使用FFmpeg问题流式传输到YouTube

Question

我正在尝试播放我在YouTube内创建的直播活动。我正在尝试流式传输已创建的视频。我正在使用的命令如下所示。

我遇到的问题是，YouTube正在显示Streaming状态（附图片）并且似乎正在接收数据。但是直播活动中没有声音也没有图片。我不确定问题是什么。

ffmpeg -re -y -i input.mp4 -vcodec libx264 -b:v 600k -r 25 -s 640x360 -filter:v yadif -ab 64k -ac 1 -ar 44100 -f flv "rtmp://a.rtmp.youtube.com/live2/KEY"

显示YouTube直播状态的图片：

控制台输出：

编辑 -

我现在测试了下面的代码，但我仍然得到任何图片或声音..但youtube中的健康状况仍然显示良好

我先运行此命令

ffmpeg -i input.mp4 -vcodec libx264 -preset medium -maxrate 3000k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -acodec libmp3lame -b:a 128k -ac 2 -ar 44100 file.flv

然后我跑了

ffmpeg -re -i file.flv -codec copy -f flv rtmp://a.rtmp.youtube.com/live2/<KEY>

我仍然没有得到任何照片

我也在1

中尝试了完整的命令

ffmpeg -re -i input.mp4 -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/<key>  

仍然没有快乐
