• ffmpeg conversion x264 [error] : malloc of size 769152 failed

  18 décembre 2014, par prashanthp

  I am trying to convert video recorded from Android smart watch (.mp4 format) to a format (.mp4) which playable on all browsers. The video recorded from smart watch is not playing in the browsers. so, i’ve used ffmpeg to convert in into a playable mp4 format.

  But sometimes it is showing error as x264 [error]: malloc of size 503008 failed

  What is the reason for this. Sometimes it’s getting converted and sometimes it is showing error .

  Here is the console output.

  When i execute this from shell it is working fine. But when i create a script file and trying to execute that script file from php , it is showing error’s. I increased the memory limit in php, still it is showing error. Also , we are using ZEND framework. Is there any problems with ZEND ??

• webM files shows green and purple effects on mobile

  11 octobre 2015, par Naveen Gamage

  I have converted several GIFs to webM files using ffmpeg on my Ubuntu 14.04 server.

  Heres the code I used for conversation.

  ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

  source https://gist.github.com/ndarville/10010916

  The problem is converted webM files shows perfectly fine on PCs but on my mobile it shows with green and purple shadows.

  PC

  

  Mobile

  

  I tried changing -crf and -b:v values to their max but nothing happens.

  webM file : http://d1pnsuxwa0it39.cloudfront.net/uploads/comments/webm/4673555.webm

  edit :

  also I can see webM files on some other sites fine. I think this has to do something with the way I convert files.

  edit :

  I have tried another code I found on stackoverflow but still the same.

  ffmpeg -f gif -i infile.gif outfile.mp4

  EDIT :

  If anyone think this has something to do with the way I installed FFMPEG, I followed the steps on FFMPEG official docs.

  https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

  Core : Exclude some keyboard keys to prevent revalidating the field
  Avoid revalidate the field when pressing one of the following keys
  
   in ’onkeyup’ method :
  
  	Shift       => 16
  
  	Alt         => 18
  
  	Caps lock   => 20
  
  	End         => 35
  
  	Home        => 36
  
  	Left arrow  => 37
  
  	Up arrow    => 38
  
  	Right arrow => 39
  
  	Down arrow  => 40
  
  	Insert      => 45
  
  	Num lock    => 144
  
  	AltGr key   => 225
  This helps especially with the remote method, which has a lot of
  
  overhead.
