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.
