I ran gst-inspect to see what showed up with 265 in the name.
# gst-inspect-1.0 |grep 265
libav: avdec_h265: libav HEVC (High Efficiency Video Coding) decoder
rtp: rtph265depay: RTP H265 depayloader
rtp: rtph265pay: RTP H265 payloader
typefindfunctions: video/x-h265: h265, x265, 265
v4l2codecs: v4l2slh265dec: V4L2 Stateless H.265 Video Decoder
videoparsersbad: h265parse: H.265 parser
It appears I have both h265parse and v4l2slh265dec.

gst-launch-1.0 appsrc num-buffers=0 ! h265parse ! v4l2slh265dec ! fakesink

Does this mean I have a wrong version of the kernel and/or incomplete patches?
