Encode/decode VP8 or VP9 with Gstreamer?

manpreet Best Answer 2 years ago

I'm trying to find a way to use VP8 or VP9 compressed video, a part of Googles WebM project with Gstreamer.

Is there a already a module that can handle VP8? If so, can I get some simple example of how to use it in a broadcast/receive over RTP?

So far there is nothing on the Gstreamer official documentation. They have Matroska support but that seems only be for demuxing the container.

Edit There obviously are ways

Server:

gst-launch-0.10 -v v4l2src ! video/x-raw-yuv,width=640,height=480 ! vp8enc ! rtpvp8pay ! udpsink host=127.0.0.1 port=9001

Client:

gst-launch-0.10 udpsrc port=9001 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)VP8-DRAFT-IETF-01, payload=(int)96, ssrc=(uint)2990747501, clock-base=(uint)275641083, seqnum-base=(uint)34810" ! rtpvp8depay ! vp8dec ! ffmpegcolorspace ! Autovideosink

But the latency is higher than I expected.
