  • How to convert large videos in aws using php and ffmpeg [on hold]

    14 novembre 2016, par Nick Lynch

    I would like to be able to convert mov and avi to MP4 using Amazon web services with php and elastic beanstalk.
    However if you try and convert a large video using ffmpeg the server will time out, and the video will not save. I want to know if there is a way to do this. Possibly involves splitting the larger video into small pieces and converting each of the pieces, then combining the pieces. However even this takes too long to actually do on the server.

    Any help you can give would be greatly appreciated.

    Thank you !

  • ffmpeg crashing for large "-filter_complex_script" inputs

    5 février 2016, par user1605871

    We’re experiencing an issue where ffmpeg seg faults for very large
    "-filter_complex_script" input files (roughly 3MB). The input file
    consists of a very large number of drawbox filters.
    The same processing pipeline works fine for smaller files, but seems
    to have an issue as the file size increases. Is there a hard limit to
    how large this file can be ? If so, is there a "magic number"
    somewhere that we can increase and re-compile from source ?

    Does anyone have any other thoughts or advice ?

    Thanks in advance !
