使用ffmpeg连接*.mkv文件
我对这件事几乎失去了理智，我肯定我错过了一些简单的事情 我有两个由OBS生成的*.mkv文件。更好的是，我只复制了一个文件两次，所以我确信我的比特率、fps、tbn都是一样的 那么我会：使用ffmpeg连接*.mkv文件,ffmpeg,video-processing,obs,Ffmpeg,Video Processing,Obs,我对这件事几乎失去了理智，我肯定我错过了一些简单的事情 我有两个由OBS生成的*.mkv文件。更好的是，我只复制了一个文件两次，所以我确信我的比特率、fps、tbn都是一样的 那么我会： ffmepg -i "concat:file1.mkv|file1_copy.mkv" -c copy test.mkv 它运行，我的屏幕上充满黄色消息： ffmpeg -i "concat:file1.mkv|file1_copy.mkv" -c copy test.mkv ffmpeg versi

- 将*重新编码为.mkv以修复此问题，因为.mkv有一个固定的tbn-它已经是.mkv了
- 问题是不同的比特率/tbs/fps/无论什么-现在，它们是相同的视频两次
- 使用
，-fflags+genpts
，-使用wallclock作为时间戳1
-据我所知，这些都不起任何作用，无论是在vsync 0-enc\u time\u base-1
之前还是-I-c copy
我已经没有主意了。我做错了什么。我不知道，但我怀疑发布
