使用ffmpeg将音频文件转换为mp3

我需要使用ffmpeg将音频文件转换为mp3。

当我把命令写成ffmpeg -i audio时。ogg -acodec mp3，我得到的错误:

我还运行了这个命令:

 ffmpeg -formats | grep mp3

得到的回应是:

我猜是mp3编解码器没有安装。我的思路对吗?

当前回答

批处理文件夹中的文件:

for i in *.wav; do ffmpeg -i "$i" -f mp3 "${i%}.mp3"; done

这个脚本将文件夹中的所有“wav”文件转换为mp3文件，并添加mp3扩展名

Ffmpeg必须安装。(见其他答案)

我必须清除我的ffmpeg，然后从一个ppa安装另一个:

sudo apt-get purge ffmpeg
sudo apt-add-repository -y ppa:jon-severinsson/ffmpeg 
sudo apt-get update 
sudo apt-get install ffmpeg

然后转换:

 ffmpeg -i audio.ogg -f mp3 newfile.mp3

1) wav转mp3

ffmpeg -i audio.wav -acodec libmp3lame audio.mp3

2) ogg到mp3

ffmpeg -i audio.ogg -acodec libmp3lame audio.mp3

3） AC3 到 MP3

ffmpeg -i audio.ac3 -acodec libmp3lame audio.mp3

4) aac转mp3

ffmpeg -i audio.aac -acodec libmp3lame audio.mp3

高质量的Mac OS工作完美!

Ffmpeg -i input.wma -q: 0输出。mp3

https://trac.ffmpeg.org/wiki/Encode/MP3

的VBR编码:

ffmpeg -vn -ar 44100 -ac 2 -q:a 1 -codec:a libmp3lame output.mp3

你可以使用这个命令:

ffmpeg -i input.wav -vn -ar 44100 -ac 2 -b:a 192k output.mp3

本例中使用的参数说明:

-i - input file -vn - Disable video, to make sure no video (including album cover image) is included if the source would be a video file -ar - Set the audio sampling frequency. For output streams it is set by default to the frequency of the corresponding input stream. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. -ac - Set the number of audio channels. For output streams it is set by default to the number of input audio channels. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. So used here to make sure it is stereo (2 channels) -b:a - Converts the audio bitrate to be exact 192kbit per second
