Does not support transmission on VP9?

[spf-tanabe]

Hi @gpolitis @Toumassa

I would like you to tell me about VP9.
I checked with attached sample code, but as long as I check the vp9 package,
transmission on VP9 requires the implementation of the following three.
How about that?

• These have not been implemented
  • org.jitsi.impl.neomedia.codec.video.vp9.Packetizer
  • org.jitsi.impl.neomedia.codec.video.vp9.VPXDecoder
  • org.jitsi.impl.neomedia.codec.video.vp9.VPXEncoder

• vp9 package
  https://github.com/jitsi/libjitsi/tree/master/src/org/jitsi/impl/neomedia/codec/video/vp9

• Related issue
  Are there plans to support VP9? #388
  fixes plain VP9 #432

• Sample code

public class TestVideoStream {
            public static void main(String[] args) {
                        LibJitsi.start();
                        MediaService mService = LibJitsi.getMediaService();
                        List<MediaDevice> devices = mService.getDevices(MediaType.VIDEO,  MediaUseCase.CALL);
                        MediaDevice device = devices.get(0);
                        MediaStreamImpl mStream = (MediaStreamImpl)  mService.createMediaStream(device);
                        mStream.setDirection(MediaDirection.SENDONLY);
                        MediaFormat format =  mService.getFormatFactory().createMediaFormat("VP9",  MediaFormatFactory.CLOCK_RATE_NOT_SPECIFIED);
                        mStream.addDynamicRTPPayloadType((byte) 99, format);
                        mStream.setFormat(format);
                        mStream.setConnector(new DefaultStreamConnector());
                        mStream.start();
            }
}
