• video after ffmpeg command conversion is not playing on windows

  10 décembre 2015, par Hemant Kumar

  I am stuck at a very weird and complex problem, hoping if anyone know the solution :

  I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it’s screen either show loading icon or black screen while audio is working fine.

  I am using following codec :

  ['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']

  I work on linux and using html5 player on my website. I am converting video in mp4 format.

  Input :

  ffmpeg -i /<server path="path">/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path="path">/testing.mp4
  
  </server></server>

• ffmpeg command not working with Windows XP when files have spaces

  25 février 2014, par user1665130

  I have a wpf application program for video audio merging using a command line tool ffmpeg.
  I can successfully merge files in Windows 7. But when I try to run my program on Windows XP it shows errors.

  Here I include my command line code.

   ffmpeg -i C:\Users\vishnu.aravind\Desktop\SUNP.AVI -i C:\Users\vishnu.aravind\Desktop\Alarm03.wav -c:v copy -c:a aac -strict experimental C:\Users\vishnu.aravind\Desktop\ Vishnu Aravind\new.avi

  I made some research on this and i find out that if the input filenames and output filenames contain extra spaces in them, normally ffmpeg won't take it. Suppose if I edit my above code to

   ffmpeg -i C:\Users\vishnu.aravind\Desktop\SUNP.AVI -i C:\Users\vishnu.aravind\Desktop\Alarm03.wav -c:v copy -c:a aac -strict experimental C:\Users\vishnu.aravind\Desktop\VishnuAravind\new.avi 

  this will successfully execute.

  How to solve if I want the output to be saved to a folder whose folder name contains an extra space ?
