• FFmpeg skips generating thumbs

  25 janvier 2018, par Awais fiaz

  I am using ffmpeg for creating thumbs out of videos within php script however ffmpeg skips creating thumbs sometimes but sometimes it goes okay and works fine i am a little confused of this strange behavior.

  Command which fails :

  Command : /opt/bin/ffmpeg -ss 00:00:06 -i /home/my/public_html/files/conversion_queue/1516767375521d6.mp4 -an -r 1 -y -f image2 -vframes 1 /home/my/public_html/files/thumbs/2018/01/24/1516767375521d6-original-1.jpg 

  Output error

  [image2 @ 0x2eaab00] Could not open file : /home/my/public_html/files/thumbs/2018/01/24/1516767375521d6-original-1.jpg
  
  av_interleaved_write_frame(): Input/output error

  video:41kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown
  
  Conversion failed! 

  Command which works fine :

  Command : /opt/bin/ffmpeg -ss 00:01:01 -i /home/my/public_html/files/conversion_queue/1516867108c557e.mp4 -an -r 1 -y -f image2 -vframes 1 /home/my/public_html/files/thumbs/2018/01/25/1516867108c557e-original-1.jpg

  Output

  frame= 1 fps=0.0 q=3.1 Lsize=N/A time=00:00:01.00 bitrate=N/A speed=49.9x 
  
  video:21kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown

  Although both are same but still i am facing this issue.
  Any help regarding this would be really appreciated.

• GIF to MP4 Conversion with ffmpeg won't play in browsers or certain computers

  24 janvier 2014, par Gordnfreeman

  I am using a script to convert a gif to an mp4 file using ImageMagick and ffmpeg (the latest version from http://ffmpeg.gusari.org/static/). The conversion works and gives me a mp4 file which I can play on my home computer but not any other one, the file also does not play in browsers. I have downloaded a lot of codecs at home so I suspect that is the issue.

  The code I am using, I will include all of it incase there is a problem earlier on in the script :

  convert ORIGINALGIF.gif NEWPNG%03d.png
  
  ffmpeg -framerate 10 -i NEWPNG%03d.png NEWVIDEO.mp4

  And that is about it this script works and creates the file but I can only view it on my home computer, I did some research and found the script below :

  ffmpeg -framerate 10 -i NEWPNG%03d.png -b 1500k -vcodec libx264 -vpre slow -vpre baseline -g 30 NEWVID.mp4

  I have tried this and a few variations of it but even if the file gets made it cannot be played in any browsers.
