项目说明

利用opencv读取视频,重新编码为x264裸码流,并且生成保存每帧数据buffer size的二进制文件.

The video is read using opencv, re-encoded into an x264 raw-bitstream, and a binary file is created that holds the size of the data buffer per frame.

input

ffmpeg支持的各种格式的视频.

Various formats of video supported by ffmpeg.

output

• .h264 裸码二进制文件.
• .idx 保存帧数据长度大小的二进制文件,每帧4字节保存int类型.

用于某些不依靠码流分析,需要直接读取视频的场景.

For some scenes that do not rely on stream analysis and need to read the video directly.
