ffmpeg will sometimes go into an endless loop

[cofiem]

Sometimes, for unknown reasons, ffmpeg will going into an endless loop when converting audio. The process will end up being killed at the timeout.

This is what happens. Perhaps something like disabling interactive input might help ('Press [q] to stop')?

This seems to occur mainly for wav to wav conversions:

Seems to happen only on 6 hr 45 min duration wav files when seeking to near the end of the file (5h and later).
