如何使用VLC在命令行中保存视频流？ [英] How to save video stream using VLC in commandline?

问题描述

我尝试使用VLC在Window 7 Basic上的命令行中保存在线视频。

I'm trying to save online video using VLC in command line on Window 7 Basic.

这里有一些我尝试和部分工作：

Here are few things I tried and worked partially:

I:\movies> vlc http://media.ch9.ms/ch9/7492/a92ae0a6-7b81-4114-b102aa055d147492/E2EMeijerBrachaDartMonadsContinuations.wmv --sout="#duplicate{dst=std{access=file,mux=wmv,dst='file.wmv'}, dst=display}"

它在流式播放时播放视频，流到 file.wmv 。但保存的视频没有音频！

It plays the video while streaming, and it also saves the stream to file.wmv. But the saved video doesn't have audio! The command worked partially.

youtube的另一个尝试：

Another try for youtube:

I:\movies> vlc http://www.youtube.com/watch?v=TFr6G5zveS8 --sout="#duplicate{dst=std{access=file,mux=wmv,dst='file.wmv'}, dst=display}"

相同的结果：保存的视频无音频。我将 mux = wmv，dst ='file.wmv'更改为 mux = webm，dst ='file.webm'在命令行中，并再次运行：

Same result: saved video without audio. I changed mux=wmv,dst='file.wmv' to mux=webm,dst='file.webm' in the command line, and ran again:

I:\movies> vlc http://www.youtube.com/watch?v=TFr6G5zveS8 --sout="#duplicate{dst=std{access=file,mux=webm,dst='file.webm'}, dst=display}"

它只创建了文件，但不是视频或音频。我再次尝试 mux = mp4，dst ='file.mp4'。相同的结果：视频或音频，但它创建了该文件。

It only created the file, but neither video nor audio. Again I tried mux=mp4,dst='file.mp4'. Same result : neither video nor audio, but it created the file.

任何想法如何解决这个问题？

Any idea how to fix this problem? What am I missing?

至于使用 vlc 版本，命令 vlc --version 给出：

As for which version of vlc I'm using, the command vlc --version gives this:

VLC version 2.0.6 Twoflower (2.0.6-7-g729aa7a)
Compiled by fun on fat (Apr  8 2013 23:22:26)
Compiler: gcc version 4.6.3 (GCC) 

推荐答案

-acodec 和 vcodec

示例：

"C:\Program Files\VideoLAN\VLC\vlc.exe" -vvv dshow:// :dshow-vdev="USB Video Device" --sout=#transcode{vcodec=mp2v,fps=60,width=1080,acodec=mp2a,scale=1,channels=2,deinterlace,audio-sync}:standard{access-file,mux=ps,dst="C:\SPI3-Lite\VideoOutput\test1.mpg}
