Dann habe ich versucht, ein spezielles Programm wie abzurufen:
ffmpeg -i INPUT -map 0: p: 1344 OUTPUT
Es gelingt stark, aber das einzige, was ich bemerkt ist:
es scheint, transcode (decode & wieder kodieren) auf die Ausgabe implicitely anzuwenden?

Wenn ja, könnte ich die Umcodierung von Befehl zu vermeiden? Oder ist es notwendig? Es ist ein Bedürfnis, WARUM?
