Following the issue https://gitlab.com/mobian1/devices/sunxi64-linux/-/issues/13, any H264 playback using cedrus results in a red screen due to the wrong pixel format negociated between `v4l2slh264dec` and `glimagesink`. The video sink is `glimagesink` which is negociating a NV12 with `v4l2slh264dec` despite a GST_VIDEO_FORMAT_NV12_32L32 detected with a different colorspace (`NV12 - 420` vs `NV12_32L32 - 422`) https://gitlab.com/mobian1/devices/sunxi64-linux/uploads/0ae9c2a5b4b656f09f9e5bc3e7d049bc/bug_salmon.jpeg `gst-launch-1.0 filesrc location=Salmon.mp4 ! qtdemux ! v4l2slh264dec` Needs a converter or add the support of `NV12_32L32` to glimagesink
