• ffmpeg is not working while uploading file using uploadify

  21 janvier 2016, par Ranjith

  for a particular video i tried like this, and it worked

  exec('/usr/bin/ffmpeg -i /home/xxxxxx/public_html/test/video1.mp4  /home/xxxxxxx/public_html/test/video1.flv');

  but for uploadify i write code like this ,

  <?php
  
  
  
  if (!empty($_FILES)) {
  
  $userId=$_SESSION["user_userid"];
  
  $filename = $_FILES['Filedata']['name'];
  
  $filetmpname = $_FILES['Filedata']['tmp_name'];
  
  $fileType = $_FILES["Filedata"]["type"];
  
  $fileSizeMB = ($_FILES["Filedata"]["size"] / 1024 / 1024);
  
  $folder=$_REQUEST['folder'];
  
  
  
  exec("/usr/bin/ffmpeg -i"."/home/xxxxxx/public_html/private/".$folder."/".$filename." "."/home/xxxxxx/public_html/private/".$folder."/".$filename.".flv");
  
  
  
  }elseif($_POST['d']){
  
  $filename = $_POST['d'];
  
  $folder=$_REQUEST['folder'];
  
  $dFile = $folder.$filename;
  
  if(file_exists($dFile)){
  
      unlink($dFile);
  
  }
  
  }
  
  ?>

  this code is not converting the uploaded file.
  help me please.

  thanks

• Is "begin" param dead in Youtube's *.c.youtube.com/videoplayback ?

  23 janvier 2013, par Minime

  I tested Youtube video download with begin param using ytdl, and realized that it's not working properly. Below is an URL with begin param. (It won't work on your side because it's session-IP address based.)

  http://r4---sn-o097znee.c.youtube.com/videoplayback?ratebypass=yes&cp=U0hUTVNOT19JTENONF9LSFNIOmtjaWozaFd5Vnhl&newshard=yes&source=youtube&ipbits=8&fexp=916600%2C906072%2C923114%2C914093%2C916626%2C920704%2C912806%2C922403%2C922405%2C929901%2C913605%2C925710%2C929104%2C929110%2C908493%2C920201%2C913302%2C919009%2C911116%2C926403%2C910221%2C901451&id=58dafac107cd7cae&key=yt1&mt=1358307193&gcr=us&ms=au&itag=46&upn=efQT2cDue5M&ip=xxxx&sparams=cp%2Cgcr%2Cid%2Cip%2Cipbits%2Citag%2Cratebypass%2Csource%2Cupn%2Cexpire&expire=1358331742&sver=3&mv=m&signature=C957313FEC2AC174F72CEFE52BF663ABAC8D0E4B.27F8485A36BE654CA25D3CA75A927D443523CA68&begin=12000

  I traced Youtube site by myself to see if there are any recent changes on their black boxed
  API. And I found that begin param is no longer put in videoplayback, but put in user_watch as below.

  http://www.youtube.com/user_watch?video_id=-YFiHW59ASs&ptk=StyleHaul&referrer=None&t=vjVQa1PpcFPiDK6v9s-rWrDn8gNv0QvpjyCIjiAgsm0=&asv=3&fmt=34&cpn=BOOMP-Bzbv1jikj9&el=detailpage&plid=AATTaqGSIR9CQ-MJ&begin=70000

  Its response is

  <?xml version="1.0" encoding="utf-8"?>

  And videoplayback only has range param, which indicate byte range where to pull. However, I couldn't figure out exact mechanism how new begin param works.

  Can anyone explain how to pull a video starting from specific position(msec) in new API ?

• Facebook Live Stream API on iOS

  11 août 2020, par Deepak Sharma

  I see Facebook has a graph API to go live on Facebook, fetch all user reactions, create a poll, etc. But I don't see any sample code in the SDK for the same. I want to stream video from iOS/Android app to Facebook.

  


  


  1. Is it sufficient to use ffmpeg based libraries on iOS to create live RTMPS stream on Facebook or a third party cloud service is required ? Any sample code that has the Facebook live function builtin ?

     


  


  2. What does the live video API review involves ? Anyone familiar with common causes of rejection for the live video API ?
