Benjamin,

I checked this repo out, and built it along with pulling the latest
versions of G-streamer and fluster.
When I check for v4l2 compatibility, I get the following:

    GStreamer-H.264-V4L2-Gst1.0: GStreamer H.264 V4L2 decoder for
GStreamer 1.0... ❌
    GStreamer-H.264-V4L2SL-Gst1.0: GStreamer H.264 V4L2SL decoder for
GStreamer 1.0... ✔️
    GStreamer-AV1-V4L2SL-Gst1.0: GStreamer AV1 V4L2SL decoder for
GStreamer 1.0... ❌
    GStreamer-H.265-V4L2-Gst1.0: GStreamer H.265 V4L2 decoder for
GStreamer 1.0... ❌
    GStreamer-H.265-V4L2SL-Gst1.0: GStreamer H.265 V4L2SL decoder for
GStreamer 1.0... ❌
    GStreamer-VP8-V4L2-Gst1.0: GStreamer VP8 V4L2 decoder for GStreamer 1.0... ❌
    GStreamer-VP8-V4L2SL-Gst1.0: GStreamer VP8 V4L2SL decoder for
GStreamer 1.0... ✔️
    GStreamer-VP9-V4L2SL-Gst1.0: GStreamer VP9 V4L2SL decoder for
GStreamer 1.0... ✔️

I see H,264, VP8 and VP9, but I would have also expected
GStreamer-H.265-V4L2SL-Gst1.0 to return with a check box.

When I checked to see if both decoders were being enumerated, I found they were.
[gst-main] root@localhost:~/gstreamer/fluster# dmesg |grep -i hantro

Did I do something wrong, or did I miss something?
