I'm trying to create commands in a batch file where, if a certain nVidia file exists, it will encode a video using the graphics card - but if that nVidia file isn't there, it skips to another label to use another command.
This doesn't skip to the :SOFTWARE_ENCODE label if nvcuda.dll does not exist at the location:
if exist "%SYSTEMDRIVE%\Windows\System32\nvcuda.dll" goto :NVIDIA_ENCODE if not exist "%SYSTEMDRIVE%\Windows\System32\nvcuda.dll" goto :SOFTWARE_ENCODE If nvcuda.dll does exist then the above works and it skips to the :NVIDIA_ENCODE label.
I Googled around and saw someone solve it by using else with parentheses but that also doesn't work:
if exist "%SYSTEMDRIVE%\Windows\System32\nvcuda.dll" (goto NVIDIA_ENCODE) else goto SOFTWARE_ENCODE The same result happens, it seems to just skip the rest of the batch file if nvcuda.dll does not exist.
I know both nVidia encode and software encode work to encode the video because I have commented out the if exist and if not exist parts, testing each (ffmpeg) encode command individually.
(I'm renaming nvcuda.dll to ".bak" when testing the software encode).
I remember this happening in the past and have no idea why it ignores goto if used with if not exist.
Any solution is greatly appreciated.
EDIT: Here's the whole batch file...
