嗨，我正在尝试将文件流式传输到Facebook，但我想启动视频命令的00:01:21中的流媒体，

ffmpeg -ss 00:01:20 \
-re -i 'My_Video.mp4' -f pulse -ac 2 \
-i default -pix_fmt yuv420p -c:v libx264 -s 1280x720 \
-preset veryfast -c:a aac -b:a 160k -ar 44100 \
-threads 0 -bufsize 1000k -vb 500k -maxrate 500k -deinterlace -g 30 -r 30\
-f flv -flvflags no_duration_filesize "rtmps://live-api-s.facebook.com:443/rtmp/MY_FACEBOOK_KEY"

但流在00:01:20中不启动，只需在00上定期启动：00：00.00，可能出了什么问题？谢谢大家的宝贵时间！
