OpenCV：FFMPEG：编解码器不支持标签 0x34363268/'h264'

Question

像在 Mac OS 10.13.6 上一样安装 opencv 后：

conda install -c conda-forge ffmpeg
conda install -c conda-forge opencv

fourcc = cv2.VideoWriter_fourcc('h', '2', '6', '4')并在视频编剧中使用

我收到错误：

OpenCV: FFMPEG: tag 0x34363268/'h264' is not supported with codec id 27 and format 'mp4 / MP4 (MPEG-4 Part 14)'
OpenCV: FFMPEG: fallback to use tag 0x31637661/'avc1'

如何修复它？

Answer 1

你应该改变：

fourcc = cv2.VideoWriter_fourcc('h', '2', '6', '4')

到：

fourcc = cv2.VideoWriter_fourcc(*'avc1')
