第31行

img2webp -v -loop %loop% -lossy -q %q% -d %time%? %imgs% -o %DstFolder%\out_quality%q%_loop%loop%_frametime%time%.webp
复制代码

多了个问号，删除后如下，再试试看

img2webp -v -loop %loop% -lossy -q %q% -d %time%  %imgs% -o %DstFolder%\out_quality%q%_loop%loop%_frametime%time%.webp

    大神说的是对的，解决办法如下，其中imgs_len_Max可根据各自系统所支持的长度进行修改：

@echo off
setlocal enableDelayedExpansion
set "str_FF="
for %%b in (f e d c b a 9 8 7 6 5 4 3 2 1 0) do for %%c in (f e d c b a 9 8 7 6 5 4 3 2 1 0) do call set str_FF=!str_FF!%%b%%c
set "_strlen=set $=^!#1^!#&set $=^!$^!^!$^!^!str_FF^!&set/a##=0x^!$:~512,2^!"

set SrcFolder=E:\PS_Work\donggeng\face
set DstFolder=E:\Temp\webptest\out
set "imgs="
set /a imgs_len=0
set /a imgs_len_Max=7168
for /f "delims=\" %%a in ('dir /b "%SrcFolder%\*.png*"') do (
	set #1=%%~a
	(%_strlen%)
	set /a imgs_len+=##+3
	if !imgs_len! gtr %imgs_len_Max% (
		call :Exec_img2webp
		set "imgs="
		set /a imgs_len=##+3
	)
	set "imgs=!imgs!"%%a" "
)
if %imgs_len% gtr 0 call :Exec_img2webp
endlocal
pause
exit /b

:Exec_img2webp
set /a "loop=0"
set /a "times=40"
set /a "q=65"
pushd "%SrcFolder%"
img2webp.exe -v -loop %loop% -lossy -q %q% -d %times% %imgs% -o %DstFolder%\out_quality%q%_loop%loop%_frametimes%times%.webp 
popd
exit /b
