mfh265enc

This element encodes raw video into H265 (HEVC) compressed data.

Example pipelines

 gst-launch-1.0 -v videotestsrc ! mfh265enc ! h265parse ! qtmux ! filesink location=videotestsrc.mp4

This example pipeline will encode a test video source to H265 using Media Foundation encoder, and muxes it in a mp4 container.
