ffmpeg：从mp3删除lame replaygain标签

Question

lame is writing a replaygain tag if the option --noreplaygain is not set: 如果未设置选项--noreplaygain正在编写一个--noreplaygain标签：

ffmpeg -i testgain_0.mp3
Input #0, mp3, from 'testgain_0.mp3':
Duration: 00:01:00.42, start: 0.025057, bitrate: 192 kb/s
Stream #0:0: Audio: mp3, 44100 Hz, stereo, s16p, 192 kb/s
Metadata:
  encoder         : LAME3.99r
Side data:
  replaygain: track gain - -12.500000, track peak - unknown, album gain - unknown, album peak - unknown,

Can I use ffmpeg to remove the "Side data"? 我可以使用ffmpeg删除“边数据”吗？ In my trys with map metadata I cannot access this "Side data" to remove it: -map 0:0 -map_metadata -1 在尝试使用map metadata我无法访问此“侧面数据”以将其删除： -map 0:0 -map_metadata -1

Answer 1

It appears to get removed if you roundtrip it via MP4. 如果您通过MP4往返传输，则似乎已将其删除。

ffmpeg -i testgain_0.mp3 -c copy testgain_0.mp4

ffmpeg -i testgain_0.mp4 -c copy nogain_0.mp3

Or use a pipe for a single-step method: 或将管道用于单步方法：

ffmpeg -i testgain_0.mp3 -c copy -f avi - | ffmpeg -i - -c copy nogain_0.mp3
