  I'm trying to use FFMPEG to transcode a video with very large frames but I'm getting the following error when trying to convert 4k video on my server.

• Ffmpeg is not always converting correctly

  11 juin 2016, par Lewis Day

  I’m having some problems when I’m using this command to convert video formats It sometimes works and sometimes it doesn’t. For .avi files it works for .3gpp only converts audio and for .flv it completely doesn’t work is there something that I’m doing wrong basically the $newfilename will only ever be video formats and the output format will always be a .mp4 Thankyou for any help

  ffmpeg -i /path/' . $newfilename . ' -vcodec copy -acodec copy /path/' . $rand . '.mp4'

  When I try and convert a .flv to .mp4 this is what is produces

• Turning images into videos with ffmpeg

  9 décembre 2014, par user3276588

  I asked this on another forum but never had any luck. I found the following command online that is supposed to create a video from images(duration of 5 seconds each) using FFmpeg.

  ffmpeg -f image2 -r 1/5 -i img%03d.png -vcodec libx264 out.mp4

  I have ran that and I have two images named img001.png and img002.png, however when I play out.mp4, it’s only a 5 second clip with img001.png being played. What’s really strange as well, is in my Windows Media Player, it thinks it’s 10 seconds long (2 images @ 10 seconds), but when the gauge gets half way through(5 seconds) the video, it ends.

  Any suggestions of what could be going on ?

  I also tried a bunch of other commands I found online but never had any luck. They would end up showing both images, but the first one would just flash for a fraction of a second, or some other ones would do the same thing would happen to the second image at the end of the video.

  I have it ImageMagick installed into XAMPP on my Windows Vista PC. I can provide my command line output from the command if needed.

  Edit : Added command line output

  C:\xampp\htdocs>ffmpeg -f image2 -r 1/5 -i img%03d.png -vcodec libx264 out.mp4
