Description (last modified by )
When trying to map and copy time_id3 metadata from a .ts file to a .ts file, the time_id3 metadata is copied (e.g PRIV tags) but the ID3 header is not inserted (0x49 0x44 0x33).
ID3v2 header
The first part of the ID3v2 tag is the 10 byte tag header, laid out
as follows:
ID3v2/file identifier "ID3"
ID3v2 version $04 00
ID3v2 flags %abcd0000
ID3v2 size 4 * %0xxxxxxx
https://id3.org/id3v2.4.0-structure
% ffmpeg -i 3.ts -map 0:a -c:a copy -map 0:v -c:v copy -map 0:d -c:d copy -f mpegts 3b.ts ffmpeg version N-104633-g0e22d2e59b built with Apple clang version 12.0.0

I can confirm that. This is linked to this: http://ffmpeg.org/pipermail/ffmpeg-user/2023-June/056532.html
You can also reproduce it using the remux example, adapted to allow remuxing AVMEDIA_TYPE_DATA streams. Each time the streams are remuxed, the timed_id3 packets loose exactly 5 bytes..

I believe that this was closed with https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/468615f2045da325e0f73e8e668d49cf456ccb37
