GstCUDA offers two basic CUDA algorithm library examples. They are designed for the '''''cudafilter''''' element and works just out of the box, so they are perfect for training and giving the first steps on GstCUDA. The idea is to give detailed examples on how to use the '''''cudafilter''''' element, and also to give some examples of written code of a functional (out of the box) CUDA algorithm library for the '''''cudafilter''''' element. The CUDA algorithm library examples are built automatically, and you can find them under the following paths:

The cudamux CUDA algorithm library example is automatically built, and you can find it under the following path:
* '''''$GstCUDA_DIR/tests/examples/cudafilter_algorithms/memcpy/memcpy.so'''''
* '''''$GstCUDA_DIR/tests/examples/cudamux_algorithms/mixer/mixer.so'''''
* '''''$GstCUDA_DIR/tests/examples/cudafilter_algorithms/gray-scale-filter/gray-scale-filter.so'''''


The '''''memcpy.so''''' CUDA algorithm library consists in a very basic algorithm that receives a full-color YUV I420 image and generate and exact copy of the incoming image. It is a basic image filter that copies the luminance and chrominance components of the incoming image. The image copy is executed on the GPU, so it is hardware accelerated, that assures an optimal performance. This basic algorithm is just for example and demonstration purposes, because it shows the capability of GstCUDA to execute an algorithm on the GPU that go through each pixel in the incoming image and copies it to the output image. This can be a high load task if we consider a 4K@60fps video stream, due to the high data transaction rate, but GstCUDA could handle it with no problem.  
The '''''mixer.so''''' CUDA algorithm library consists in a very basic algorithm that receives two YUV I420 images as inputs and mixed them on the GPU, this
generates an output image that is the average of the two input images. All the processing of the images is done in the GPU. This basic algorithm is just for example and demonstration purposes, because it shows the capability of GstCUDA to execute an algorithm on the GPU that go through each pixel in the incoming images, process them and generate and output image.


The '''''gray-scale-filter.so''''' CUDA algorithm library consists in a very basic algorithm that receives a full-color YUV I420 image and convert it to a gray-scale YUV I420 image. It is a basic image filter that modifies the chrominance components of the image by assigning a fixed value that makes the image to look in gray-scale. All the processing of the image is done in the GPU.
Below you will find a set of test pipelines with their respective performance stats for the mixer CUDA algorithm library.

This page gives an usage example of the cudamux element.


Introduction

GstCUDA offers one basic CUDA algorithm library example, designed for the cudamux element that works just out of the box, so it is perfect for training and giving the first steps on GstCUDA. The idea is to give detailed examples on how to use the cudamux element, and also to give some examples of written code of a functional (out of the box) CUDA algorithm library for the cudamux element. The cudamux CUDA algorithm library example is automatically built, and you can find it under the following path:

  • $GstCUDA_DIR/tests/examples/cudamux_algorithms/mixer/mixer.so

The mixer.so CUDA algorithm library consists in a very basic algorithm that receives two YUV I420 images as inputs and mixed them on the GPU, this generates an output image that is the average of the two input images. All the processing of the images is done in the GPU. This basic algorithm is just for example and demonstration purposes, because it shows the capability of GstCUDA to execute an algorithm on the GPU that go through each pixel in the incoming images, process them and generate and output image.

Below you will find a set of test pipelines with their respective performance stats for the mixer CUDA algorithm library.

Note: To get the best performance on the Tegra platform, you must execute the jetson_clocks.sh script. This script tune-up the Tegra to high performance mode. All the reported performance stats came from tests done after ran the jetson_clocks.sh script. Execute command: sudo ~/jetson_clocks.sh
