ffmpeg in postprocessing fails on spaces in filename

[Druhl]

Hi all.

This problem seems like something others must have come across before but I can't find a single discussion of it here.

I have postprocessing.bat calling a ffmpeg copy but it errors out on a path / filename with spaces. I have the "%1" in quotes but I guess after the %1 is expanded out to the passed path and filename, the quotes are lost, and ffmpeg fails...

Logs attached as well as my postprocessing.bat. I don't even know if the rest of it works, I can't get past passing the input file yet.  haha

There's an example of the failure in nrecord.log at 2025-03-29 12:25:00.184

Thanks for any suggestions!

I don't support user scripts but I suggest the best thing to do is to look at the command line that NextPVR runs (it shows in the log)

Code:

C:\Users\Public\NPVR-data\scripts\PostProcessing.bat "X:\PVR\SPORTS\F1 Explained\F1 Explained Whats New In 2025_20250329_12151220.ts" 275 16458 43 "F1 Explained What's New In 2025"

and run that from the command line to see what the error is.

Thanks for the prompt reply.

From the command line ffmpeg reports the exact same error as what's in nrecord.log:

2025-03-29 12:25:00.184 [DEBUG][115] Starting: C:\Users\Public\NPVR-data\scripts\PostProcessing.bat "X:\PVR\SPORTS\F1 Explained\F1 Explained Whats New In 2025_20250329_12151220.ts" 275 16458 43 "F1 Explained What's New In 2025"
<snip ffmpeg version reporting etc>
2025-03-29 12:25:00.772 [DEBUG][131] > [in#0 @ 000002b04654fcc0] Error opening input: No such file or directory
2025-03-29 12:25:00.772 [DEBUG][131] > Error opening input file X:\PVR\SPORTS\F1.
2025-03-29 12:25:00.772 [DEBUG][131] > Error opening input files: No such file or directory

It's failing once it encounters the first space in the expanded path/filename, even though I have the "%1" in quotes in the ffmpeg command line (postprocessing.bat was attached):

"C:\Program Files\ffmpeg\bin\ffmpeg" -i "%1" -c copy -f mpegts %1-temp.ts >> "C:\Users\Public\NPVR-data\logs\postprocess.log"

Is there something else I need to or can do to fix this? I think in essence I just have to be able to pass %1 from nextpvr to ffmpeg while preserving quotes around the expanded/substituted filename.

Thanks

OK, but why are you putting %1 in quotes in the first place? It will already by quoted.
