我有一个包含以下元数据的文件:
"Format_Level": "6.2",
"colour_range": "Full",
"colour_range_Source": "Container / Stream",
"transfer_characteristics": "PQ",
"transfer_characteristics_Source": "Container / Stream",
我想更改/添加元数据 - 是否可以在不重新编码视频文件的情况下更改这些数据?我需要哪些命令?
"Format_Level": "5.2",
"colour_range": "Limited",
"colour_range_Source": "Container",
"colour_range_Original": "Full",
"colour_range_Original_Source": "Stream",
"transfer_characteristics": "BT.709",
"transfer_characteristics_Source": "Container",
"transfer_characteristics_Original": "PQ",
"transfer_characteristics_Original_Source": "Stream",
