修剪视频并添加水印和音乐背景时，在流＃2中找不到编解码器h264的标签

如何解决修剪视频并添加水印和音乐背景时，在流＃2中找不到编解码器h264的标签

我正在将视频切成块，然后加入它们，并使用以下命令添加水印和背景音乐。

"[-y,-i,/storage/emulated/0/WhatsApp/Media/WhatsApp Video/VID-20200726-WA0154.mp4,/storage/emulated/0/FXMotion/.cache/.watermark/logo_watermark.png,-stream_loop,-1,/storage/emulated/0/WhatsApp/Media/WhatsApp Documents/DripReport_-_Skechers_(Lyrics)(MP3_160K).mp3,-filter_complex,[1:v]scale=640/4:-1[logo1];[0:v]trim=0:2.483,setpts=PTS-STARTPTS[v1];[0:v]trim=2.483:7.45,setpts=2.0*(PTS-STARTPTS)[v2];[0:v]trim=7.45:9.933,setpts=PTS-STARTPTS[v3];[v1][v2][v3]concat=n=3:v=1[video];[video][logo1]overlay=main_w-overlay_w-10:main_h-overlay_h-10[vw],-map,[vw],2,-c:v,libx264,-crf,23,-preset,veryfast,-shortest,/storage/emulated/0/FXMotion/FXMotion-200810e.mp4,-hide_banner]"

但是运行时出现以下错误：

我在以下位置运行ffmpeg：

{设备 “ os_version”：“ 10” “型号”：“ SM-A217F” “ brand”：“ samsung”

}

如何解决？谢谢前进！

解决方法

音频文件有两个流：MP3流和封面图像。通过使用-map,2,，两个流都被映射。 ffmpeg还将把封面图像也转换为H.264，但这不是封面图像可接受的编解码器。由于您大概不需要保留封面，因此请勿映射。 -map,应该成为-map,2:a,
