• How do I resize my video ? in proportion (python)

  23 septembre 2022, par ggn0

  *I am sorry for my poor English. It's a translator.

  


  I used Python moviepy to resize it, but the pixels are broken. I want to make the video 9:16 ratio while maintaining the original image quality. (So that there are black frames on both sides)

  


  from moviepy.editor import *
c = VideoFileClip('test.mp4')
f = c.resize(newsize=(1080,1920))
f.write_videofile('aa.mp4')


  


  This code causes pixels to collapse.

  


  Let me show you an example picture.

  


  Original Video Example

  


  The video I want

  


  Pictures that come out using movie resize (other example pictures, pixels collapse and proportions collapse) Pictures that I don't want

  


  It doesn't have to be moviepy, so I'd appreciate it if you could tell me how to use Python. (PIL ? opencv ?)

  


  Thank you so much. Have a nice day 🙏

  


• Using FFMPEG and PHP to encode HLS video on the fly

  21 avril 2024, par mrsmith

  I'm re-encoding a MP4 video to HLS using FFMPEG with PHP. I'm trying to then directly serve to the output to a HTML page's <video></video> tag. The following script (encode.php) encodes the video as I require and it works if I use the script url directly in VLC player for example but I'm struggling to get the gtml page to play it. The resulting video file should be compatible with most browsers. I use video.src = 'encode.php' on my player html page.

  


  Any help appreciated.

  


  <?php

$input_video = 'whatever.mp4';

// video passthrough
// hls format
// audio (english strems only) to aac (6 channel)
// output to stdout

$ffmpeg_command = 'ffmpeg -i ' . escapeshellarg($input_video) . ' -map 0:v -c:v copy -map 0:a:m:language:eng -c:a aac -ac 6 -b:a 320k -f hls -hls_time 30 -hls_list_size 120 -start_number 0 -';

$handle = popen($ffmpeg_command, 'rb');

header('Content-Type: application/vnd.apple.mpegurl');
header('Content-Disposition: inline; filename="output.m3u8"');

// stream the output to the browser
fpassthru($handle);
pclose($handle);
?>
