video/x-vp9 is required in the src pad, however the output includes a IVF header, which makes the pipeline below doesn't work gst-launch-1.0 videotestsrc ! msdkvp9enc ! msdkvp9dec ! fakesink Since mfx 1.26, the VP9 encoder supports bitstream without IVF header, so in this patch, the mfx version is checked and msdkvp9enc is enabled only if mfx 1.26+ is available
