Documentation and --help issue

[MilitantTurtle]

In Documentation:

https://docs.video2x.org/running/command-line.html

"Select which GPU to use with the --gpu, -g argument:"

Output from Video2X:

[2025-07-30 03:02:58] [critical] Error parsing arguments: unrecognised option '-g'
[2025-07-30 03:03:24] [critical] Error parsing arguments: unrecognised option '--gpu'

from --help it appears correct command is -d

-d [ --device ] arg (=0) Vulkan device index (GPU ID)

Also:

From help --aq-mode is not listed, so it is expected as an -e command as -e aq-strength=(x), however, it is not:

"[2025-07-30 03:10:12] [warning] Failed to set encoder option 'aq-mode' to '3': Option not found"

same with --aq-strength.

but from the output we can tell that these parameters have been set using defaults from video2x:

"x265 [info]: AQ: mode / str / qg-size / cu-tree : 2 / 1.0 / 32 / 1"

I can't find a way to change this in command line, I have tried --aq-mode as a non -e option, but this also doesn't work,

also there is no mention of VFR vs CFR anywhere in the documentation.

other expected extra commands do not work, but we can see from output that some of them are being used
such as:

[2025-07-30 03:10:12] [warning] Failed to set encoder option 'strong-intra-smoothing' to '0': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'rect' to '1': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'aq-mode' to '3': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'aq-strength' to '1': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'psy-rd' to '2.0': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'psy-rdoq' to '1.0': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'rdoq-level' to '1': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'tu-intra-depth' to '2': Option not found
[2025-07-30 03:10:12] [warning] Failed to set encoder option 'tu-inter-depth' to '2': Option not found

later in output we can see:

x265 [info]: tools: rect amp rd=6 psy-rd=2.00 rdoq=2 psy-rdoq=1.00 rskip mode=1
x265 [info]: tools: signhide tmvp b-intra strong-intra-smoothing deblock sao

thankfully some of them are the preferred settings, but we would still like to be able to change them, but documentation does not tell us how.
