I've written a php program which creates a video from sequence of images using ffmpeg.
<?php
$res = shell_exec("ffmpeg -framerate 50 -i image/image%d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4 2>&1");
echo "$res";
When I run it,
it says GLIBCXX_3.4.15
, GLIBCXX_3.4.9
, GLIBCXX_3.4.11
not found.
ffmpeg: /opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not
found (required by /usr/lib/i386-linux-gnu/libjack.so.0) ffmpeg:
/opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found
(required by /usr/lib/i386-linux-gnu/libzmq.so.3) ffmpeg:
/opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found
(required by /usr/lib/i386-linux-gnu/libopencv_core.so.2.4) ffmpeg:
/opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found
(required by /usr/lib/i386-linux-gnu/libopencv_core.so.2.4)
But from the terminal, ffmpeg -framerate 50 -i image/image%d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4
command works fine. Why php can't find the libraries while from the terminal it works fine? and what should I do to fix the problem in php? Thanks in advance.
