• can i speedup text watermarking on ffmpeg ?

  3 juin 2020, par Easy Tricks For Android

  This command i used ffmpeg -i "1.mp4" -vf "drawtext=text='watermak_name':x=w-tw-50:y=h-th-50:fontfile=/Windows/fonts/calibri.ttf:fontsize=20:fontcolor=white:shadowcolor=black:shadowx=2:shadowy=2" "output.mp4". watermark is working with this command, but it takes more time up-to 3 hours +

  



  this is the log i got from cmd

• FFmpeg 3.3.4 avfoundation to record only a specific section of the screen on macOS Sierra using the command line

  16 octobre 2017, par antedesk

  I’m using FFmpeg version 3.3.4 (installed via brew) through the command line to record my desktop during some automated tests on my macOS Sierra (10.12.6).

  I would like to record only a specific section of the screen but, unfortunately, I’m not able to find the proper options in the documentation to reach my goal.

  According to the FFmpeg documentation for avfoundation, this is the command I use :

  ffmpeg 
  
  -f avfoundation    // avfoundation
  
  -pix_fmt uyvy422   // pixel format
  
  -i 1               // input: desktop
  
  -r 30              // framerate for output
  
  [PATH]/test.mp4      // filename

  When I run this command I have the following output :

• FFMPEG avi to streaming mp4

  29 mai 2013, par Vprnl

  I'm trying to get ffmpeg to encode various AVI files to mp4 for streaming purposes but my inexperience with the subject matter is making me doubt I'll ever get this to work.

  I use this commandline :

  ffmpeg -i test.avi -vcodec libx264 -r 24 -ac 2 -acodec ac3 -ab 128k -bt 240k -preset    fast -strict -2 -b:v 320K -bufsize 62000 -maxrate 62000 -movflags frag_keyframe+empty_moov test.mp4

  I use the " -movflags frag_keyframe+empty_moov" to make it possible to serve a fragmented mp4

  And this is the log I get :

  I hope someone can point me in the right direction. The goal is to serve the file to a html5 player. But sadly that has not yet worked.
  Thanks !

  [EDIT]

  Sorry if I'm being unclear. I have two issues. First FFMPEG gives me an error (as you can see in the log) but I'm uncertain why I get this error and secondly, the stream does not actually work. The tanscoding starts, but the player never receives the video
