If formats are compatible on both sides of a nvvideoconvert, is it smart enough to pass the buffer through unmodified? Basically I want to know if there’s a cost to always using it between a source and stream muxer since some sources don’t necessarily allocate in NVMM and handling the NOFORMAT failure on link is lengthy and complicated.

Yes. When the formats and capabilities are exactly the same on sink pad and src pad of “nvvideoconvert”, the plugin will passthrough the buffer.
