• preventing playing video files outside the app/website

  5 octobre 2019, par hretic

  i feel the down votes are coming ! but im desperate so here it goes

  i have bunch of videos that i want my users to be able to play them only trough my mobile app or website(not sure about the platform) ... even when they’re downloaded on the client side

  i’ve never worked with video files before but i have lots of coding expense and know multiple languages (js , php , python , node , .... )

  but i done know where to begin , im not looking for code ... just someone with experience in this area to point me to the right direction and maybe give me some links to read about the subject and what technologies i need to get familiar with

  i tried to search around but most results are about html5 player or desktop video players

  i was thinking maybe i can encode mp4 files so they wouldn’t play with available players and then create a custom video player to decode and show them ?

  any suggestion would be appreciated

• How to specifiy ffmpeg creation time as the segment creation time

  6 novembre 2023, par şahin

  I am using ffmpeg to create video records from streams. Ffmpeg command creates segments from the streams. Think that 24 hours record with ffmpeg and divide it into 1 hour segments so i have 24 video records at the end. Problem is that ffmpeg always put the first segment creation time to the following ones meta data. Last video has the first video creation time. How to create segments with the time they created ?

  


  My ffmpeg commands

  


  ffmpeg -y -buffer_size 500000 -thread_queue_size 128 -i $1 -metadata title=$2 -metadata creation_time="`date +%F` `date +%T`" -c:a copy -c:v copy -f segment -segment_time 01:00:00 segment_format mp4


  


• How to justify text in drawtext in ffmpeg ?

  26 décembre 2019, par Milan Tejani

  I am adding text watermarks to the video using ffmpeg command and I’ve added three lines already using drawtext in ffmpeg command. So, it works perfectly and adds three lines at the bottom left corner of the video.

  In the first line there are 25 characters, the second line contains 7 characters, and the third line contains 3 characters. These three lines are located from the left to right.

  So, I want to justify 2nd and 3rd line’s texts to the center as per the first line width.

  What I get :

  Hello World Ffmpeg
  
  
  
  hello
  
  
  
  hel

  what I want :

  Hello World Ffmpeg
  
  
  
        hello
  
  
  
         hel

  here command i used :

  ffmpeg -i input.mp4 -vf "[in]drawtext=fontsize=20:fontcolor=White:fontfile='roboto.ttf':text='Hello World Ffmpeg':x=(w)/2:y=(h)/2, drawtext=fontsize=20:fontcolor=White:fontfile='roboto.ttf':text='hello':x=(w)/2:y=((h)/2)+25, drawtext=fontsize=20:fontcolor=White:fontfile='roboto.ttf':text='hel':x=(w)/2:y=((h)/2)+50[out]" -y test_out.mp4
