使用 ffmpeg 从容器中丢弃数据流 [英] Discard data stream from container using ffmpeg

问题描述

我正在尝试使用 ffmpeg 删除 Mp4 容器中的数据(字幕)流.

I am trying to get rid of a data (subtitle) stream within a Mp4 container, using ffmpeg.

这是ffprobe的截图:

Here's the screenshot from ffprobe:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.m4v':

 **Unsupported codec with id 100359 for input stream 0**

我试过了:

 ffmpeg -i test.m4v -acodec copy -vcodec copy -sn nodata.mp4

数据轨道还在那里，只是从流 0 移到了流 2

Data track still there, just moved from stream 0 to stream 2

我也试过:

 ffmpeg -i test.m4v -acodec copy -vcodec copy -map 0:1 -map 0:2 no2.mp4

相同的结果，跟踪仍然在那里，只是跳到流 0:2 没有运气.

Same result, track still there, just jumped to stream 0:2 no luck.

有什么提示吗?提前致谢

Any hint? Thanks in advance

推荐答案

谢谢，我使用带有负值的 -map_chapters 选项解决了删除数据流的问题.

Thanks, I resolved using the -map_chapters option with negative value to remove the data stream.

完整字符串:

ffmpeg -i in.mp4 -c:v copy -c:a copy -map_chapters -1 out.mp4 

希望这会对其他人有所帮助！
