我有一个旧的戴尔 MCE 遥控器，我想将其重新用于远程控制mpv。
我正在运行 Kubuntu 20.04，mpv版本为 0.32 和1.18.0-2build1。我已在中ir-keytable设置。当我测试远程ir-keytablerc6_mce.toml/etc/rc_keymaps和 ir-keytable -t，遥控器的每个按键均正确报告，共45个键。
但是，当我mpv --input-test --force-window --idle再次运行并按下按键时，几乎没有按键被注册：
input: Key DEL is bound to:
input: 1. 'script-binding osc/visibility' in <builtin>:1 (default)
input: Key DEL is bound to:
input: 1. 'script-binding osc/visibility' in <builtin>:1 (default)
input: Key ENTER is bound to:
input: 1. 'playlist-next' in <builtin>:1 (default)
input: Key RIGHT is bound to:
input: 1. 'seek 5' in <builtin>:1 (default)
input: Key LEFT is bound to:
input: 1. 'seek -5' in <builtin>:1 (default)
input: Key DOWN is bound to:
input: 1. 'seek -60' in <builtin>:1 (default)
input: Key UP is bound to:
input: 1. 'seek 60' in <builtin>:1 (default)
input: Key 0x21ff56 is bound to:
input: (nothing)
input: Key 0x21ff56 is bound to:
input: (nothing)
input: Key 0x21ff32 is bound to:
input: (nothing)
input: Key PLAY is bound to:
input: 1. 'cycle pause' in <builtin>:1 (default)
input: Key FORWARD is bound to:
input: 1. 'seek 60' in <builtin>:1 (default)
input: Key REWIND is bound to:
input: 1. 'seek -60' in <builtin>:1 (default)
input: Key CANCEL is bound to:
input: (nothing)
input: Key 0x21ff1c is bound to:
input: (nothing)
input: Key PAUSE is bound to:
input: 1. 'cycle pause' in <builtin>:1 (default)
我的input.conf不应该包含任何干扰内容，它也没有在输入测试中引用。为了完整起见：
input.conf
Shift+RIGHT frame-step
Shift+LEFT frame-back-step
R add sub-scale +0.1
Y add sub-scale -0.1
H seek -65
h seek 65
v cycle deband
a cycle audio
s cycle sub
i cycle interpolation
t script-message-to seek_to toggle-seeker
+ add audio-delay 0.010
- add audio-delay -0.010
F1 add sub-delay -0.1
F2 add sub-delay +0.1
F4 cycle-values video-aspect-override "16:9" "4:3" "2.35:1" "-1"
此外，一些键（例如SLEEP、、VOLUME_UP和VOLUME_DOWN）MUTE会直接传递到操作系统并执行其功能，这可以通过 KDE 弹出窗口看到。（SLEEP虽然只是将我注销）。
总结一下：即使在尝试输入测试时，遥控器上的 4 个键也会对系统起作用，4 个键只显示一个键码（不同于ir-keytable），尽管可以ir-keytable完美识别它们，并且在 的输入测试中只注册了 11 个键mpv。一个键（DEL）似乎被分配给了遥控器上的两个键。
此外，当我尝试从遥控器添加未分配的键到时input.conf，运行mpv会出现错误：
[input] Unknown key 'KEY_NEXT' at /etc/mpv/input.conf:17
[input] Unknown key 'KEY_PREVIOUS' at /etc/mpv/input.conf:18
似乎缺少了一些东西来让其mpv识别正确设置的红外遥控器ir-keytable。
我需要做什么才能正确分配按键和mpv操作？
