  • FFmpeg enable videotoolbox on iOS

    27 février 2016, par bigbangvn

    I build FFmpeg for iOS and have enabled VideoToolbox, but when decoding video use function avcodec_decode_video2, it doesn’t use VideoToolbox and very slow on iPhone.
    I use the example demuxing_decoding here : https://ffmpeg.org/doxygen/trunk/demuxing_decoding_8c-example.html
    and have try to setup VideoToolbox decoding without success.

    Have anyone encountered that problem ?

  • FFMPEG "Could not allocate memory" Errors through php

    10 décembre 2019, par Applepiee

    I’ve tried to find a solution online for days now but cannot find any solution.

    I just switched server (Intel Xeon to AMD) and since the switch I’ve not been able to get ffmpeg conversions working through the php script. ffmpeg was the exact same version and all php settings are set.

    All commands that the script executes (copied from log files) were tried in shell and executed with no problems.

    The errors look like this :

  • Blur a video based on timestamps using FFMPEG

    22 avril 2020, par Aeren singh

    I have a JSON file which contains location of human faces as well as their timestamp throughout the video.
I want to blur the video at multiple locations. My scenario is like there may be 3 faces at given time all 3 should be blurred, at times there may be no faces and hence no blurring will be needed.
