• Possible bug in latest google chrome (v62) ?

  21 novembre 2017, par Jalal El-Shaer

  The following demo was working perfectly :

  http://jsfiddle.net/r6wz0nz6/2/

  The following is a sample of ’video-preview’ class in action :

  <a href="https://www.youtube.com/watch?v=v1uyQZNg2vE" target="_blank" class="video-preview" data-frames="100" data-source="http://i.imgur.com/BX0pV4J.jpg">
  
  </a>

  Now, if you use your mouse to scroll from left-to-right, somehow it is not working (shows thumbnail instead of current image position). This was working perfectly before v62. While, from right-to-left, it works normally.

  Updated Please watch how this looks here : https://www.youtube.com/watch?v=HvDP-YXJgOk

  Question : How can I overcome this bug/issue ?

  P.S. the demo is based on this blog post (https://www.binpress.com/tutorial/how-to-generate-video-previews-with-ffmpeg/138)

  Update 2
  Interesting, in the following part :

  elm.mousemove(function(e) {
  
  var left = e.clientX - elm.position().left;
  
  slider.show().css('left', left -1); // <<---------------------- this line
  
  img.css('left', -Math.floor((left / width) * frames) * width);

  if I remove the ’-1’ like so :
  slider.show().css('left', left);
  It works from Left-To-Right, but now from Right-To-Left is showing same bug !!

  Proposed Workaround by @A. Wollf
  Change the "mouseout" to "mouseleave" and it seems to fix it : http://jsfiddle.net/r6wz0nz6/388

• How do I add whitespaces when running ffmpeg from php shell_exec

  24 avril 2017, par Please Help

  I am trying to insert text overlay, and can do this, but I cannot add spaces to the text.

  ffmpeg -i meme.mp4 -y -vf drawtext='/Users/me/Library/Fonts/Champagne & Limousines.ttf:text='testtext': fontcolor=white: fontsize=24' -codec:a copy outputtexttest.mp4 2>&1

  The error when I make testtext test text is :

  Unable to find a suitable output format for ’text : fontcolor=white : fontsize=24’ text : fontcolor=white : fontsize=24 : Invalid argument

• Script to keep running ffmpeg always

  28 novembre 2022, par John Doe

  I have a raspberry connected to a network camera, recording an rtsp stream through ffmpeg.

  


  The problem is that the command stops for no apparent reason.

  


  I made a script to make it loop, but it also crashes...

  


  I have this script added in the rc.local so that it starts automatically.

  


  The sh script is as follows :

  


  while true; do FFREPORT=file"/home/pi/ffmpeglog_%p-%t.log":level=48 ffmpeg -hide_banner -y -loglevel error -rtsp_transport tcp -use_wallclock_as_timestamps 1 -i rtsp://xxxx:xxxx@192.168.1.108/11 -vcodec copy -acodec copy -f segment -reset_timestamps 1 -segment_time 3600 -segment_format mkv -segment_atclocktime 1 -strftime 1 /home/pi/Videos/camhi144_%Y_%m%d_%H%M.mkv; done

  


  Many thanks...

  


  I need to save the stream locally without it stopping...
