Hello, I have been working on a php webservice, which receives videos(uploaded) from iphone and upload them to Amazon cloudFront. After uploading videos, I need to generate thumbnails for video from the Amazon link generated. I am using ffmpeg with shell_exec command for it. Here is the code for the same: public function createThumbnail($userId,$fileUrl,$imageName){ //$imageUrl = 'http://184.168.116.177:81/json_api/json/bin/'; if(!is_dir("images/".$userId)){ mkdir("images/".$userId); } // path of installed ffmpeg $ffmpeg = $_SERVER['DOCUMENT_ROOT'] .'bin/ffmpeg'; $cmd = "$ffmpeg -itsoffset -1 -i $fileUrl -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 images/".$userId."/".$imageName; shell_exec($cmd); return "images/".$userId."/".$imageName; } The above code generates the thumbnail, but script does not execute after shell_exec command. So, there is no response sent to iphone end about the thumbnail link. This function works well video is uploaded from web browser of pc. If I comment, shell_exec command, then response is sent to iphone end, but obviousely image is not created. Thanks in advance.

Could you please explain with an example? Sorry for the late reply

Hello Everyone, I am doing a project where I am uploading user videos to amazon. On a page, user see titles of all the videos uploaded by him/her. These titles are clickable links(linked to amazon cloud). When clicked, it asks for "Open with" or "Save" in firefox. I want to play video in local player(which is available to user in his local machine) when link is clicked. I hope, it makes sense. Thanks in advance.

Hi Christian, I can email you the byte array file of a video, if you would like. File size is more than permissible limit. Please let me know your email address.

Hi Kicken, Thanks for your response. I already have tested with file_put_contents, but it does not seem to be working. I tried to convert a byte array file into video, but did not work. That is the file made by Iphone team from a video. I tried to convert it for testing purpose. So, if that file is not convertable, then data in post will not be converted, I think. Is there any difference b/w data in post or data in a file? I could not send you the file because it's size is 1 mb. I can email you if I can get your email id. Awaiting your response.

Hi Christian F. I had a discussion with my friend about it, who is working in .NET technology: Piyush: how do you convert byte array to video? Piyush: what are the steps involved? Shashank Awasthy: use the binary stream to read the byte array and then convert to video in C# Shashank Awasthy: made a file from stream Piyush: while writing to file, do you make any changes in encoding or write it as it is? Shashank Awasthy: i just provide the byte array to stream reader and then convert the stream to file Piyush: Ok Is this helpful in any way? I do not have any experience with it in php and also I have no knowledge of C#.

Hello Everyone, I have just started playing with cakephp. I baked one database and implemented registration functionality with validations. I wanted to implement login functionality, but could not achieve it. I have gone through the documentation many times but, no success. Can anyone send me link to the very simple tutorial? I have created login.ctp file in view and login function is defined in controller. I don't know what code should I write in that function and what addition/modifications are needed for model part. Thanks in advance

But, I could not understand the benefits of using objects inside objects. Could you please provide me a link where I can see any example? I have gone through the below link: http://www.tuxradar.com/practicalphp/6/6/0 But, it does not explain any benefit.

Hi Thorpe, Thanks for the response. I think, I have got it.

Hi, Thanks for the prompt reply. I am afraid, I am still unable to understand it completely. I could not understand "input" in $this->Form->input

Hello Everyone, I have just started working on cakephp framework. I have seen methods like $this->Form->input. I have not worked ever with such things. I can understand $this->variableName or $this->methodName. But what is meaning of "Form" there? Is this calling object of a class in other class? Thanks in advance
