处理输入h264到h265时发现ffmpeg无效数据

我想将视频文件从h264转换为h265

到目前为止，我使用的命令适用于许多文件，但现在有些文件出现错误：

有问题的文件可以由例如mpv播放，因此它们不会损坏。

我将从第一个错误开始

流1的[matroska@0x1b09450]编解码器不使用全局标头，但容器格式需要全局标头

尝试包括以下内容以更正：“-flags+global_header”

要将h264转换为h265，可以在标准FFmpeg安装中使用以下命令（假设input.mp4是有效的h264文件）。不确定.mkv文件是否需要任何唯一标志，但请尝试一下

用于.mp4文件的命令：

ffmpeg-i/path/input.mp4-c:v libx265-c:a copy-flags+global_头/path/output.mp4

---

流1的错误编解码器不使用全局标头现在已消失，但仍会显示无效的章节开始。你知道如何删除章节吗（我不需要它们）？您的ffmpeg选项也出现了同样的错误。-映射单元章节-1有效，-映射单元元数据-1不幸没有。对这是有道理的。很高兴你明白了。干杯
