vp9enc
This element encodes raw video into a VP9 stream. VP9 is a royalty-free video codec maintained by Google. It's the successor of On2 VP3, which was the base of the Theora video codec.
To control the quality of the encoding, the target-bitrate, min-quantizer, max-quantizer or cq-level properties can be used. Which one is used depends on the mode selected by the end-usage property. See Encoder Parameters for explanation, examples for useful encoding parameters and more details on the encoding parameters.
Example pipeline
gst-launch-1.0 -v videotestsrc num-buffers=1000 ! vp9enc ! webmmux ! filesink location=videotestsrc.webm
This example pipeline will encode a test video source to VP9 muxed in an WebM container.
