Unable to record with sample code on about javacv HOT 4 CLOSED

Do NOT use AV_PIX_FMT_YUV422P9LE. Instead please try to use AV_PIX_FMT_YUV420P.

And please post your questions on the mailing list next time if possible, thank 
you.

Hi Samual

Alright,I will make sure I use mailing list from now onwards . 
AV_PIX_FMT_YUV420P did the trick . Looks like I need to go back to basics . BTW 
recording worked but no sound was there. Any Ideas ?

Thanks
Arvind

To get sound, we have to record audio from somewhere. There's a sample for 
Android here for that:
https://github.com/bytedeco/javacv/blob/master/samples/RecordActivity.java
But nothing for Java SE yet. If you'd like to provide a sample that works with 
Java Sound:
https://docs.oracle.com/javase/tutorial/sound/capturing.html
It would be very welcome. Let me know! Thanks

There are wonderful people on the internet, I found this recording code . Will 
work more on this,

    // path of the wav file
    File wavFile = new File("/home/arvind/RecordAudio.wav");

    // format of audio file
    AudioFileFormat.Type fileType = AudioFileFormat.Type.WAVE;

    // the line from which audio data is captured
    TargetDataLine line;

    /**
