ffmpeg元数据

Question

I am encoding MPEG4/H264 to an mp4 file using libavformat (ie C libraries) I would like to add some metadata to the MP4 file such as date/time. Can someone give me some indication of how this can be done?

Thanks.

Answer 1

did you try the metadata tag? -metadata title="My Title" blahoutput.mp4

looking it over you can also use the -timestamp option
