ffmpeg处理输入h264到h265时发现无效数据

Question

我想将视频文件从h264转换为h265。

我使用了很多文件，至今工作的命令，但现在我得到一个错误的一些文件：

有问题的文件是通过例如MPV可玩的，所以他们没有损坏。

Answer 1

我会从第一个错误开始。

[Matroska的@ 0x1b09450]编解码器流1不使用全局头部，但容器格式需要全球性的标题

尝试包括以下内容correc说： “-flags + global_header”。

而要将h264转换为h265，您可以使用以下命令与标准的FFmpeg install（假设input.mp4是有效的h264文件）。不知道是否有.mkv文件需要任何唯一的标志，但尝试一下。

命令我使用的.mp4文件：

的ffmpeg -i /path/input.mp4 -c：v libx265 -c：副本-flags + global_header /path/output.mp4
