• PHP serving two different video files

  6 septembre 2016, par inan

  I’m currently serving with PHP .ts segments while FFmpeg is running.
  My idea was to show during the stream my own advert. So I decided to add between the .ts segments my own video file.

  The problem is, if the advertising file is not existing everything is working fine until the file for my advert exists. The script continues but is not showing the advert.

  I tried to serve just only the advert file and it’s working. So I can assume, everything with the file is alright.

  Is there a limitation, to serve just only one file extension or container etc ?

  I’m watching the streams with VLC and Enigma2

  A part of my code :

  while(streamIsRunning()){
  
  // Serving .ts segments
  
  while (!feof($file_handler) && ClientConnected($clientpid)) {
  
      $response = stream_get_line($file_handler, 4096);
  
      echo $response;
  
      flush();
  
  }
  
  
  
  // Serve Advert if exists
  
  if (file_exists($myAdvert)) {
  
      $file_handler = fopen($myAdvert, "rb") or exit ("Stream Not Working");
  
      while (!feof($file_handler) && ClientConnected($clientpid)) {
  
          $response = stream_get_line($file_handler, 4096);
  
          echo $response;
  
          flush();
  
     }
  
  }
  
  }

• ffmpeg - scrolling text with specified boundaries and cut video when text ends

  19 février 2017, par Elma Paul

  Having this working ffmpeg filter with overlayed scrolling text
  

  f -i text_bg.mp4 -vf "drawtext=enable:fontsize=200:fontcolor=White:fontfile='ARIALN.TTF':text='asdfhlajsdh LKFJAHSDFH':x=-(mod(8*n\,w+tw)-tw):y=h/2-th/2" outtt.mp4 -y

  I have two questions :
  1.) How can I set specified boundaries for drawtext ? Just fix positions where the text will dissapear. Like here in picture
  scrolling text with specified boundaries example
  2.) How is it possible to cut the video(specify time) according to the text length.Meaning that the video will finish after ends the text line +plus one second ?

• First image not showing image to video using ffmpeg

  3 octobre 2014, par death_relic0

  I am very new to ffmpeg and trying to convert a series of images to a video.

  The command I am using (copied/modified from a tutorial)

  ffmpeg -framerate 1/5 -start_number 1 -i dog%01d.jpg -c:v libx264 -r 30 -pix_fmt rgb24 dog.mp4

  Basically, I have 4 images labelled dog1.jpg, dog2.jpg, dog3.jpg and dog4.jpg.

  The problem is the output video I get has image starting at "dog2.jpg" and ending at "dog4.jpg" meaning that it is missing the first image in the sequence (i.e dog1.jpg).

  I tried with different image combinations and the same behavior happened, the resulting video never had the first image in the sequence.

  Any ideas ?
