Audio 使用ffmpeg将尼康3200D相机的MOV文件转换为中间（mpegts）格式-音频问题

我正在使用SO上的命令将MOV转换为中间格式。这个中间步骤的原因是能够连接一系列MOV文件

出于某种原因，当我运行以下命令时：

ffmpeg -i source.mov -c copy -bsf:v h264_mp4toannexb -f mpegts dest.ts

我失去了音频

我尝试添加

-bsf:s PCMs16le

，但这并没有改变物联网

这是输出

从输出来看，它确实看起来像我复制了视频流和音频流。那么问题出在哪里？

你怎么知道你“丢失了音频”？嗯。我从未尝试在TS中使用PCM。将音频编码到aac或mp3是否可以接受？是的，将音频编码到mp3是绝对可能的。。。我丢失了音频，因为当我播放它或将它进一步转换为mp4时，我听不到音频。

ffprobe

对

dest.ts

说了什么？
