ffmpeg not working with filenames that have whitespace

Question

I\'m using FFMPEG to measure the duration of videos stored in an Amazon S3 Bucket.

I\'ve read the FFMPEG docs, and they explicitly state that all whitespace and speci

Answer 1

As many have pointed out, the best option is to quote the string. It works for all other special characters. I am attaching a snapshot from Here are some examples I found of the ffmpeg documentation page. I am attaching a screen shot just in in case it is unavailable in the future.

Answer 2

I solved it by "enquoting" the arg that contain the file path. In my case, the path was stored in the %1 argument (which was written in the registry under quote that are escaped: \"%1\" ). I retrieve it (with a PowerShell script), simply using $arg (inbuilt argument). I then used it get some file information such as:

# Get the File path:  
$FilePath = $args

# Get the complete file name:
$file_name_complete = [System.IO.Path]::GetFileName("$FilePath")

# Get File Name Without Extension:
$fileNameOnly = [System.IO.Path]::GetFileNameWithoutExtension("$FilePath")

# Get the Extension:
$fileExtensionOnly = [System.IO.Path]::GetExtension("$FilePath")

Don't forget the quote around $FilePath.

Then you can use it to divide audio filesin 5min parts simply like this:

ffmpeg -i $file_name_complete -f segment -segment_time 300 -c copy $fileNameOnly"_"%03d$fileExtensionOnly #

Answer 3

ffmpeg uses % to define a pattern and handle multiple files. For instance if your filename is URI encoded you must use "-pattern_type none" to avoid misinterpretation from ffmpeg:

ffmpeg -pattern_type none -i file%20name.mp4

Answer 4

To make ffmeg works with filename/path that have whitespaces, you should:
1) set the working directory with Pushd
2) put your filename inside quote ""

here is a working example:

REM Cut an audio file by right-cliking it (works also on multiple selected audio)
REM 1) save this file
REM 2) open registry, browse to  Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SystemFileAssociations\audio\shell. On the left panel, right-click on "shell" and select "New", then "Key". Type "Cut audio 5min". Right click on the newly created folder "Cut audio 5min" and select again "New" and then "Key". Type “command”. On the right pane, double-click the "(default)" value name and type the following:  "C:\Users\Me\Cut audio.cmd" "%1"
REM  optional: if you want an Icon : in the left pane, right click  "Cut audio 5min", and select String value, then in the right pane, rename the new value to Icon, then double click on it and past this "%SystemRoot%\\System32\\shell32.dll,186"     (; list icon: https://diymediahome.org/windows-icons-reference-list-with-details-locations-images/ )

REM 3) right click an audio file and select "Cut audio 5min": the chunks will be created in the same folder. 

REM because ffmpeg has trouble with path/filename with space, we set the working directory to the folder of the audio file and the we run the command not on a full path but just on the filename, with "" around it

REM get https://stackoverflow.com/a/15568171/3154274

Answer 5

If you happen to have spaces in your file name, just quote them:

ffmpeg -i "my video file.mov"

In a URL, a space cannot be there. Most probably you have to replace every single space with a %20, so that you get:

ffmpeg -i http://myurl.com/my%20video%20file.mov

Answer 6

for fileOne in *.mp4
do
  baseName=$(basename "$fileOne" .mp4) # "$fileOne" quotes are necessary because of special chars in it
  echo "input: " $fileOne
  echo "var: " $baseName
  echo "target: " $baseName".mp3"
  cp "$fileOne" "tmp.mp4"
  # ffmpeg problem with specialchars like whitespaces and '-'
  # ffmpeg -i \"$fileOne\" "$baseName..mp3"
  ffmpeg -i "tmp.mp4" "tmp.mp3"
  mv "tmp.mp3" "$baseName".mp3""
done
rm "tmp-mp4"

`just rename the file for the conversion :)
