• PHP-FFMpeg not converting (error with ffmpeg)

  13 août 2016, par Magurean Dan Sergiu

  I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

  But when I try to convert a video file with a php script it throws me a very long error.

  Unknown encoder 'libx264'

  My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

• Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ?

  20 juillet 2016, par hmj6jmh

  I am trying to swap the order of 2 audio tracks of an AVI file using ffmpeg.

  ffmpeg -i "infile.avi" -map 0:0 -map 0:2 -map 0:1 -c copy "outfile.avi"

  This works but the file is being re-encoded, not copied. It takes much longer than a straight copy to finish and the resulting file is larger than the original.

  Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ? Command line tool preferred.

• FFmpeg get frames equally spaced out from video

  2 décembre 2017, par TheOtherguyz4kj

  I am having some real problems with FFmpeg in my Android application. I am currently trying to take a video recorded from the device and extract frames from the video equally throughout the video. I used this blog post. The last formula :

  ffmpeg -i input.avi -f image2 -ss 2 -r 0.05 frame-%05d.png

  with my own -ss and own -r values.

  Now everything is fine. Like mentioned in the blog the first 2 frames are the same for some reason. So i delete one of the frames then I feel as though the frames accurately show the video. In the blog it also says to delete some of the last frames I dont do this because then i dont get frames going to the end of the whole video.

  In the output the first two images should be discarded and the next 6 images (from 3rd til 8th) will be the ones we were looking for. Most probably there’ll be a 9th image as well which can be discarded too. You can also add the -vframes 8 option (where 8 is number_of_frames + 2) to skip the creation of the last image that you won’t need anyway.

  How accurately are these frames captured ? Because I would like to add timestamps to each frame. (FFProbe is not an option because I am using an Android application and dont want to have to build the binaries just for this).

  If for example I had a video of 14 seconds long and ffmpeg extracted 11 frames (I remove one of the first duplicate ones, so now 10 frames). If i then did videoLength / number of frames * which frame I want to find how accurate would this be ? So :

  14/10 * 1 = 1 so frame one goes from 0s - 1.4s
  
  14/10 * 2 = 2.8 so frame two goes from 1.4s - 2.8s
  
  14/10 * 3 = 4.2 so frame two goes from 2.8s - 4.2s
  
  ...
  
  14/10 * 10 = 14 so frame two goes from 12.6s - 14s

  Would this accurate represent each frame ?

  If not could someonne give me a better solution please thanks.

  The idea is I have created a video cropper with a recyclerview so I will be able to "go over" each frame with a drag tool, calculate how much the frame has been covered and then find what range that frame represents and then set a time for the start and end crop times
