使用 VLC 合併影片時遇到問題

我正在嘗試合併三個短視頻（每個視頻不到 10 秒）。這是我的命令：

vlc 1.mp4 2.mp4 3.mp4 --sout "#gather:std{access=file,dst=final.mp4}" --sout-keep

返回這個

VLC media player 3.0.7 Vetinari (revision 3.0.7-0-g86cee31)
[0000000000d7b400] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.

QObject::~QObject: Timers cannot be stopped from another thread

然後一切都崩潰了，輸出的視頻只是第一個視頻，沒有聲音。我的錯誤是什麼？
