mfvp9enc

This element encodes raw video into VP9 compressed data.

Example pipelines

 gst-launch-1.0 -v videotestsrc ! mfvp9enc ! matroskamux ! filesink location=videotestsrc.mkv

This example pipeline will encode a test video source to VP9 using Media Foundation encoder, and muxes it in a mkv container.
