for H.264 video (You will need to have libx264 installed for this to work). You can play around with the bitrate because it depends on the size of your frames what bitrate you will need. Also, running ffmpeg -formats will display all of the output formats and codecs if you want to experiment more.

该命令的输出质量很差，原因如下：
尝试类似：
对于 mpeg 4 视频或：
对于 H.264 视频（您需要安装 libx264 才能正常工作）。您可以调整比特率，因为它取决于帧的大小以及您需要的比特率。此外，如果您想进行更多实验，运行 ffmpeg -formats 将会显示所有输出格式和编解码器。
有关更多选项，请参阅 ffmpeg 文档。
