Description

My cmd file:

dir/b/s *.mts >mtslist.txt
for /F "delims=;" %%F in (mtslist.txt) do ffmpeg.exe -n -i "%%F" -c:v mpeg4 -qscale:v 4 -vtag xvid -vf scale=1280:-1 -flags +qpel -acodec libmp3lame -ab 320k "%%~dF%%~pF%%~nF.avi"

Cmd window:

C:\Users\Właściciel\Documents\2014\_test>dir/b/s *.mts 1>mtslist.txt

C:\Users\Właściciel\Documents\2014\_test>for /F "delims=;" %F in (mtslist.txt) d
o ffmpeg.exe -n -i "%F" -c:v mpeg4 -qscale:v 4 -vtag xvid -vf scale=1280:-1 -fla
gs +qpel -acodec libmp3lame -ab 320k "%~dF%~pF%~nF.avi"

C:\Users\Właściciel\Documents\2014\_test>ffmpeg.exe -n -i "C:\Users\Właściciel\Documents\2014\_test\2014_06_14 15_39_44.mts" -c:v mpeg4 -qscale:v 4 -vtag xvid -vf scale=1280:-1 -flags +qpel -acodec libmp3lame -ab 320k "C:\Users\Właściciel\Documents\2014\_test\2014_06_14 15_39_44.avi"

The problem is a national character - when I copy dir _test to the root of the C - problem disapear and option -n work properly.

  • Summary changed from ffmpeg ignores -n option under cmd.exe to ffmpeg ignores -n when folder has a national char

Instead of a script, please provide the actual command line that does not behave as expected together with the complete, uncut console output and please test current FFmpeg git head to make this a valid ticket.

  • Reproduced by developer set
  • Status changed from new to open
  • Summary changed from ffmpeg ignores -n when folder has a national char to ffmpeg overwrites files with non-ascii characters on Windows (cmd)
  • Version changed from 2.0.4 to git-master

Running the following command several times overwrites the output file each time, this does not happen for an output file name like "out.png"
