我有一个原始 H264 视频，我试图通过以下命令将其转换为 MP4:
ffmpeg -i 'Camera 4(172.16.2.12_554)_1_2014_07_16_15_20_08.h264' 'Camera
4(172.16.2.12_554)_1_2014_07_16_15_20_08.mp4'
FFMPEG 不断丢弃所有帧。甚至没有编码 1 帧。
请看下面的输出:
Seems stream 0 codec frame rate differs from container frame rate:
2400000.00 (2400000/1) -> 24.00 (24/1)
Input #0, h264, from 'Camera 4(172.16.2.12_554)_1_2014_07_16_15_20_08.h264':

最佳答案
您可以尝试告诉 ffmpeg 输出文件中您想要的 fps:
只需键入以下内容:
ffmpeg -r "24" -i 'Camera 4(172.16.2.12_554)_1_2014_07_16_15_20_08.h264' 'Camera
4(172.16.2.12_554)_1_2014_07_16_15_20_08.mp4'
