将ffmpeg流传输到sox rec [英] Pipe ffmpeg stream to sox rec

问题描述

我正在通过ffpmeg读取音频流，如下所示:

I am reading an audio stream via ffpmeg like this:

ffmpeg -i http://icecast.radiovox.org:8000/live.ogg -f mp3 filename

并希望通过管道将其发送给sox命令:

and want to pipe it to a sox command:

rec filename rate 32k silence 1 0.1 3% 1 3.0 3%.

最终，我要实现的目标是从脱口秀节目的实时Icecast流中录制音频.我只想录制个人讲话.每当有寂静时，我想停止录音，并在他们再次讲话后开始新的录音.

Ultimately, what I am trying to achieve, is to record the audio from a live Icecast stream of a talk show. I only want recordings though of the individual's speaking. Everytime there is silence, I want to stop the recording and start a new one once they start speaking again.

推荐答案

您遇到了什么困难?我尝试了一下，使用sox手册页中给出的示例时发现的唯一问题是sox -可能很难从几个字节理解输入格式.

What difficulty did you meet? I tried myself and the only problem I noticed in using the example given in the sox man page is that sox - may have trouble understanding the input format from just a few bytes.

尝试通过flac，它在这里有效:

Try going through flac, it worked here:

ffmpeg -i http://icecast.radiovox.org:8000/live.ogg -f flac - | sox - song.ogg silence 1 0.50 0.1% 1 2.0 0.1% : newfile : restart

ffmpeg -i http://icecast.radiovox.org:8000/live.ogg -f flac - | sox - song.ogg silence 1 0.50 0.1% 1 2.0 0.1% : newfile : restart
