如何在 macOS 中使用 FFmpeg 录制屏幕而不会出现此错误：“设备不支持所选的帧速率。”

  • 772

我正在尝试使用 macOS 上的 FFmpeg 录制屏幕。

首先我运行这个命令：

ffmpeg -f avfoundation -list_devices true -i ''

输出为：

[AVFoundation indev @ 0x12ff058a0] AVFoundation video devices:
[AVFoundation indev @ 0x12ff058a0] [0] FaceTime HD Camera
[AVFoundation indev @ 0x12ff058a0] [1] Capture screen 0
[AVFoundation indev @ 0x12ff058a0] AVFoundation audio devices:
[AVFoundation indev @ 0x12ff058a0] [0] MacBook Pro Microphone

然后我运行这个命令：

ffmpeg -f avfoundation -i 0:0 -fps_mode passthrough output.mp4

并且有一个错误：

[avfoundation @ 0x150705610] Selected framerate (29.970030) is not supported by the device.
[avfoundation @ 0x150705610] Supported modes:
[avfoundation @ 0x150705610]   1920x1080@[15.000000 30.000000]fps
[avfoundation @ 0x150705610]   1280x720@[15.000000 30.000000]fps
[avfoundation @ 0x150705610]   1080x1920@[15.000000 30.000000]fps
[avfoundation @ 0x150705610]   1760x1328@[15.000000 30.000000]fps
[avfoundation @ 0x150705610]   640x480@[15.000000 30.000000]fps
[avfoundation @ 0x150705610]   1328x1760@[15.000000 30.000000]fps
[avfoundation @ 0x150705610]   1552x1552@[15.000000 30.000000]fps

删除-fps_mode passthrough没有帮助。

如何修复？
