使用xfade过滤器（ffmpeg）播放多个视频时重复的帧
我一直在用音频合并多个视频。这在我之前合并的大多数视频中都适用，但在一些视频中，我收到了“复制超过1000帧”的警告，输出视频被破坏（一些视频无法播放，只有静态图片和声音未对齐） 所有视频的格式都相同。我看到的唯一区别是一些是“yuvj420p（pc）”，而大多数是“yuv420p”。但我尝试在没有“yuvj420p（pc）”的情况下进行合并，但没有任何帮助 已经尝试添加“-vsync vfr”，也没有帮助。 有趣的是，如果我删除第二个或最后一个输入视频，则不会给出任何警告，而且一切正常 我使用的命令是：使用xfade过滤器（ffmpeg）播放多个视频时重复的帧,ffmpeg,concatenation,concat,Ffmpeg,Concatenation,Concat,我一直在用音频合并多个视频。这在我之前合并的大多数视频中都适用，但在一些视频中，我收到了“复制超过1000帧”的警告，输出视频被破坏（一些视频无法播放，只有静态图片和声音未对齐） 所有视频的格式都相同。我看到的唯一区别是一些是“yuvj420p（pc）”，而大多数是“yuv420p”。但我尝试在没有“yuvj420p（pc）”的情况下进行合并，但没有任何帮助 已经尝试添加“-vsync vfr”，也没有帮助。 有趣的是，如果我删除第二个或最后一个输入视频，则不会给出任何警告，而且一切正常 我使用

建议提供一个仍然显示问题的最小命令。@llogan我希望我可以。这就是问题所在。。如果我删除一个输入视频，一个交叉淡入淡出和修剪的东西得到正常和视频组装好。少了一个视频，“复制了1000多帧”就消失了。你能提供所有11个输入文件的链接吗？只需在28个输入视频上分别运行xfade和triimng+crossfade。它是有效的。输出文件的持续时间几乎相同。这有帮助吗？ffprobe的两个输出文件：另一个更新-我刚刚合并了视频和音频，一切都完全同步。为什么这不能一次成功对我来说仍然是个谜。
