php ming flash slideshow to mp4/avi
19 août 2013, par StefanAfter hours of searching and trying i finally got a nice script together that generates a good looking Flash .swf file with a nice transaction in between de images.
It works great if you access the swf file directly in a browser, depending on the amount of images the flash created takes anywhere between 10 and 60 seconds.
But when uploading to Youtube the movie created flashed by in one second.
Because swf isnt really a accepted fileformat for Youtube we decided to convert the flash file to mp4 or avi using ffmpeg.
Unfortunally that didnt work, it had the same effect as the youtube movie.
We had a old version of ffmpeg and updated that to a recent version and tried to convert again with the same result.
The main thing i see is that ffmpeg cant see the swf file duration and bitrate, they are both 'N/A' while were do set them in the php script.Now i have to admit i havent really tested with the new version because the commandline options are a little different but ill work on that after i post this.
In the previous version we tried setting the framerate of the source swf file, but that didnt work either.Anyone here that can has a idea ? it would be greatly appriciated.
PHP Ming Script :
$fps = 30;
foreach($objects as $objectId => $images){
// START FLASH MOVIE
$m = new SWFMovie();
$m->setDimension($width, $height);
$m->setBackground(0, 0, 0);
$m->setRate($fps);
$m->setFrames(count($images)*202); //count(images)* 2 breaks *($fps*$breakTime)+22(fadeOut))
$i = 0;
foreach($images as $image){
// REMOVE THE BACKGROUND IMAGE
if($behind){
$m->remove($behind);
}
// # REMOVE
// LOAD NEW IMAGE
$img = new SWFBitmap(fopen($image,"rb"));
$pic = $m->add($img);
$pic->setdepth(3);
// # LOAD
// BREAK TIME
for($j=1;$j<=($fps*$breakTime);$j++){
$m->nextFrame();
}
$m->remove($pic);
// # BREAK
// LOAD THE NEXT IMAGE AS BACKGROUND, IF LAST IMAGE, LOAD FIRST
$nextBackgrondImage =($images[$i+1]) ? $images[$i+1] : $images[0] ;
$img = new SWFBitmap(fopen($nextBackgrondImage,"rb"));
$behind = $m->add($img);
$behind->setdepth(2);
// # LOAD
// AND FADE OUT AGAIN
$img = fadeOut($image, $width, $height);
$pic = $m->add($img);
$pic->setdepth(3);
// # FADE OUT
// BREAK TIME
for($j=1;$j<=($fps*$breakTime);$j++){
$m->nextFrame();
}
$m->remove($pic);
# BREAK
$i++;
}
$m->save('./flash/'.$nvmId.'_'.$objectId.'.swf');
unset($m);
}

GStreamer x264 on Linux (ARM)
8 septembre 2017, par Tõnu SamuelTrying to get streaming work with x264 encoding.
I am doing some black magic with stitching two images which is known to work :
gst-launch-1.0 -e \
v4l2src device=/dev/video0 ! \
video/x-raw,framerate=90/1,width=640,height=480 ! m.sink_0 \
v4l2src device=/dev/video1 ! \
video/x-raw,framerate=90/1,width=640,height=480 ! m.sink_1 \
videomixer name=m sink_1::xpos=640 ! \
video/x-raw,framerate=90/1,width=1280,height=480 ! \
xvimagesinkNow I am trying to get same thing over x264 stream with help of internet :
gst-launch-1.0 -e \
v4l2src device=/dev/video0 ! \
video/x-raw,framerate=90/1,width=640,height=480 ! m.sink_0 \
v4l2src device=/dev/video1 ! \

h264parse config-interval=1 ! \
rtph264pay ! \
udpsink host=127.0.0.1 port=5000And seems to work because no errors appear. But I see no way to receive image.
I have tried
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp ! rtph264depay ! h264parse ! avdec_h264 ! xvimagesinkwhich does not provide anything useful. Also attempted to use VLC with SDP file :
c=IN IP4 127.0.0.1
m=video 5000 RTP/AVP 96
a=rtpmap:96 H264/3000I must be doing something wrong but unsure what.

FFMpeg + Beanstalk : How to pass the processes to it
14 juillet 2012, par Ilia RostovtsevI'm working around on the video web site ! I have a simple PHP function that is used to start complicated conversion processes. The problem is that FFMpeg and Mencoder are extremely resourceful and having one process of it is something that makes httpd slow down but multiple processes just hang it completely. I want to my conversion processes with Beanstalk (or anything else). Everything is working well right now : converting, logging and etc.
My concrete question is : How to transfer my current jobs to Beanstalk ?
I have very simple PHP code :
RunInBackground('convert.php', array($initial_file_name, $vid), $LogFilePath);And the function looks also quite clear :
function RunInBackground($sPHPFile, $aParam = array(), $sLogFile = '')
{
global $config;
$sCmd = $config['phppath'] . ' ' . $config['BASE_DIR'] . '/' . $sPHPFile;
foreach ($aParam as $s)
{
$sCmd .= ' ' . $s;
}
$sCmd .= ' > ' . ($sLogFile != '' ? $config['BASE_DIR'] . '/' . $sLogFile : '/dev/null');
if ( iBgProc($sCmd) )
{
return true;
}
else
{
return false;
}
}
function iBgProc($sCmd, $iPrio = 0)
{
if ($iPrio)
{
$iPID = shell_exec("nohup nice -n $iPrio $sCmd 2> /dev/null & echo $!");
}
else
{
$iPID = shell_exec("nohup $sCmd 2> /dev/null & echo $!");
}
return($iPID);
}Now what would Beanstalk correct code would look like so these processes would NOT start all at the same time if multiple videos are uploaded ?
If you believe that for my needs is better to use something else but Beanstalk and you know how to implement it, I would be still happy to see it !
Thanks !
