实现"python read_video 比特率"流程 实现步骤 步骤一:安装必要的库 在Python中,我们可以使用OpenCV库来处理视频文件。首先,你需要安装OpenCV库,可以通过以下代码来安装: $ pip install opencv-python 1. 步骤二:读取视频文件 接下来,我们需要编写代码来读取视频文件。下面是读取视频文件的代码: i
*_=read_video(path,output_format="TCHW",pts_unit="sec")height,width=video_tv.shape[-2:]# shape=[..., H, W]print("torchvision",f"{height=},{width=}")video_av=av.open(path)frame_av=next(video_av.decode())height,width=frame_av.height,frame_av.widthprint("av",f"{height=},...
