Batch avi to image sequence using ffmpeg [SOLVED]

[Whale Cooper]

Hey guys! Long story short.
I'm using ffmpeg to convert .avi file into a .png image sequence. This one works just fine:

Code: Select all

@ ECHO OFF

FOR %%A IN (*.avi) DO CALL :avi2png "%%A"

:avi2png
ffmpeg.exe -y -i %* -sameq -f image2 -c:v png "%%03d.png"

ECHO.
GOTO :EOF

But I want the script to extract the name without the extension from .avi file that is currently being processed. This is what the image sequence should look like: currentavi001.png, currentavi002.png etc. The script I came up with isn't working:

Code: Select all

@ ECHO OFF

FOR %%A IN (*.avi) DO CALL :avi2png "%%A"

:avi2png
ffmpeg.exe -y -i %* -sameq -f image2 -c:v png "%%~nA%%03d.png"

ECHO.
GOTO :EOF

I've tried both %~nA and %%~nA, but to no avail. The script returns this:

Code: Select all

Couldn't open file : 
av_interleaved_write_frame(): Input/output error.

I'm a complete layman and would welcome every bit of help.

There is no need to use a Call in this situation. Remove the call and put your ffmpeg code up with the for loop.

If you are going to use the call then your file name is in the %1 variable.
So if you want just the file name without the extension then you would use %~n1 to get the file name without the extension.

Thanks a million, Squashman! Works like a charm.
