使用 ffmpeg 传输自定义（所有）元数据

Question

How to transfer metadata using FFMPEG or other tools with CMD?

I'm trying to encode video/audio and since they already have metadata inside obviously i want to preserve them into my new file

btw since i'm using mediamonkey as main player, there's also some Custom metadata. this is the one who wont transfer

• for Video output file using mp4/mkv (using x264)
• for Audio output file using m4a (using neroAac)

Thank You!

ps. which container is best for neroAac and x264? since i can't seem to edit mkv metadata (when i remove from mediamonkey playlist, they're all gone), mp4 is fine though and i can't seem to play AAC, although it's fine when muxed into video

Answer 1

使用以下命令复制所有自定义和全局元数据标签信息：

ffmpeg <inputfile> -movflags use_metadata_tags -c copy  <outputfile>

Answer 2

It seems the following parameter did not work for reel_name.

'-movflags use_metadata_tags' '-metadata:s:v reel_name=ABCDE12345' '-map_metadata 0' '-map_metadata 0:g'

Please advice

as follow, please kindly find the testing result
