Reading colors encoded in image at a position changes its value after decoded from video using php and ffmpeg
29 novembre 2022, par Jeenus JunanioI created a piece of code to encode unique color on image and converted the image to PNG so that it would be lossless. After This I created a video with the frame using this image using the ffmpeg in php shellexec(). After saving this video I reopened it to extract the frmae image added and tried to read those values from the image. Now the values on the image are a bit changed.


Here is the code that I tried to create the video :


$canvas = imagecreatefromjpeg('translate/first_frame.jpg');
 // create a random color
 $rand = str_pad(dechex(rand(0x000000, 0xFFFFFF)), 6, 0, STR_PAD_LEFT);
 $dec_color= hexdec($rand);

 // add the new color to image

 for ($i=0; $i < 24; $i++) { 
 imagesetpixel($canvas,$i,0,$dec_color);
 }

 // store the image and close the file opened

 // $filename = 'translate/test/output.png'; 
 $filename = 'translate/test/output.bmp'; 

 // imagepng($canvas, $filename);
 imagebmp($canvas, $filename);

 imagedestroy($canvas);

 $frame = $filename; // an image(png,gif,etc)
 $audio = 'translate/output/audio/abcdefghijklmnopqrstuvwxya.mp3';
 $output = 'translate/output/video/'.time().'.mp4'; 

 $cmd = 'ffmpeg -loop 1 -y -i '.$frame.' -i '.$audio.' -c:v libx264 -tune stillimage -c:a copy -shortest '.$output;
 shell_exec($cmd);


This above code is creating the video with the image.


Now I tried to extract the image video and color from image, the colors are a bit changed.


if($request->hasFile('video')){
 $file = $request->file('video');
 $filename = $file->getClientOriginalName();
 $path = public_path('translate/test/');
 }else{
 return 'No file uploaded';
 }
 
 
 if ($file->move($path, $filename)) {
 $video = 'translate/test/'.$filename;
 }else{
 return 'error file upload';
 }

 
 // $output = 'translate/output/image/'.time().'.png';
 $output = 'translate/output/image/'.time().'.bmp';
 // $output = 'translate/output/image/'.time().'.jpg';

 $cmd = 'ffmpeg -i '.$video.' -vframes 1 '.$output;
 shell_exec($cmd);


// $dimg = imagecreatefrompng($output);
 $dimg = imageCreateFromBmp($output);
 // $dimg = imagecreatefromjpeg($output);

 $extracted_color = array();

 for ($x=0; $x < 24 ; $x++) { 
 $extracted_color[]= imagecolorat($dimg, $x, 0);
 }

 echo "<br />Retrived colors:<pre>".print_r($extracted_color,1)."</pre>";

 imagedestroy($dimg);





The color added was 44743072 but the colors retrieved are 4539914,4474121,4408072,4408326 from x=0,y=0 to x=24,y=0.


In both PNG and BMP I am loosing the added pixels. You can clearly see in my code i have commented the code for png to read the image as bmp.


Can someone let me know if I miss anything here.

How do I use ffmpeg to bulk scale videos of different sizes to the same size (some potentially with black bar padding) ?
9 décembre 2020, par Tumbleweed53I have a bunch of videos I want to stitch together. I want to scale them all to the same size, maintaining aspect ratio (thus adding black bar padding if necessary). Some videos will be downscaled, but most upscaled.


Does anyone have a clever ffmpeg scale formula to accomplish this ? My alternative is to iterate through every video and calculate the scale formula based on its size, but I'd prefer not to do that if I don't have to.
