  • 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 :

  • Ffmpeg live streaming to Youtube - "Connect streaming software to start preview"

    Basically all looks good to me - still, in YouTube Studio only the waiting icon with the "Connect streaming software to start preview" message is visible, not video feed.

    Any ideas ?
