正确的 VLC 转码编解码器

Question

我不是 100% 确定我什至在这里问了正确的问题，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，我似乎已经在一定程度上成功地以传输流传输视频卡，因为我可以从客户端 VLC 会话中的流中获取音频。

似乎出错的一点是转码。 我已经为服务器 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）。

有关如何修复的任何建议？ 我目前正在为此撕毁我的头发......

尝试根据您的网络需要调整以下参数（可以通过 VLC 命令行完成）：

"--network-caching=33", 
"--file-caching=33", 
"--live-caching=33",
"--clock-synchro=0", 
"--clock-jitter=0",
"--h264-fps=60",
"--avcodec-fast",
"--avcodec-threads=1"
