  • Sound in videos is full of static

    13 avril 2015, par banshee_walk_sly

    I’m trying to play sound from an FFMpegFrameGrabber by getting the Frame and sending the audio samples to a SourceDataLine. Here’s what I have so far :

    Creating the SourceDataLine :

    int channels = _grabber.getAudioChannels();
    
int format = _grabber.getSampleFormat();
    
AudioFormat fmt = new AudioFormat(_grabber.getSampleRate(), format, channels, true, true);
    
_sourceDataLine=(SourceDataLine)AudioSystem.getLine(new DataLine.Info(SourceDataLine.class, fmt));
    
_sourceDataLine.open(fmt);
    
_sourceDataLine.start();

    Attempting to play sound (images are handled in the else block) :

    org.bytedeco.javacv.Frame f = _grabber.grabFrame();
    

    
if (f.samples != null && f.samples.length > 0)
    
{
    
    byte[] bytes = new byte[4096];
    
    for (Buffer buffer : f.samples)
    
    {
    
        FloatBuffer floatBuffer = (FloatBuffer) buffer;
    
        ByteBuffer byteBuffer = ByteBuffer.allocate(floatBuffer.capacity() * 4);
    
        byteBuffer.asFloatBuffer().put(floatBuffer);
    
        byteBuffer.rewind();
    
        byteBuffer.get(bytes);
    
        _sourceDataLine.write(bytes, 0, bytes.length);
    
    }
    
}

    (Note : I tried a few different versions of this and they all have static. The versions I tried included combining the buffers into one large buffer, only trying to play one sample instead of each channel, and changing the audio format to many different permutations.)

    The problem is the sound is full of static, and almost completely unintelligible. This is my first time doing any audio programming, so I’m sure I’m doing something completely ridiculous.

    I appreciate any help. Thank you.

    EDIT

    In response to Radiodef, I tried a number of AudioFormats, and I couldn’t find one that worked for PCM_FLOAT. I found an example that used this :

    fmt = new AudioFormat(AudioFormat.Encoding.PCM_FLOAT, _grabber.getSampleRate(), format, channels, channels, _grabber.getSampleRate(), true);

    Note : I tried a few different values for the framesize from examples : channels * format / 8, channels * 8 with a hardcoded samplerate of 64, channels * 4 with a hardcoded samplerate of 32, and any combinations of those

    But it give me this exception :

    java.lang.IllegalArgumentException: No line matching interface SourceDataLine supporting format PCM_FLOAT 44100.0 Hz, 8 bit, stereo, 2 bytes/frame,  is supported.
    
    at javax.sound.sampled.AudioSystem.getLine(Unknown Source)
    
    at com.enplug.player.video.Video.<init>(Video.java:52) &lt;- where I get the SourceDataLine
    
    ...
    
</init>

    EDIT 2

    Sorry for the delay. I appreciate all the help Radiodef.

    Here is some output from the FFMpegGrabber that is automatically output.

    I have two videos I’m testing with, and the first one (which is the one in the example above) has the following :

    Bit rate: 247 kbps

Audio sample rate: 44 kHz

    And the second is :

    Bit rate: 161 kbps
    
Channels: 2 (stereo)
    
Audio sample rate: 48 kHz

    They’re both mp4s, and I can provide any details about the video itself if needed.

    As for the library, yeah I’m pretty locked into JavaCV. We already have videos running without sound, but we’re now trying to add sound to our program.
