  • Error at the stage initialization ffmpeg

    13 juin 2017, par Sasha Tsvigun

    I am developing an ios application to display an online stream through a rtsp link from IP cameras using the FFMPEG library. I’ve successfully added all the libraries and headers, successfully built the project. But at the initialization stage of the ffmpeg framework, when calling the function av_register_all () ; in the DidFinishLaunchingOutNOptions method, I get the following error.

    "_av_register_all", referenced from:
    
clang: error: linker command failed with exit code 1 (use -v to see invocation)

    enter image description here

    If the function is commented - there is no error and the project is successfully started

    I understand that the problem is not great, but I can not solve it on my own. Maybe someone will tell how to solve it ?
    Thanks for any advice !

  • How to convert mo4 to mp3 in android java ?

    3 août 2023, par Akshit

    I have the mp4 link of a video but don't have a link for the mp3 version of that mp4 video. So is there any way that I can convert that mp4 video to mp3 in Android ? I saw some resources but nothing works for me. I have two ways in which I believe this can be achieved

    


      

    1. Convert the mp4 link to mp3 directly. ( Not Sure if this is achievable )

      2. 


    2. Download the mp4 on the device with the help of a link and then use some code to convert that mp4 to mp3.

      3. 


    


    I also tried some solutions which are available online

    


    https://github.com/tanersener/mobile-ffmpeg

    


    I tried the above library to achieve the final goal. But got Async command execution failed with returnCode=1. This error in the code I am using is

    


        private class Mp4ToMp3ConverterTask extends AsyncTask {

    @Override
    protected String doInBackground(String... params) {
        String mp4FilePath = params[0];
        String mp3OutputPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/output.mp3";

        String[] ffmpegCommand = {"-i", mp4FilePath, "-vn", "-ar", "44100", "-ac", "2", "-b:a", "192k", mp3OutputPath};


        Config.enableStatisticsCallback(new StatisticsCallback() {
            public void apply(Statistics newStatistics) {
                Log.d("Dekh", String.format("frame: %d, time: %d", newStatistics.getVideoFrameNumber(), newStatistics.getTime()));
            }
        });

        long executionIdd = FFmpeg.executeAsync(ffmpegCommand, new ExecuteCallback() {

            @Override
            public void apply(final long executionId, final int returnCode) {
                if (returnCode == RETURN_CODE_SUCCESS) {
                    Log.i("Dekh", "Async command execution completed successfully.");
                } else if (returnCode == RETURN_CODE_CANCEL) {
                    Log.i("Dekh", "Async command execution cancelled by user.");
                } else {
                    Log.i("Dekh", String.format("Async command execution failed with returnCode=%d.", returnCode));
                }
            }
        });

        FFmpeg.cancel(executionIdd);

        return mp3OutputPath;
    }
}


    


    Solution number 2 which I used is

    


    https://androidprogrammatically425516919.wordpress.com/2020/04/21/how-to-convert-video-to-audio-in-android-programmatically/

    


    But I got an error here also Failed to instantiate extractor. and another error is java.io.FileNotFoundException : open failed : EISDIR (Is a directory)
I tried the online available solution to solve these errors but nothing worked. Such as granting write permission. Providing a valid location to save the output.

    


    But nothing work so far. Please help me on this. Thank you
