How to add metadata to webm

[we...@pythian.com]

Hi,

I need to add custom metadata information (such as starttime, environmentId etc.) to my webm video file. I tried to use ffmpeg -metadata command, however, it doesn't work with custom attributes. Do you know how this is supported in webm? and how to do it?

Thank you very much for your help.

Best Regards,

Tao

webm and mkv support custom tags; you might try cross posting on ffmpeg-users with the full command line you were using.

 

Thank you very much for your help.
