About video encoding sample code using GPU

Hello every one.

I am investigating video encoding using GPU.
So, I have a question.

1.Do you use the GPU for the encode processing of the following sample code?
~/tegra_multimedia_api/samples/01_video_encode
~/tegra_multimedia_api/samples/03_video_cuda_enc

 -> I think that both are using hardware encoders, are they correct?

2.Does NVIDIA VIDEO CODEC SDK use CUDA?
Can I use it with JETSON TX 1?

3.If both the questions 1 and 2 are not using the GPU, is the sample program of the video encoding using the
GPU somewhere in JetPack for L4T?

Sorry to trouble you, but thank you for your answer.

Hello,

  1. yes. hardware codec.
  2. No. That’s not for Tegra.
  3. There are a lot of CUDA sample codes in L4T release, but no video encoding samples.
