Conversion of audio in FFMpegFrameGrabber about javacv HOT 6 OPEN

Yes, that's right, it's not supported yet. If you have some changes to 
contribute, please attach them here for review! Thanks

BTW, FFmpegFrameRecorder does support audio conversion, so it should be 
possible to refer to it and do something similar in FFMpegFrameGrabber.

I am going to upload the changes i've made to FFMpegFrameGrabber once i have it 
sorted.

Thanks

Hi, I'm facing the same problem. Could anyone provide the fix of 
FFMpegFrameGrabber?
I really need it asap.

Thanks

Hi, I'm desperate, I do not get sound on this file to sound good. The ringing 
sound is full of noise. Can someone help me out? or show me how I do it? Thank 
you very much.
