CUDA H264编码源代码

NVIDIA CUDA Accelerated H.264 Encoder This sample uses the NVCUVENC library to encode H.264 elementary stream. The library for encoding (NVCUVENC.DLL) is distributed with the NVIDIA drivers. The command line encoder takes the following inputs: cudaEncode.exe [input.yuv] [config.cfg] [output.file] [input.yuv] - must be a YUV file and can a collection of frames. The sample YUV file has 200 frames. [config.cfg] - configuration file for all of the settings in the CUDA Encoder [output.file] - output elementary stream. The CUDA encoder can output either H.264 elementary stream files. The output from this tool is H.264 video file. The test below was running on a GT200 class hardware, but it will work with any CUDA capable GPU with R185 drivers or newer. Some of parameters are only available with newer drivers.
