获取视频编码信息 接下来,我们需要获取视频文件的编码信息。我们可以通过OpenCV的get方法来获取视频文件的编码信息。下面是所需的代码: codec_info=video.get(cv2.CAP_PROP_FOURCC) 1. 输出编码信息 最后,我们需要将获取到的编码信息输出出来。下面是所需的代码: print("Video codec: {}".format(codec_info)) 1...

我们首先创建一个FFProbe对象,然后使用streams.video属性来获取视频流信息,进而获取编码格式。 逻辑说明 导入ffprobe库; 定义get_video_codec函数,接受视频文件路径作为参数; 创建FFProbe对象,并传入视频文件路径; 使用streams.video属性获取视频流信息; 获取视频流的编码格式; 返回视频的编码格式。 2. opencv库 安装...
