Comment (by curtis69):

 Many hours of search lead me to this minimal command line :

 ffmpeg -i test.avi -ab 128k -ar 44100 -ac 2 -f flv -s 640x480 test.flv

 One more time, output length seems to be random (it can be full length, or
 just the begin, ...)

 How to know if ffmpeg meet a problem but stop encoding without notice ?
 (ram, ...)
 I see no error in ffmpeg output
