avconv how to copy all stream and merge metadata (fix creation date)?
9,596
After reading the documentation and lots of searches i finally got the answer I wanted, the final command is:
avconv -i IN.mp4 -i METADATA.txt -map_metadata 1 -codec copy -map 0 OUT.mp4
This means:
- use the inputs:
IN.mp4
andMETADATA.txt
- map the metadata from input 1 (
METADATA.txt
) - copy all codecs (no transcoding)
- map all streams from input 0 (
IN.mp4
) - write to
OUT.mp4

I am trying to fix the metadata of some old videos, so i would like to copy all streams audio video and subtitle and merge the metadata from a txt file.
I first dump the metadata with:
avconv -i out.mp4 -f ffmetadata metadata.txt
And then try to copy with the metadata:
avconv -i MOV_0732.mp4 -f ffmetadata -i metadata.txt -c:v copy -c:a copy -c:s copy -map 0 out.mp4
But the final metadata is untouched, if i move the metadata arguments to the end avconv does not start:
