ffmpeg sample code
Posted on 12. Jun, 2007 by Sajith M.R in Downloads, php source code
Install ffmpeg library in your server first.
Place a video file of any type on current directory (or anywhere), here it is clock.avi .
Click more for source code:
extension_loaded('ffmpeg') or die('Error in loading ffmpeg');
$ffmpegInstance = new ffmpeg_movie('clock.avi');
echo "getDuration: " . $ffmpegInstance->getDuration() .
"getFrameCount: " . $ffmpegInstance->getFrameCount() .
"getFrameRate: " . $ffmpegInstance->getFrameRate() .
"getFilename: " . $ffmpegInstance->getFilename() .
"getComment: " . $ffmpegInstance->getComment() .
"getTitle: " . $ffmpegInstance->getTitle() .
"getAuthor: " . $ffmpegInstance->getAuthor() .

"hasAudio: " . $ffmpegInstance->hasAudio();

I also can be used for file format conversion
Eg: exec(’ffmpeg -i ‘.$SourcePath.’ ‘.$Destination);
Here $SourcePath any file of any format , and destionation also another format.
eg: exec(’ffmpeg -i saji.3gp saji.flv’);

It seems as if you need to get a web host that has the ffmpeg library for php so that you can execute the ffmpeg commands with exec(). I found documentation of ffmpeg: http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html that helped out a lot. I assume that the exec() function requires parameters that can be found in the ffmpeg documentation such as:
exec(ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg)

Question I am trying to solve is this. We have flash based property tour tool that takes photos of property listings and displays them in sequence. Is there a way to take the swf that is displayed typically in a browser window and capture 30 seconds of it and convert to mpg using ffmpeg? Thanks in advance.

@Rohit
To work the uploading fast, do a queuing machanism for converting videos. See the implementation in mobshare.in
Register there and upload a pic, it wont come that time, instead a processing symbol will be shown. The real image will be displayed after a little bit time of processing

Hey
Any one tell me which is best bit rate in ffmpeg so videos will low in buffering in video player

@ Rohit…. `best` is such a subjective term. Low quality bitrates are less than 300k, but then your video will get pixelated. If you use the -sameq switch in your ffmpeg command, then the quality will be as high as the original, but then it could stream slowly depending upon your server, the bandwidth coming out of it, the bandwidth of your users, and their machine spec’s. I like 500k bitrates, personally.
@Sajith: Thanks for the function list. Now I can make my encoding engine smarter.

Hello Expert,
I am trying to convert into .flv file from other format.
i am using this command
$srcFile = “/home/amitadut/public_html/gallery_video/robot.avi”;
$destFile = “/home/amitadut/public_html/gallery_video/robot.flv”;
$ffmpegPath = “/usr/local/bin/ffmpeg”;
$flvtool2Path = “/usr/local/bin/flvtool2″;
// Create our FFMPEG-PHP class
$ffmpegObj = new ffmpeg_movie($srcFile);
// Save our needed variables
$srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
$srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
$srcFPS = $ffmpegObj->getFrameRate();
$srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
$srcAR = $ffmpegObj->getAudioSampleRate();
// Call our convert using exec()
exec($ffmpegPath . ” -i ” . $srcFile . ” -ar ” . $srcAR . ” -ab ” . $srcAB . ” -f flv -s ” . $srcWidth . “x” . $srcHeight . ” ” . $destFile . ” | ” . $flvtool2Path . ” -U stdin ” . $destFile);
But file is creating with 0 kb filesize.
can you tell me why 0 kb is creating??????????/
i have also print some propeties of ffmpeg for you

Hi Sajith,
New to use this FFmpeg. and to linux also.
I installed ffmpeg and trying to use the Library of the ffmpeg.
#include “libavcodec/avcodec.h”
#include “libavformat/avformat.h”
I am using simple sample code ,which takes vedio stream ,and convert it to someformat.
I am facing problem is when i wrote the C Code .
I complied it which is not the problem,but linking is getting problem.
It is giving like this
test.c:(.text+0xf6): undefined reference to `av_register_all’
test.c:(.text+0×12b): undefined reference to `av_open_input_file’
test.c:(.text+0×146): undefined reference to `av_find_stream_info’
test.c:(.text+0×183): undefined reference to `dump_format’

test.c:(.text+0×25f): undefined reference to `avcodec_alloc_frame’
test.c:(.text+0×294): undefined reference to `avpicture_get_………
Means it is unable to link with the contents of the header files ..
