulator (x86 architecture) i get an error, indicating that the files for x86 architecture are incompatible with elf_i386. The same is for other architectures, i get the error that the files are incompatible. What can i do in this case ?

• Output file does not show up after executing ffmpeg command [closed]

  19 février 2024, par davai

  I'm using ffmpeg to combine an MP3 + G file and produce an MP4 file. I've placed the source code / .exe file for 'ffmpeg' in the project folder, and the MP3 + G files are also in the project folder. I also set the MP4 output to show up in the project folder as well. The weird thing is that, initially, I was producing output files, and while trying to tweak the constant rate factor, the MP4 output just stopped showing up entirely. I'm also not receiving any errors while running the code, and it does print out that the file has been successfully created, despite nothing showing up in the project folder.

  


  
        String mp3FilePath = "C:/Users/exampleuser/pfolder/example.mp3";
        String gFilePath = "C:/Users/exampleuser/pfolder/example.cdg";
        String mp4OutputPath = "C:/Users/exampleuser/pfolder/example.mp4";

        try
        {
            String[] command = {
                    "C:/Users/tonih/IdeaProjects/MP3GtoMP4Conversion/ffmpeg/ffmpeg-2024-02-19-git-0c8e64e268-full_build/bin/ffmpeg.exe",
                    "-i", mp3FilePath,       // Input MP3 file
                    "-r", "25",              // Frame rate
                    "-loop", "1",            // Loop input video
                    "-i", gFilePath,         // Input G file
                    "-c:v", "libx264",       // Video codec
                    "-preset", "slow",       // Encoding preset for quality (choose according to your requirement)
                    "-crf", "18",            // Constant Rate Factor (lower is higher quality, typical range 18-28)
                    "-c:a", "aac",           // Audio codec
                    "-b:a", "320k",          // Audio bitrate
                    "-shortest",             // Stop when the shortest stream ends
                    mp4OutputPath            // Output MP4 file
            };

            Process process = Runtime.getRuntime().exec(command);
            process.waitFor();
            System.out.println("MP4 file created successfully: " + mp4OutputPath);
        }
        catch (IOException | InterruptedException e)
        {
            e.printStackTrace();

• pyInstaller : Pack binary executable inside project's executable to run

  18 décembre 2023, par zur

  TLDR ;

  


  I would like to pack the ffmpeg executable inside my own executable. Currently I am getting

  


  FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'
Skipping ./testFile202312061352.mp4 due to FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'


  


  Details :

  


  I am creating executable file using following command :

  


  pyinstaller cli.py \&#xA;  --onefile \&#xA;  --add-binary /Users/<machineuser>/anaconda3/envs/my_env/bin/ffmpeg:bin&#xA;</machineuser>

  


  The code that uses ffmpeg is not authored by me. And I would like to keep that part the same.

  


  When I run from command line while conda environment is active I can successfully run it as python (or perhaps anaconda) knows where the binaries are. I have a pretty empty cli.py. That seems to be the entry point and I hope if it is possible I can set the bin directory's path there ...

  


  I am able to successfully run the application like following :

  


  (my_env) machineUser folder % "dist/cli_mac_001202312051431" ./testFile202312061352.mp4


  


  I would like to run like following :

  


  (base) machineUser folder % "dist/cli_mac_001202312051431" ./testFile202312061352.mp4


  


  I would like to keep the world out side my executable's tmp folder the same. I would not want to change something that will be "left behind" after the exec is terminated.

  


  Question :

  


  Can some one please mention how to modify the pyinstaller command or what to change in cli.py to achieve it successfully ?
