我正在尝试将 Sony Vegas 的 AVC 文件转换为 MP4 文件，以便在 DaVinci Resolve（不支持 .avc）中使用。因为我不想花几个小时重新编码视频，所以我想使用该-copy codecs选项。但是，它给了我“pts 没有值”错误。我读过互联网上的其他帖子，包括这个网站上的一个帖子，他们都建议使用-fflags +genpts。然而，这并不能解决问题。我尝试使用的当前输入是：
ffmpeg -fflags +genpts -i camcord.avc -codec copy camcord.mp4
输出结果如下：

我检查了输出文件，它似乎播放得很好。这是否意味着 pts 错误应该仍然存在并且可以安全地忽略？
