Mit älteren ffmpeg Versionen hat man des öfteren das Problem das aktuelle Videos nicht konvertiert werden können, da das Format erst in der aktuellen SVN Version unterstütz wird.
Häufig bei Formaten die von neueren Videokameras erstellt werden.

Das sieht dann z.B. so aus:

$ ./ffmpeg -i ./testvideo-aus-einzelbildern-erstellt.avi -vpre libx264-main -b 1200k -ab 128k ./testvideo-aus-einzelbildern-erstellt.mp4

Seems stream 0 codec frame rate differs from container frame rate: 3000.00 (3000/1) -> 29.67 (89/3)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from './testvideo-aus-einzelbildern-erstellt.avi':
  Duration: 00:00:30.00, start: 0.000000, bitrate: 114185 kb/s
    Stream #0.0(eng): Video: Y'CbCr 4:2:2 - yuyv, 640x480, PAR 1:1 DAR 4:3, 29.67 tbr, 3k tbn, 3k tbc
    Stream #0.1(eng): Audio: pcm_s16le, 44100 Hz, stereo, s16, 1411 kb/s

swScaler: Unknown format is not supported as input pixel format.
Cannot get resampling context.

Abhilfe schafft hier ein frisches ffmpeg aus dem SVN.

Um die Erstellung der Binärdatei zu automatisieren bietet sich hier ein Script an.

Um ffmpeg mit dem Script compilieren zu können, müssen die als Kommentar am Scriptanfang genannten Tools installiert sein.
Da ich macports installiert habe, kann es sein das weitere Tools/Librarys benötigt werden. Sollte dies der Fall sein bitte ein Komentar hinterlassen und ich passe das Script dahingehend an.
