【问题描述】：
我不是 100% 确定我在这里问的问题是否正确，但基本上我想使用 VLC 将 4k 网络摄像头包装在传输流中，以便我可以将其用作 IPTV 服务器或在一些其他软件中进行排序.
到目前为止我所拥有的：
vlc dshow:// :dshow-vdev="Video (00 Pro Capture HDMI 4K+)" :dshow-adev="Audio (2- 00 Pro Capture HDMI 4K+)" :dshow-aspect-ratio=16\:9 :dshow-chroma=BGR32 :dshow-vcodec=libx265 :dshow-fps=60 :dshow-acodec=mp4a :dshow-ab=96 :dshow-channels=2 :dshow-samplerate=44100 :no-dshow-config :no-dshow-tuner :live-caching=100 :sout=#transcode{vcodec=h.264,acodec=mpga,vb=800,ab=128,deinterlace}:rtp{dst=227.0.0.1,port=8554,mux=ts}
使用上面的dshow 命令，我可以让图片在本地 VLC 会话中完美显示。使用 RTP 命令，我似乎已经成功地将视频卡在传输流中传输到一定程度，因为我可以在客户端 VLC 会话中从流中获取音频。
似乎出错的是转码。我为服务器 VLC 会话打印了下面的日志。 h.264 似乎不是有效的编解码器，mp4v 也不是（在我的机器上找不到）。
关于如何解决的任何建议？我目前正在为此撕毁我的头发......
