• Packages are installed on server but not displaying in phpinfo()

  5 janvier 2012, par onkar

  I have installed imagemagick and ffmpeg on my CentOs 5.5 Godaddy VPS.

  I have added extension in php.ini also.

  I can able to see the installed packages in /usr/local/bin.

  But when I print phpinfo(), I am not able to see those. Not event I can use those packages.

  Any issue with installation ? any help on this ?

  Thanks, Onkar

• Range input breaks ffmpeg when seeking in Chromium

  14 janvier, par Tania Rascia

  I'm getting the following error erratically when I seek with the range input in a React app, which renders the input unusable until refresh :

  


  PIPELINE_ERROR_READ: FFmpegDemuxer: demuxer seek failed

  


  The only occurrence of this error I can find online is in the Chromium source code. <— linked file goes directly to the line where the error exists.

  &#xA;

  I can't replicate the error in Firefox.

  &#xA;

  


  &#xA;

  Nothing out of the ordinary is going on with the input.

  &#xA;

  const handleScrub = (event) => {
  const newTime = event.target.valueAsNumber

  setProgress(newTime)
  audioRef.current.currentTime = newTime
}


  &#xA;

  It happens if you click around really fast on the range. Here is an example of the source code, but the error doesn't happen with an .ogg file, only a signed .flac file.

• How to comp portion of first frame onto rest of video without re-encoding ? [closed]

  2 juillet, par jonathan

  I am working for a company recording educational screencasts using Goodnotes. The first frame looks fine, but as I work on the document, the page number pops up on the bottom left.

  &#xA;

  My bosses don't like this, so I've been trying to find a way to fix it on the screencast, since I can't find a way to turn it off in Goodnotes.

  &#xA;

  My current solution is taking a screenshot of the clean frame and using Gimp to crop out all but a small rectangle around where the page number would be, exporting that as a PNG and using ffmpeg to overlay that. The resulting image looks great and my bosses approve, but the script takes time to run since it needs to reencode. I'm wondering if there's a way to do this all with ffmpeg and run it with the -c copy flag since the first frame is clean. Please let me know if this is even possible.
