Windows下使用批处理随机播放文件

先开好接收端

socat -u TCP-LISTEN:12345,fork,reuseaddr SYSTEM:"ffplay -autoexit -f wav -"

可以设置低延迟

socat -u TCP-LISTEN:12345,fork,reuseaddr SYSTEM:"stdbuf -o0 ffplay -nodisp -autoexit -fflags nobuffer -flags low_delay -infbuf -af anull -probesize 32 -analyzeduration 0 -f wav -"

@echo off
setlocal enabledelayedexpansion

set SERVER_IP=10.85.11.2
set PORT=12345

:: 初始化变量
set i=0

:parse_args
if "%~1"=="" goto build_done

:: 判断是否是目录
if exist "%~1\" (
    pushd "%~1" >nul 2>nul
    for /r %%f in (*) do (
        set /a i+=1
        set "arg[!i!]=%%~ff"
    )
    popd
) else if exist "%~1" (
    set /a i+=1
    set "arg[!i!]=%~1"
)

shift
goto parse_args

:build_done
if %i%==0 (
    echo No valid files found.
    pause
    exit /b
)
set count=%i%

:: 无限随机播放
:loop
set /a randIndex=%random% %% count + 1
call set "filepath=%%arg[!randIndex!]%%"

title !filepath!
ffmpeg.exe -re -i "!filepath!" -f wav tcp://%SERVER_IP%:%PORT%
goto loop
