我是 ffpmeg 的新手，正在尝试通过 azuracast 进行 YouTube 电台直播。我在 Oracle Cloud 上创建了一个实例，并在那里安装了 azuracast。我可以收听我在 azuracast 中上传的歌曲，但是，每当我尝试使用我的公共页面进行直播时（参见下面的代码），代码似乎可以正常工作，但我从未在我的 YouTube 频道上看到直播。在流健康选项卡下，它始终显示当前未收到任何数据。
这是我开始直播的代码：
#! /bin/bash
VBR="1500k"
FPS="24"
QUAL="medium"
YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"
KEY="....-....-....-....-...."
VIDEO_SOURCE="/home/ubuntu/lofi_background.jpg"
AUDIO_SOURCE="http://141.144.229.46/radio/8000/radio.mp3"
ffmpeg \
-re -f lavfi -i "movie=filename=$VIDEO_SOURCE:loop=0, setpts=N/(FRAME_RATE*TB)" \
-thread_queue_size 512 -i "$AUDIO_SOURCE" \
-map 0:v:0 -map 1:a:0 \
-map_metadata:g 1:g \
-vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
-acodec libmp3lame -ar 44100 -threads 6 -qscale:v 3 -b:a 320000 -bufsize 512k \
-f flv "$YOUTUBE_URL/$KEY"
运行上述代码后我看到的结果如下：

所以我没有看到任何错误（虽然有一些警告，但我在谷歌上搜索了一下，它们可以忽略吗？）。我想这可能是由于防火墙造成的，于是我创建了一条新的出站规则，试图允许端口 1934、443。但是，仍然不起作用。
有人可以指导我吗？
提前致谢！
