我看过有关此问题的其他帖子，但似乎没有一个标志适用于我的。这是 bash 脚本的一部分，用于运行命令并在出现错误（例如断开连接时）时重新运行脚本。

cmd="ffmpeg \
    -stream_loop -1 -re -thread_queue_size 256 -i "$VIDEO" \
    -stream_loop -1 -re -thread_queue_size 256 -i "$AUDIO" \
    -re -thread_queue_size 256 -i "$AUDIO" \
    -filter_complex \
    "[1:a]volume=0.0[a1]; \
    [aout]" -map 0:v:0 -map "[aout]" \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:>
    -acodec aac -ac 2 -ar 44100 -threads 0 -b:a $AB \
    -f flv -rtmp_live live $URL/$KEY"

until $cmd ; do
        echo "restarting ffmpeg command..."
        sleep 2
done

然后当我运行 bash 脚本时出现错误，它会不断重新启动

Filter volume has an unconnected output

I've looked at other posts about this but none of the flags seem to work with mine. Here is part of the bash script that runs the command and re-runs the script when there's an error, like when it disconnects.

cmd="ffmpeg \
    -stream_loop -1 -re -thread_queue_size 256 -i "$VIDEO" \
    -stream_loop -1 -re -thread_queue_size 256 -i "$AUDIO" \
    -re -thread_queue_size 256 -i "$AUDIO" \
    -filter_complex \
    "[1:a]volume=0.0[a1]; \
    [aout]" -map 0:v:0 -map "[aout]" \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:>
    -acodec aac -ac 2 -ar 44100 -threads 0 -b:a $AB \
    -f flv -rtmp_live live $URL/$KEY"

until $cmd ; do
        echo "restarting ffmpeg command..."
        sleep 2
done

Then it keeps restarting when I run the bash script with the error
