• 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.

  UPDATED

  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 ??

• Bad output from ffmpeg running on raw video from Wear OS device

  17 juin 2020, par lcj

  I am following these instructions regarding capturing and converting video from a Wear OS device, and I am running into problems. I get a video and I can tell it is my screen but it seems to be warped. This should be a green check with some white text.

  



  

  



  There is a lot of noise when I run this :

  



  ffmpeg -f rawvideo -vcodec rawvideo -s 400x400 -pix_fmt rgb24 -r 10 -i video.raw -an -c:v libx264 -pix_fmt yuv420p video.mp4
