Friends,
I wish to write meta data to a mp4 file.
specifically i wish to write the ednoded date as it is found in a probe
by media info
example / here is a snip from media info
...
Encoded date : UTC 2014-11-05 05:02:03
Tagged date : UTC 2014-11-05 05:02:03
...
I *think this used to work ... circa 2013 , maybe
is it possible that it worked before the "new" -map N:N for audio came
about?
|ffmpeg -i input -c copy -map 0 -metadata creation_time="2015-06-07
08:09:10" output.mp4|
|but I get an error of
Data stream encoding not supported yet (only streamcopy)
|
|when i do this ( complete console )
|

---------------------------------
|
|my Q might be:
Is it possible to
|write
Encoded date : UTC 2014-11-05 05:02:03
Tagged date : UTC 2014-11-05 05:02:03
into the metadata or -itags so that i can change that Encoded date
|------------------------------------
|
|ffprobe shows this metadata stuff
|
| ffprobe -loglevel quiet -show_format ~//Videos/ShupeJarArtVideo/sjp_0.mp4
shows

Thanks much
best wishes
shupe
