Please check server write permissions and/or available codecs compiled with FFmpeg. You can check the encode decode availability by inspecting the output array from PHPVideoToolkit::getFFmpegInfo().
i m trying to make it work since last many hours but no luck
Also, for this code :
$srcFile = "test-mpeg.mpg";
$ffmpegObj = new ffmpeg_movie($srcFile);
i am gettign error that it cant file the file. i believe its something to do with permissions but i m not able to figure out
fpoen , fwrite , file_put_contents all are working fine without any permissions problems.
can anyone please guide me in the write direction. what do i need to do to make this phpvideotoolkit work
