  background = mp.ColorClip(mobile_size, (255, 255, 255), duration=0.5) #float(audiolength.info.length)
text1 = mp.TextClip(english, fontsize=45, color=fcolor, font=Font, size= (mobile_size[0], 185), method = 'caption', align="south").set_duration(0.5) #float(audiolength.info.length)
text2 = mp.TextClip(formatChineseSentences(translated).encode("utf-8"), fontsize=45, color=fcolor2, font=Font, size= (mobile_size[0], 185), method = 'caption', align="north").set_duration(0.5) #float(audiolength.info.length)

clip1 = mp.CompositeVideoClip([background, text1.set_position(('center', "top")), text2.set_position(('center', "bottom"))])

• Issue with image using ffmpeg to combining it on PHP

  8 mai 2017, par 7sega7

  I’m trying to combine images with ffmpeg on PHP.

  First, I save the image with this and resizing then :

  $imagen = file_get_contents($_SESSION['img']);
  
  file_put_contents('img_prod.jpg', $imagen);
  
  $img = resize_imagejpg('img_prod.jpg', 650,360);
  
  imagejpeg($img, 'img_prod.jpg');

  Then I create a png with only a title or info. At the moment I’m giving the text with a form, later I’ll do with BD.
  For this I’m using the imagettftext :

  titulo = explode("-", $_SESSION['title']);
  
  $im = imagecreatetruecolor(400, 30);
  
  $white= imagecolorallocate($im, 255, 255, 255);
  
  $black= imagecolorallocate($im, 0, 0, 0);
  
  imagefilledrectangle($im, 0, 0, 399, 29, $white);
  
  $font= 'Comfortaa.ttf';
  
  imagettftext($im, 10, 0, 15, 10, $black, $font, $titulo[$i]);
  
  imagepng($im, "img_con_texto.png");
  
  imagedestroy($im);

  What I’m doing here is, first I get the Title for my form, and with the explode, every time I read a "-", I put all the text in another line. I simplified this on the code quote por easy read.
  Then I create the color, I filled the all rectangle with one color, pick the font and put the font, color font and the text on a image and destroy the variable for using again with another text.

  At the end, I use ffmpeg to put the image for "file_get_contents" and the image with the text.

  echo shell_exec('ffmpeg -y -i marco.png -i img_prod.jpg -filter_complex "overlay=20:(main_h-overlay_h)/2" out_img_prod.jpg')

  The "marco.png" it is just a white image with no contents. I open paint, change the resize pixels for 850/480 and saving that as marco.png.

  Then I add the text on the right side with the last image :

  echo shell_exec('ffmpeg -y -i out_img_prod.jpg -i img_con_texto.png -filter_complex "overlay=500:140" prod_title.jpg');

  The issue is that, when I do this, the text have a light gray color on the background. When I create the img with the text, It have white background color and it is a .png So I don’t know why It have that gray background color.
  This is the image from the last code :

  If I did the same with paint or gimp, adding mannualy the text on the image on the left, the background gray color dissapear so, It is possible to quit that light grey color ?

  PD : I quit some code for a simple read, so maybe I miss to quit variables. Also, If the img is more smaller and the text don’t collide with the text, the light gray color still there.
