• php ffmpeg cannot save video to system temporary folder

  28 mai 2024, par user2818066

  I am trying to covert a video to h.264 format. I can save the new video to a normal directory but saving the new video to a Windows temp file fails. However I can manage to save a snapshot image from the video into Windows temp folder without problem. I cannot figure out what is the problem ?

  


  require_once(dirname(__FILE__).'/../vendor/autoload.php');

function get_ffmpeg_exe_path_arr_def(){ 
  return( array( 'ffmpeg.binaries'  => "C:/bin/ffmpeg.exe",
                 'ffprobe.binaries' => "C:/bin/ffmpeg.exe",
                 'timeout' => 3600000000, 'ffmpeg.threads' => 12
                )   )  ;  
}

$vid_inp = 'C:/Users/Jordan/Downloads/motorboat_org.mp4' ; 
$vid_out = 'C:/Users/Jordan/Downloads/motorboat_9.mp4' ;
$tmp_vid_out_file = tempnam(sys_get_temp_dir(), "Vid") ; //C:\Windows\Temp\VidA318.tmp 
$tmp_img_file = tempnam(sys_get_temp_dir(), "Img") ; //C:\Windows\Temp\ImgA234.tmp


$ffmpeg = FFMpeg\FFMpeg::create( get_ffmpeg_exe_path_arr_def() );
$video = $ffmpeg->open($vid_inp);
$format = new FFMpeg\Format\Video\X264('aac', 'libx264');

$video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(0.2))->save($tmp_img_file);
// Ok to save snapshot image to  C:\Windows\Temp\ImgA234.tmp 

$video->save($format, $vid_out); 
// This is ok to save video to  C:/Users/Jordan/Downloads/motorboat_9.mp4

$video->save($format, $tmp_vid_out_file); 
// This fails to save new video to   C:\Windows\Temp\VidA318.tmp

• My ffmpeg library is not being recognised as in inter or external command when trying to convert a video in python [duplicate]

  22 avril 2024, par Shaahid Patel

  What im trying to do in python is to convert a 4k mkv video to 1080p mp4 video using the ffmpeg library.

  


  import subprocess

def convert_4k_to_1080p(input_file, output_file):
    cmd = f'ffmpeg -i "{input_file}" -crf 18 -c:v libx264 -c:a aac -s 1920x1080 "{output_file}"'
    subprocess.run(cmd, shell=True)


input_file = "c:/Users/Shaahid/Videos/Movies/Series/Arcane.S01E02.2021.2160p.UHD.WEB.AI.AV1.Opus.MULTi5-dAV1nci.mkv"
output_file = "c:/Users/Shaahid/Videos/Movies/Series/Test.mp4"
convert_4k_to_1080p(input_file, output_file)


  


  however i have been recieving the following error :
'ffmpeg' is not recognized as an internal or external command,
operable program or batch file.

  


  I was expecting my video to be converted from 4k to 1080p however I still get errors. I have tried deleted and re installing the library through pip but unfortunately the error still occurs. Im not sure what to do and can anyone kindly assist me

  


• ffmpeg : Unrecognized option 'alpha_quality'

  16 avril 2024, par László Monda

  I want to make transparent videos work in Safari, which doesn't support WebM for this purpose but only H265 with alpha transparency.

  


  According to this post, I used Shutter Encoder, but only some of its versions work for this purpose on Mac.

  


  Instead of using Shutter Encoder on Mac, I want to use ffmpeg on my Linux PC. Shutter Encoder uses the following command in the background :

  


  ffmpeg -threads 0 -hwaccel none -i input.mov -c:v hevc_videotoolbox -alpha_quality 1 -b:v 1000k -profile:v main -level 5.2 -map v:0 -an -pix_fmt yuva420p -sws_flags bicubic -tag:v hvc1 -metadata creation_time=2024-04-14T14:53:08.734684Z -y output.mp4

  


  which yields the following output on my PC :

Unrecognized option 'alpha_quality'.
Error splitting the argument list: Option not found


  


  When googling for "Unrecognized option 'alpha_quality'.", there are no results, which I find very odd.

  


  What's going on, and how can I make ffmpeg work for this purpose without Shutter Encoder ?
