[...] Es kann zu Problemen kommen wenn man MP4s mit x264 Streamen möchte. Man erkennt es wenn erst das ganze Video runter geladen wird, bevor es anfängt zu spielen. Das liegt an einer falschen Reihenfolge des Header/Data Teils im Video. Sollte man dieses Problem haben, kann qt-faststart helfen. qt-faststart wird mit ffmpeg ausgeliefert.

@pim, @Chris

personally i wrap qt_faststart with both timelimit and nice.
`timelimit -t 1800 nice qt_faststart …`

this allows qt_faststart to run for a maximum of 30 minutes in an extreme case.
the nice command also allows for the command to be run at a low priority and to refrain from locking the system up, using idle resources.

especially if this machine is to perform other tasks, this is also most useful when scripting sequential usage with ffmpeg (which is also wrapped with nice) in which the script may be running more than once at a time.

It works great when it works!

I just wish it wouldn’t hang on corrupted files, and instead died with an error message to stderr.
