[FFmpeg-devel] [PATCH 1/2] fftools/cmdutils: fix error message for "ffmpeg -init_hw_device list"

[Jun Zhao]

From: Jun Zhao <mypopydev at gmail.com>

When running 'ffmpeg -init_hw_device list' to display available hardware
devices, it incorrectly shows an error message:
"Failed to set value 'list' for option 'init_hw_device': Immediate exit requested"

This is a regression introduced by commit a50f90f1c23. The command is
actually working as intended - it should exit after listing devices, but
shouldn't display an error message.
