我正在尝试连接一些文件而不进行重新编码，因此我使用
ffmpeg -f concat -i list.txt -c copy out.mp4
在本地运行完美，但在专用服务器上视频抖动！就像视频冻结了几毫秒。
此外，我还有 1900 行输出，如下所示：
DTS -118059162071706656, next:2581328 st:0 invalid dropping
PTS -118059162071705632, next:2581328 invalid dropping st:0
[mp4 @ 0x25cb340] pts has no value
有什么问题？我需要在 ffmpeg 中安装其他东西吗？在这里您可以看到输出并查看 ffmpeg 配置。希望您能帮助我。谢谢。
