Also ich habe etwas mit ffmpeg rumgespielt. dabei ist mir aufgefallen, dass ich zwar videos in sämtliche format wandeln kann, audio allerdings nur in mp2(!).
ffmpeg -formats zeigt eine vielzahl von audioformaten an, funktionieren tut es aber nicht. das sieht dann beispielsweise so aus:
wenn ich das mp3 durch mp2 ersetze, dann funktionierts. wenn ich aber beispielsweise vorbis, mp3 oder aac wähle, geht es nicht.
jetzt noch ffmpeg -formats:
irgendwelche vorschläge, wie ich mein audio-im-video-proble löse?

several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported for example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats its even
