  • find xargs mac change filename extension

    27 janvier 2014, par brakertech

    I am trying to convert a directory full of mp3's (with spaces in file names) to m4a.

    To convert a single file (this works) :

    ffmpeg  -i Traffic.mp3 -c:a libfaac -vn Traffic.m4a

    The command that is failing (on OS X Mavericks) :

    find . -name \*.mp3 -print0 | xargs -0 ffmpeg -i {}  -c:a libfaac -vn {}.m4a

  • Convert from webm to gif using FFMPEG with minimal loss in quality

    27 novembre 2017, par Neo Herakles

    so I want to convert all my webm files to gif but the quality degraded incredibly, there’s some barely visible lines along the picture, tried using crf to improve it but it doesn’t, could you help me ? Here’s my code :

    @echo off
    
setlocal
    
for %%G in ("%~dp0\webm\*.webm") do (
    
    ffmpeg -i "%%G" -pix_fmt rgb24 -crf 17 "%%G.gif"
    
    )
    
)
    
endlocal
    
pause

    Also, could you instruct me in a way in which I can remove the .webm from the output filename ? it outputs as "(file name).webm.gif"
