我在 Windows 上安装了 ffmpeg，我想将 MP4 文件流式传输到 Facebook 直播。视频带有音轨。
我正在运行以下命令：
ffmpeg
-re -i video.mp4
-acodec libmp3lame
-b:a 128k
-pix_fmt yuv420p
-profile:v baseline
-bufsize 6000k
-maxrate 1500k
-deinterlace
-vcodec libx264
-preset veryfast
-g 30
-r 30
-f flv
-flvflags no_duration_filesize
"rtmps://live-api-s.facebook.com:443/rtmp/mykey"
此命令恰好运行 14 帧然后停止。
然后，我收到以下错误：转换失败。
我尝试流式传输到 AWS IVS。但我遇到了完全相同的错误。
有人知道我的命令出了什么问题吗？
