Has I420 been removed in gstreamer nvcodec?

Application Development
1

In Debian 12 with gstreamer 1.22.0, nvcodec has the I420 support:

docker run -e NVIDIA_DRIVER_CAPABILITIES=compute,video,utility --privileged --gpus "device=GPU-63bc0b91-2265-1b94-831c-15c41fe92675" --rm -it --entrypoint=bash debian:12
    
apt update
apt upgrade      
apt install gstreamer1.0-plugins-bad gstreamer1.0-tools
gst-inspect-1.0 nvh264enc
# In Capabilities, video/x-raw has I420 format
# format: { (string)NV12, (string)YV12, (string)I420, (string)BGRA, (string)RGBA, (string)Y444, (string)VUYA }

In Debian13 with gtreamer 1.26.2. I can no longer see I420:

docker run -e NVIDIA_DRIVER_CAPABILITIES=compute,video,utility --privileged --gpus "device=GPU-63bc0b91-2265-1b94-831c-15c41fe92675" --rm -it --entrypoint=bash debian:13
      
apt update       
apt upgrade
apt install gstreamer1.0-plugins-bad gstreamer1.0-tools
gst-inspect-1.0 nvh264enc
# In Capabilities, video/x-raw does NOT have I420 format
# format: { (string)NV12, (string)Y444, (string)VUYA, (string)RGBA, (string)RGBx, (string)BGRA, (string)BGRx }

Has I420 been removed in nvcodec somewhere between gstreamer 1.22 and 1.26?

Just to confirm this is not Debian issue. I also tried Fedora 43 which has gstreamer 1.26.5, and also don’t see I420

docker run -e NVIDIA_DRIVER_CAPABILITIES=compute,video,utility --privileged --gpus "device=GPU-63bc0b91-2265-1b94-831c-15c41fe92675" --rm -it --entrypoint=bash fedora:43
yum install gstreamer1-plugins-bad-free
gst-inspect-1.0 nvh264enc
# In Capabilities, video/x-raw does NOT have I420 format
# format: { (string)NV12, (string)Y444, (string)VUYA, (string)RGBA, (string)RGBx, (string)BGRA, (string)BGRx }

If I try the same with fedora:38 which has gstreamer 1.22, gst-inspect-1.0 nvh264enc shows I410 format, just like in Debian 12 which also has gstreamer 1.22

I am trying to narrow down the version, and tested it gstreamer 1.24 (fedora:40 and ubuntu:24.04). gst-inspect-1.0 nvh264enc still shows the I420 format, so apparently it got dropped after 1.24.

Yes. It’s gone. Here’s the commit: nvcodec: Add new Direct3D11/CUDA mode encoder implementation (60735ded) · Commits · GStreamer / gstreamer · GitLab (I think)
