We don't provide support for user scripts here: just the actual ffmpeg
commands. We're not here to debug scripting issues which is often where
problems originate.

What's with the weird re-direct?

Why are you using neroAacEnc instead of an encoder supported by ffmpeg,
such as libfdk_aac?

With what player?

How can we duplicate the issue? You need to show your actual, unscripted
commands and the complete console output for each. If specific inputs
are required to reproduce the issue then please provide them.
