Question

我有一个原始H264视频，我试图通过命令转换为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不断删除所有帧。甚至不编码1帧。

请参阅下面的输出：

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':

Answer 1

您可以尝试告诉ffmpeg您想要输出文件的fps：

只需输入以下内容：

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'

FFMPEG删除所有帧
