Hello all,
I am trying to build the OpenCV 3.4.9 with nvjpeg library which support hardware acceleration on jpeg encoding and decoding. Howeve, it will always encounter issue. I would like to know whether anyone has successfully built one with nvjpeg support. I tried libjpeg-turbo. However, the decoding speed is still too slow for the Jetson tx2.
My build command is
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local \ -D WITH_CUDA=ON \ -D WITH_CUBLAS=ON -D ENABLE_FAST_MATH=ON -D CUDA_FAST_MATH=ON \ -D WITH_LIBV4L=ON -D BUILD_TESTS=OFF \ -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF \ -D WITH_QT=ON -D WITH_OPENGL=ON -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules \ -D WITH_JPEG=ON -D BUILD_JPEG=OFF \ -D JPEG_INCLUDE_DIR=/usr/src/jetson_multimedia_api/include/libjpeg-8b \ -D JPEG_LIBRARY=/usr/lib/aarch64-linux-gnu/tegra/libnvjpeg.so ..
Thank you very much!
