 Replying to [comment:1 Balling]:

 > Of course you can ship h264, you cannot ship libx264. NVDEC is not going
 to work without h264, just like the encoder. NEVER. And maybe cuvid
 decoders/encoders may allow this, but I doubt it and they are deprecated
 anyway.

 The hardware encoders work just fine with having the ffmpeg h264 and hevc
 software stuff disabled and stripped.
