If the documentation for Metadata is correct then there is a bug in

Give proof, otherwise you are not different from paid mockers that

this list.
See my initioal post in this thread. It proofs the "bug".

Nope, it proofs PEBKAC.



Paul you should read the documentation and then you'd realize that Ulf
is correct; his original attempt to replace the chapter metadata follows
the documentation and illustrates the problem.

Nope. If user read documentation at all, user would notice -map_chapters
option just below
-map_metadata option.



I was talking about the Metadata documentation referenced by Jim:

http://ffmpeg.org/ffmpeg-all.html#Metadata-1

"

By using the ffmetadata muxer and demuxer it is possible to extract metadata from an input file to an ffmetadata file, and then transcode the file into an output file with the edited ffmetadata file.

Extracting an ffmetadata file with ffmpeg goes as follows:

ffmpeg -i INPUT -f ffmetadata FFMETADATAFILE

Reinserting edited metadata information from the FFMETADATAFILE file can be done as:

ffmpeg -i INPUT -i FFMETADATAFILE -map_metadata 1 -codec copy OUTPUT
