jpeg - php : How to create a string of image binary without saving it to a file? -


मेरे पास एक छवि वैरिएबल है, 

  $ im = imagecreatetruecolor (400, 300);   
 क्या जेपीजी प्रारूप में इस छवि के बाइनरी को एक फ़ाइल में सहेजे बिना पाने के लिए वैसे भी है? धन्यवाद!   
 
 
  ob_start (); imagejpeg ($ im); $ ImageString = ob_get_clean ();

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part.
