VLC命令行：RTSP到mp4文件（视频+音频）

Question

赢7 x64。

当我在VLC播放器中观看此链接时，一切都很好：

rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov

当我尝试捕获文件链接并显示时：

• 显示没有声音的视频。
• 创建的文件无法播放。

命令：

vlc.exe -vvv "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" --sout="#transcode{venc=ffmpeg,vcodec=mp4v,vfilter=canvas{width=800,height=600},aenc=ffmpeg{strict=-2},acodec=mp4a}:duplicate{dst=display,dst=standard{access=file,mux=mp4,dst=video.mp4}"

日志中存在一些错误，例如：MPEG4GenericRTPSource Warning: Unknown or unsupported "mode": AAC-hbr。这是我的问题的原因吗？如何解决我的问题？
