Supporting all media types
13 avril 2011, parUnlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Audio & Video not synchronized properly if i merged more videos in mp4parser
1er octobre 2013, par maniyaI have used mp4parser for merging video with dynamic pause and record video capture for max 6 second recording. In preview its working fine when recorded video with minimum pause/record, If i tried with more than 3 pause/record mean the last video file not get merged properly with audio.At the start of the video the sync is ok but at the end the video hanged and audio playing in screen for the remaining file duration about 1sec.

Realtime ffmpeg shell output PHP
26 septembre 2013, par matthew johnstonAlright, I've been fighting this problem for a few days. Works fine on my local windows machine but, can't seem to get it to work on my CentOS server. My script grabs the duration of the video being converted and also grabs the current seconds it has processed inside of ffmpeg. However, it is only grabbing the "input file" of the ffmpeg output and stopping there. I have tried using both pipes (STDOUT [1] & STDERR [2]) for some reason ffmpeg likes to output on the STDERR pipe. Weird.
$filename = "somefilename.tmp";
$descriptor = array(
0 => array("pipe", "r"),
1 => array("pipe", "w"),
2 => array("pipe", "w")
);
$ffmpeg = "ffmpeg -i /var/www/spotloader/videos/flipped/tmp/".$file."_comb.ts -vcodec mpeg2video -acodec pcm_s16le -pix_fmt yuv422p -vtag xdvb -b:v 13000k -r 30000/1001 /var/www/spotloader/videos/flipped/tmp/".$file.".mov";
//open the process
$process = proc_open($ffmpeg, $descriptor, $pipes, NULL, $_ENV);
//if the process opened
if ( is_resource( $process ) == true )
{
//get process status
$procStatus = proc_get_status( $process );
//if its running, let node know
if ( $procStatus['running'] )
{
//nodejs socket, nothing wrong here
$this->_sendSocket('converting', array('filename' => str_replace('.tmp', '', $file)));
}
//while the process is running
while( $procStatus['running'] === true )
{
//there is output in the pipe
if ( !feof( $pipes[1] ) )
{
//get the output
$data = fgets($pipes[1], 128);
//match the outputs duration and save it.
if(preg_match('/Duration:\s([0-9]{2}:[0-9]{2}:[0-9]{2})/', $data, $matches))
{
static $duration;
$duration = $this->_convertToSeconds($matches[1]);
}
//match the outputs current encoding time
if(preg_match('/time=([0-9]{2}:[0-9]{2}:[0-9]{2})/', $data, $matches))
{
//convert to seconds works fine, so it is not included.
$curTime = $this->_convertToSeconds($matches[1]);
//nodejs socket, nothing wrong here
$this->_sendSocket('update', array('percent' => round( ($curTime / $duration) * 100), 'filename' => str_replace('.tmp', '', $file)));
}
}
//update process status
$procStatus = proc_get_status( $process );
}
//nodejs socket, nothing wrong here
$this->_sendSocket('converted', array('percent' => 100, 'filename' => str_replace('.tmp', '', $file)));

EDIT :
I got this to work using popen instead. It also reduced my code. If anyone else does have a solution go ahead and post it. Thanks ! -
Using FFmpeg's (libavformat) RTP data structures via dynamic linking
15 septembre 2011, par ericreevesI want to use the RTP data structures (e.g. RTPMuxContext in libavformat/rtpenc.h) provided by FFmpeg's libavformat however they don't seem to be available with the following install :

built on Sep 14 2011 16:04:33 with gcc 4.2.1 (Apple Inc. build 5666) (dot 3)

libavdevice 53. 3. 0 / 53. 3. 0
libavfilter 2. 40. 0 / 2. 40. 0
libswscale 2. 1. 0 / 2. 1. 0When I look in /usr/local/include, I see the libavformat directory however only a few files are there : avformat.h, avio.h, and version.h. Of course, when I try to include libavformat/rtpenc.h I get "error : libavformat/rtpenc.h : No such file or directory"
I'd like to achieve this by dynamic linking to the FFmpeg libraries (for LGPL compliance, among other reasons), but it doesn't seem to be possible.
Is there a parameter for the configure script that I'm missing, or a post-installation step that I've neglected ?
