FFmpeg-请求的输出格式'mpeg'不是合适的输出格式 [英] FFmpeg - Requested output format 'mpeg' is not a suitable output format

问题描述

我正在尝试使用FFmpeg将视频从mp4格式转换为mpeg，以便可以合并多个视频.我有一个FFmpeg的自定义版本，可以在其中控制配置选项:

I am trying to use FFmpeg to convert a video from mp4 format to an mpeg, so that I can merge multiple videos. I have a custom build of FFmpeg where I control the configuration options:

ffmpeg -y -i VID_20150514_171122_12085.mp4 -an -f mpeg VID_20150514_184208.mp4.0.mpg

但是我仍然收到错误消息，提示请求的输出格式'mpeg'不适合输出格式".相同的命令似乎在具有完整版本FFmpeg的Ubuntu计算机上也可以使用.我想念什么?我以为我已经启用了所有的mpeg编码器/解码器... mpeg，mpegvideo，mpeg1video，mpeg2video.

But I keep getting an error saying "Requested output format 'mpeg' is not a suitable output format". The same command seems to work on my Ubuntu machine with a full build of FFmpeg. What am I missing? I thought I had all the mpeg encoders/decoders enabled ... mpeg, mpegvideo, mpeg1video, mpeg2video.

推荐答案

可能使用的结果<代码> - 禁用-一切然后不使能适当的选项.使用此选项时，我经常会看到这种情况.使用此选项后，需要一些反复试验才能获得所需的一切.

Probably the result of using --disable-everything and then not enabling the proper options. I see this often when this option is used, and It will take some trial and error to get everything you need after using this option.

尝试添加-enable-muxer = mpeg .
