• How to provide video streaming option for different formats on website

  3 avril 2014, par kami998

  In my website users can upload different video formats and i need to provide streaming for those formats (for example : mkv, avi, mp4, 3gp, wmv), but on web only mp4 format can be played by flash players.

  My videos are hosted on amazon s3 server while my webserver is on different location, what i do is receive stream from s3 and transmit to client, so what i need is to convert the video format to mp4 on the fly

  So, is there any possibility to perform this functionality ( i am using asp.net mvc webapi as streaming service )

  Any sort of help is appreciable...

• FFMPEG video encoded by android app doesn't scale properly on the website

  9 octobre 2016, par Ahmed Mujtaba

  I’m trying to creat e an app that records a video on phone and uploads it to the website. I’m using a FFMPEG library to encode the video to be streamed on the web. The command I’m using for encoding is below :

  -y i inputPath -vf scale=640:480,transpose=1 -strict experimental -s 360x640 -r 25 -vcodec mpeg4 -b 1000k ab 48000 -ac 2 -ar 22050 destinationPath

  The video is encoded fine but when I try to play it on the website, it’s stretched vertically and goes off the screen. I’m using html5 player to play it on the web. Here’s what the video looks like

  

  The video uploaded from the website is encoded using libx264 codec and it plays fine. However the library I’m using to encode on the android app doesn’t support libx264. I’m not sure if it’s the incorrect aspect ratio that’s messing up the playback or something else. I’ve set the aspet ratio to 640:480 but that hasn’t fixed things.
  Can anyone help ?

• How do I get ffmpeg to work on my website ?

  20 septembre 2023, par Sam Cordin

  ffmpeg works on my local computer when I provide the absolute path for it or make it work globally by editing the environment variables.

  


  But on my website it doesn't work at all. I uploaded ffmpeg.exe, ffplay.exe, and ffprobe.exe to public_html/

  


  Here is my code :

  


  <?php
  ini_set ('display_errors', 1);
  ini_set ('display_startup_errors', 1);
  error_reporting (E_ALL);
  $image1 = "/home/mywebsitename/public_html/uploads2/1.png";
  $image2 = "/home/mywebsitename/public_html/uploads2/2.png";
  $ffmpeg = "/home/mywebsitename/public_html/ffmpeg";
  $command = $ffmpeg." -i ".$image1." -vf scale=100:-2 ".$image2;
  system($command);
?>


  


  It's supposed to make one image file mimic another, while having some differences in size and quality.

  


  I enabled the system function in my php.ini file which allowed it to work, and it doesn't give me an error on that anymore.

  


  I also changed the permissions of all the files and folders involved(uploads2 folder, 1.png, 2.png, the ffmpeg programs) to 777 which allows everything from read, write and execute.

  


  However, nothing outputted, and the files stayed the same. How do I get ffmpeg to work on my website ?
