Does Nvidia Plugins remove GstMeta?

Tried adding GstMeta but when I add GstMeta on non-nvidia plugins pipeline, I can get them at the sink but if I add nvidia plugins to the pipeline I cannot get the metadata.

Does nvidia plugins remove GstMeta?

The metadata is removed by nvv4l2decoder. Attached a probe at the src and sink. At the sink I can get it but cannot get it add src. Should it remove the metadata, if so, how can I add the metadata.

Can this sample help you ?
We also opensource nvvl42decoder code. You can find it in “L4t source” -> https://developer.nvidia.com/embedded/downloads#?search=source

Hi,

I cannot find the nvv4l2decoder sources. Is there anywhere I can get it?

Found it “gst-nvvideo4linux2_src.tbz2”
