ffmpeg.so in PHP exec converting and no return
13 juin 2015, par TomI have seen many threads, but none working ones, so this is my issue :
I have server installed ffmpeg (ffmpeg-php version 0.7.0, PHP Version 5.4.41) Linux CentOS 6 64bit :
Using PHP :
exec('/usr/lib64/php/modules/ffmpeg.so -i test.mp4 testdone.avi',$out,$ret);
or
exec('/usr/lib64/php/modules/ffmpeg.so -i /var/www/html/test.mp4 /var/www/html/testdone.avi',$out,$ret);
or
exec('/usr/lib64/php/modules/ffmpeg.so -i /var/www/html/test.mp4 /var/www/html/testdone.avi'.' 2>&1',$out,$ret);
the ffmpeg is actually found, but always returns :
array(0) { } int(11)
and with2>&1
returnsarray(0) { } int(139)
and does not return anything else liketestdone.avi in the directory or -version
(in the directory). Directories /var/www/html/ are set to 777.Thank you, should I hire someone to fix this or am I missing something in PHP.

Read H264 streaming from Elp H264 with OpenCV + Python
3 février 2017, par Francesco PaissanI’m trying to read an udp streaming of a H264 encoded image. The software structure is like follows :
On a BeagleBoneBlack (Ubuntu 16.04) I’ve an Elp H264 cam (see here : https://www.amazon.com/ELP-Support-Android-Windows-Surveillance/dp/B00VDSBH9G ). I stream frames with ffmpeg on a Unicast UDP Stream.
I want to read this images from python and opencv to be able to process them.
I tried with this simple code to see if the cap is opened or not :
import cv2
try:
cap = cv2.VideoCapture("udp://localhost:1234/")
cap.set(CV_CAP_PROP_FOURCC, CV_FOURCC('H', '2', '6', '4'));
except Exception, e:
print str(e)But when I run this script python says :
