我已经成功使用exec_pushRTMPNGINX模块将FFMPEG直播流转换为HLS。
接下来我想做的是将来自同一源的音频流发布到Icecast位于同一服务器上的 。根据我的研究， 似乎ffmpeg无法广播到Icecast，因此我转向VLC。我尝试了多种通过 SSH 的命令组合来实现这一点。以下是我设法从这些组合中构建出来的，它们给我的警告最少：
vlc -vvv 'rtmp://localhost/stream/here' --no-sout-video --sout "#transcode{vcodec=none,acodec=aac,ab=128,channels=2, channel_layout=stereo,samplerate=44100}:gather:std{access=shout{mp3, bitrate=128, samplerate=44100, channels=2},mux=ogg, channel_layout=stereo,dst=source:pass@domain:8000/mount, select=novideo}" --sout-keep
我会将此命令的输出添加到这个问题的末尾，因为它很长。
这将建立一个连接，Icecast我可以在Icecast的管理页面上看到它。您也可以使用播放器（如VLC或 ）连接到它WMP并获取正确的标题，但它不会播放任何音频。如果我关闭ffprobe流Icecast，它会挂起，直到流退出。
我不知道该vlc命令是否产生了不好的音频，或者是否因为我忽略了与实时流相关的一些事情。如果我将输入换成标准文件，它的行为将相同并在短时间后退出，就好像它已经将文件从头到尾作为编码进行了处理一样。
我知道我可以很好地利用ffmpeg，所以我想尝试用它进行初步的音频转换，然后将输出通过管道vlc传输到Icecast。说实话，我可能把事情搞得一团糟，因为我可以看到输出在我的 SSH 终端上流动，而不是从尝试中获得任何类型的流。
我无法确切地说出那次尝试是什么，但从我粘贴的内容来看，它应该是这样的（有和没有#transcode）：
ffmpeg -i *input* -acodec libfaac -b:a 128k -ac 2 -f adts - | vlc - --no-sout-video :sout=#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=shout,mp3,dst=*serverinfo*} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep
当前设置允许人们NGINX使用 Flash media Live Encoder 3.2、AAC Audio @ 128k、44100、立体声进行流式传输。H.264 ~200k。进行这些尝试的原因是仅使用 1 个编码器即可启用多个流式传输。
我的问题是：
- 我是否遗漏了原始
VLC命令中的任何内容，从而导致流程混乱，或者 - 我剩下的警告是否会阻止我正在尝试做的事情？
- 我是否错过了一种更简单的方法来实现我想做的事情？
