我想制作视频流，以便将其分发到流媒体中。
mp3文件是从视频文件中提取的（正在实时录制），当提取音频（MP3）时，我想把这个音频文件和图像一起传送到实时流媒体中。但是-re并不适用于此。
要提取音频文件我使用：
ffmpeg.exe -re -i file(LIVE).AVI -vn -ar 22050 -ab 16k -r 1 -ac 1 -f mp3 C:\Users\" & wshNetwork.Username & "\Documents\audio.mp3"
这项工作非常适合制作MP3文件。使用-re。
之后，我正在使用此命令将auvio文件与jpg图像混合：
ffmpeg.exe -loop 1 -f image2 -i c:\picture.jpg -re -i c:\Users\" & wshNetwork.Username & "\Documents\audio.mp3 -vb 10k -ar 22050 -ab 16k -ac 1 -r 1 -bufsize 300k -f webm www.adress.com
第二个命令无效，因为-re无效，并生成带有图片和不连贯音频的视频。
输出是：
