Thanks for your instant response. could you please explain how I can do this in background? Please explain with example code if possible.

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 am stuck in a task to change byteArray to Video in php. I am creating a webservice in php.

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

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

You are correct. It worked. Thanks alot

Hi, I have done some validations using javascript. It is working but form is still submitted even it returns false. I have used onclick="return function()" in html file. function isValidName(name,nameRegex) { if(!(name.match(nameRegex))) { alert("name can contains only alphabets"); //name.focus(); return false; } } //email format should match with the emailRegex function isValidEmail(email,emailRegex) { if(!email.match(emailRegex)) { alert("invalid email address"); //email.focus(); return false; } } //Password Length should be b/w 8 and 15 function isValidPassword(password,passRegex) { if(!password.match(passRegex)) { alert("Invalid password"); //password.focus(); return false; } } function checkInput() { // Stored values in variables var firstName=document.getElementById("firstName").value; var lastName=document.getElementById("lastName").value; var email=document.getElementById("email").value.toLowerCase(); var reEmail=document.getElementById("reEmail").value.toLowerCase(); var password=document.getElementById("password").value; var emailRegex=/^[a-zA-Z\_][\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/; var nameRegex=/^[a-zA-Z]+$/; var passRegex=/^[\w\-\@\#\&\*\%\$]{8,15}$/; isValidName(firstName,nameRegex); isValidName(lastName,nameRegex); isValidPassword(password,passRegex); isValidEmail(email,emailRegex); isValidEmail(reEmail,emailRegex); if(document.getElementById('gender').value=="") { alert("please select your gender"); document.getElementById('gender').focus(); return false; } return true; } Thanks in advance

Hello Everyone, I have created simple reg/login forms. I also provided option to user for updating his/her profile. When a user navigate to updation page, they get prefilled fields. But, password is not pre filled for security reasons. So, if a user update his profile without worrying about password, then password should not be updated. In my case, password blanked out in database. Thanks in advance.

Thanks alot pbs.
