MTranscodingProcess = new QProcess(this) Ĭonnect(mTranscodingProcess, SIGNAL(started()), this, SLOT(processStarted())) Ĭonnect(mTranscodingProcess,SIGNAL(readyReadStandardOutput()),this,SLOT(readyReadStandardOutput())) Ĭonnect(mTranscodingProcess, SIGNAL(finished(int)), this, SLOT(encodingFinished()))

Then, setup signals and slots in the constructor of FFmpeg dialog. The first step is to creating a QProcess object. The external executables such as ffmpeg.exe and ffplay.exe

In this example, we used QProcess on Windows 8. but at least the ffmpeg-php module is seen and appears to be built, so aside from my ffmpeg not working I'm guessing that process is sound.This tutorial's main focus is how to run external executable from Qt application. probably would be better to build ffmpeg from scratch instead of from an rpm distro.

Warning: dl() : Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20050922/ffmpeg.so' - /usr/lib/libavcodec.so.51: undefined symbol: av_free I had to change the extensions directory in my php.ini file to get the extension loaded, then I got the following errors from the test: #it seemed to ignore the -prefix directive #this installs ffmpeg and the devel pieces which ffmpeg-php wants to have, as well as any required dependancies. I'm going to do this on a test server in about an hour and I'll report back.ĮDIT: below are the results of my install: The better option, IF you're allowing runtime modules in your php.ini:įollow the 'Building as an Extension' instructions Use the configure option you copied earlier form the easyapache run, and append -with-ffmpeg=yes This should be the '/path/to/php_sources' referred to in the ffmpeg-php installation instructions

On the server, cd /home/cpapachebuild/buildapache/Ĭd to the PHP directory of the version in question. Whenever I have to do something to my php which the easyapache doesn't allow, I first run easyapache and watch for the PHP related configure lines. Under cpanel, you have to modify this as follows:
