  • sh : ffmpeg : command not found when run command through php

    21 septembre 2018, par Vivacity InfoTech

    I have installed successfully installed FFMpeg on root of my Centos 6 machine (https://trac.ffmpeg.org/wiki/CompilationGuide/Centos).

    My workplace of apache/php is /var/www/html

    Now I’m running below command successfully on /var/www/html directory to capture frame from the video file. It’s capturing a frame.

    [root@localhost html]# ffmpeg -i video.mpg -an -ss 30  -t 00:00:01 -r 1 -y -vcodec mjpeg -f mjpeg -s 160x100 frame8  2>&1

    I want to run this command through php and using shell_exec() or exec() php functions. My php code for running the command is :

    $cmd = "/root/bin/ffmpeg -i /project/app/webroot/videos/video.mpg -ss 00:00:14.435 -f image2 -vframes 1 /project/app/webroot/videothumbnails/example-thumb.jpg";
    
$locale = 'en_IN.UTF-8';
    
setlocale(LC_ALL, $locale);
    
putenv('LC_ALL='.$locale);
    
echo shell_exec($cmd);

    When I’m trying to run command through above php code, I’m getting below error :

    sh: ffmpeg: command not found

    Please help me to solve out this problem.

  • Yes or no, will ffmpeg api do hardware decoding on iOS ?

    15 janvier 2019, par Fattie

    There seems to be conflicting information on this.

    https://trac.ffmpeg.org/wiki/HWAccelIntro

    notice the first diagram, it firmly marks iOS as “Y” on VideoToolbox

    enter image description here

    however in the comments down the bottom it says

    VideoToolbox. ​VideoToolbox, only supported on macOS. H.264 decoding is available in FFmpeg/libavcodec.

    And in the confusing second diagram it says "Standalone" is not done for VideoToolbox.

    We have found that using ffmpeg compiled in to iOS .... it seems to not use hardware decoding, which is really a pain.

    1. With avcodec_get_hw_config() we get AV_PIX_FMT_VIDEOTOOLBOX, AV_HWDEVICE_TYPE_VIDEOTOOLBOX which is seemingly correct.

    2. But usage and framerates clearly shows everything is being done in CPU. The code is in ff_hevc_hls_residual_coding all the time. (That’s fffmpeg’s software decoder.)

    3. This very diff very long git.videolan.org URL here seems to suggest again it should all be working.

    4. Have tried every iPhone etc. of course
