This does not sound correct:
The h264_nvenc encoder (always) produces h264 output, it cannot output anything
else.
The h264_nvenc encoder only accepts nv12 input while most other encoders accept
yuv420p. Semantically, yuv420p and nv12 are identical, an encoder that accepts
both (and that runs single-threaded and produces deterministic output) would
produce identical output if the „same“ nv12/yuv420p data is provided as input.
