OpenCV with libnvjpeg

[DaneLLL]

1. Do I understand right that libnvjpeg.so can be used both on Tegra (with Tegra Encoder/Decoder module utilized) and on any CUDA enabled machine (with CUDA utilized)?

No. It only runs on TX1/TX2. There is JPG HW component in TX1/TX2. It is not a CUDA implementation.

2. Does libnvjpeg.so depend on libjpeg.so?

No. libnvjpeg.so is to modify the source code of libjpeg.so to have HW acceleration.

3. Can I link both libnvjpeg.so and libjpeg.so?

I think no. The function names are the same and it may trigger double definitions.

We suggest users use NvJpegEncoder and NvJpegDecoder classes.
