  • Using ffmpeg with libfdk-aac, encoding HE-AAC v1 and mono actually, but in decoding ffmpeg show HE-AAC v2 and stereo [closed]

    ffmpeg encode command :

    but decode this test.aac, I think HE-AAC and mono is corrent, but it show HE-AAC v2 and stereo, why ?

    what happened ? test.aac is also displayed as 2 channels in Audition. But 1 channel is displayed in MediaInfo, and ADTS header is corrent :

  • Using FFMPEG command to read the frame and show using the inshow function in opencv

    28 novembre 2024, par HARSH BHATNAGAR

    I am trying to get the frame using the ffmpeg command and show using the opencv function cv2.imshow(). This snippet gives the black and white image on the RTSP Stream link . Output is given below link [ output of FFmpeg link].
I have tried the ffplay command but it gives the direct image . i am not able to access the frame or apply the image processing.

  • Building my JAVA parameter array for FFMPEG

    29 janvier 2016, par user3541092

    FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
    built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)

    Machine : Amazon Linux t2.micro (free tier)

    Sample File : sample_iTunes.mov
    Sample File URL : https://support.apple.com/en-us/HT201549

    I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().

    ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -y

    NOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().

        String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "
    
            + "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";
    
    String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);
    
    p = Runtime.getRuntime().exec(_ffmpegCommand);
    
    BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
    String _line = null;
    

    
    while((_line = _reader.readLine()) != null) {
    
        lw.writeLine(_logPath + _logName, _line);
    
        System.out.println(_line);
    
    }

    I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.

    The following string array works :

    try
    
        {
    
            String[] _params = {"ffmpeg",
    
                       "-i",
    
                       String.format("%s", _inputFile),
    
                       "-pix_fmt",
    
                       "yuv420p",
    
                       "-c:v",
    
                       "libx264",
    
                       String.format("%s", _outPutFile),
    
                       "-y"};
    

    
            p = Runtime.getRuntime().exec(_params);
    

    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    
        }
    
        catch (Exception e) {
    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    

    
        }

    However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :

    try
    
        {
    
            String[] _params = {"ffmpeg",
    
                       "-i",
    
                       String.format("%s", _inputFile),
    
                       "-pix_fmt",
    
                       "yuv420p",
    
                       "-c:v",
    
                       "libx264",
    
                       "-vtag", // <---- New
    
                       "mp42", // <---  New
    
                       String.format("%s", _outPutFile),
    
                       "-y"};
    

    
            p = Runtime.getRuntime().exec(_params);
    

    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    
        }
    
        catch (Exception e) {
    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    

    
        }
