  • ffmpeg command failed

    25 octobre 2015, par Asad kamran

    I am experimenting FFMPEG command to convert any video format to mp4.

    Server admin execute the below command created by me and show me the errors :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    This is error :

    [aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
    codecs are not enabled, add ’-strict -2’ if you want to use it.

    how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.

    my ffmpeg and server are as follow :

    ffmpeg version N-75903-g14573b9 Copyright (c) 2000-2015 the FFmpeg
    developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-16)

    EDIT 1 :
    I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :

    New command :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    After executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
    Its Log is as follow :

  • Running ffmpeg via PHP

    11 mars 2020, par FionaF

    So the end goal is to have a php script that, given a list of images, will automatically create a slideshow video with transitions and text overlays and maybe an audio track as well.

    I’m competent in coding PHP but not experienced in command line stuff.

    We have a dedicated server and I got hosting company to install ffmpeg for me.

    So I thought I’d start simple and slowly build up to ultimate goal. But I’m really struggling. I’ve spent a couple of days trying all sorts of things with very little success.

    I found this post with some excellent examples https://superuser.com/questions/833232/create-video-with-5-images-with-fadein-out-effect-in-ffmpeg but I can’t get any of them to work. Which makes me think that I’m doing something fundamentally wrong.

    So this does work for me - I get a nice little 30 sec video slideshow of 6 images displaying for 5 secs each :

    $ffmpeg="/usr/bin/ffmpeg";
    exec($ffmpeg.' -f concat -safe 0 -i input.txt -c:v libx264 -r 30 -pix_fmt yuv420p -y out.mp4 2>&1', $output);
    var_dump($output);

    and this is input.txt

    file /home/webvivre/public_html/videos/test/i1.jpg
    duration 5
    file /home/webvivre/public_html/videos/test/i2.jpg
    duration 5
    file /home/webvivre/public_html/videos/test/i3.jpg

    duration 5
    file /home/webvivre/public_html/videos/test/i6.jpg
    duration 5

    But this (basically taken from example in link above - have only changed image names and ffmpeg location) doesn’t work for me :

    $code="/usr/bin/ffmpeg -y -loop 1 -i i1.jpg -loop 1 -i i2.jpg -loop 1 -i i3.jpg -filter_complex \" [0:v]zoompan=z='min(zoom+0.0015,1.5)':d=125,trim=duration=5,blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))',setpts=PTS-STARTPTS[v0]; [1:v]zoompan=z='min(zoom+0.0015,1.5)':d=125,trim=duration=5,blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))',setpts=PTS-STARTPTS[v1]; [2:v]zoompan=z='min(zoom+0.0015,1.5)':d=125,trim=duration=5,blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))',setpts=PTS-STARTPTS[v2]; [v0][v1][v2] concat=n=3:v=1:a=0, format=yuv420p[v]\" -map '[v]' -c:v libx264 -pix_fmt yuvj420p -q:v 1 out.mp4 2>&1";
    exec($code,$output);
    var_dump($output);

    This is the output :
