"stream size" keep old size after transcoding

[Nosirus]

I try to start again from scratch my plugins by taking inspiration from the great work done by others (I start in coding) but I have a problem with ffmpeg, some mkv keeps the statistics after transcoding, like the stream size. (it seems that handbrake doesn't have this problem.)

it seemed to me that "-map 0 -map_metadata:g -1" solved this problem but not and -map_metadata -1 makes me lose languages...

I refuse no help ! see same suggestion :)

I will always need help with this problem.

I tried to run "Tdarr_Plugin_JB69_JBHEVCQSZ_PostFix" but without success, can the language of the tracks be retrieved and then reintegrated?

I thought of "var lang = file.ffProbeData.streams[i].MediaLanguageCode;" something like this for each stream (audio and subtitle)
