Can't Batch Encode Wav Files

[MarioTainaka]

Hi there, it's little GUI is quite amazing. I do have one issue I can't encode wav files in batch. If I do ffmpeg errors saying it can't find the encoder and setting are wrong. But if you do the files on there own with the exact same settings they do encode.

Hi, thanks.
Can you post the script that it generates?

This happens on every file during converting

And this is the script keep in mind i'm just letting the GUI handle everything. if you do the files one by one it does work.

cd /d "C:\Users\sjomm\Desktop\StreamTool-master\mcoutput"

&& for %f in (*) do (echo)

&&

"C:\Users\sjomm\Desktop\FFMpeg Gui\ffmpeg\bin\ffmpeg.exe" -y

-i "C:\Users\sjomm\Desktop\StreamTool-master\mcoutput%~f"

-vn
-sn

I've released an update v1.7.9.4, let me know if it fixes it.

It looks like I needed to remove -b:a %A for wav. Leaving it blank lets PCM use the FFmpeg default, which I think is the max bit rate. You can still select the bit rate, bit depth, and sample rate manually if needed.

For reference, here's the script it generated that worked. I batch converted mp3 to wav.
(I'm using environment variable for FFmpeg so it just shows ffmpeg instead of the full path to the exe).

cd /d "C:\Users\Matt\Desktop\mp3\" 

&& for %f in (*) do (echo) 

&& 

ffmpeg -y 

-i "C:\Users\Matt\Desktop\mp3\%~f" 

-vn 
-sn 

-c:a pcm_s24le 
-map 0:a:0? 

-map_metadata 0 

-f wav 

-threads 7

It works flawlessly converted all 159 files without an issue.
