请注意,你需要将 /path/to/nvidia_video_codec_sdk/ 替换为实际的SDK安装路径。 重新编译或运行项目,检查 cudacodec::videowriter 是否可以正常工作: 在配置完SDK路径后,你需要重新编译你的项目,并运行它以确保 cudacodec::videowriter 可以正常工作。 如果一切配置正确,你应该能够使用 cudacodec::videowriter 来写...
It is a compile time dependancy. As you have discovered if it cannot be found, NVCUVID is missing from the cmake output but you can still compilecv::cudacodec. However it is not implemented, because nvidia-video-sdk is not available, and you get the error messages you observed. Also wh...
找了可能原因 : https://github.com/opencv/opencv/issues/10201 Hello, I've just walked through all the same issues and can share my experience. Here is how I've successfully compiled my project withcv::cudacodec::VideoReader My setup: Ubuntu16.04 OpenCV 3.4.1 CUDA 9.1 CMake 3.5.1 Copydy...
上次我们简单介绍了OpenCV及计算机视觉的定义，今天我们继续说说基础知识。今天主要讲Python和图像基本处理。

codec on GPU. The most difficult part of JPEG algorithm is entropy codec, and we've accomplished that task on GPU as well. Our solution for fast JPEG on CUDA is working on GPU and we've accelerated all constituent parts of JPEG algorithm. This is actually the main idea of image ...
