Поиск музыкального файла через mplayer в терминале

Базовая навигация:

Вам нужны следующие базовые навигационные клавиши для MPlayer, которые будут работать во время воспроизведения клипа:

Basic keys: (complete list in the man page, also check input.conf)
 <-  or  ->       seek backward/forward 10 seconds
 down or up       seek backward/forward  1 minute
 pgdown or pgup   seek backward/forward 10 minutes
 < or >           step backward/forward in playlist
 p or SPACE       pause movie (press any key to continue)
 q or ESC         stop playing and quit program
 + or -           adjust audio delay by +/- 0.1 second
 o                cycle OSD mode:  none / seekbar / seekbar + timer
 * or /           increase or decrease PCM volume
 x or z           adjust subtitle delay by +/- 0.1 second
 r or t           adjust subtitle position up/down, also see -vf expand

Конечно, это можно увидеть на страницах руководства, но небольшой выбор, показанный здесь, взят из списка, показанного простым запуском команды mplayer в окне терминала.

Сложная навигация и управление:

Если вам нужен более сложный элемент управления , вы можете создать файл input.conf в каталоге $HOME/.mplayer и поместить его в этот файл содержит следующие детали:

##
## MPlayer input control file
##
## You are able to redefine default keyboard/joystick/mouse/LIRC bindings, or
## add new ones here.
## See DOCS/tech/slave.txt for possible commands that can be bound.
## Also see mplayer -input cmdlist for other possible options.
## The file should be placed in the $HOME/.mplayer directory.
##
## If you wish to unbind a key, use key ignore.
## e.g. ENTER ignore

## OSD Menu movement keys
##
## If you are using only the keyboard it is enough to define one command (like
## "menu up"), because then that single key will display the menu, which can
## then be navigated with the cursor keys and ENTER (defined in menu.conf).
##
## LIRC users should bind each "menu" command to a button on their remote.
##
## The set_menu command directly displays the (sub)menu specified as
## its argument. Usage should be self-explanatory (although not likely
## to be needed), after reading input.conf.

Потратьте столько времени, сколько вы хотите, чтобы настроить эти параметры:)

Работать над чем-то еще:

Что касается работы во время воспроизведения клипа: моя собственная практика - открывать новое окно терминала, но другой вариант - открывать другую вкладку в существующем окне терминала, если это поддерживается.
