• 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

  

  

D :>ffmpeg -i "1.mp4" -vf "drawtext=text='watermak_name':x=w-tw-50:y=h/2-th:fontfile=/Windows/fonts/
  courbd.ttf:fontsize=20:fontcolor=white" -max_muxing_queue_size 9999 "1_out.mp4"

• Displaying the current frame of a video after skipping using drawtext/start_number not evaluation any variables

  30 mars 2017, par DJ Quardaboff

  I would like to display the current frame number on a video while playing it with ffplay. I have already seen this solution, but when I seek to any part of the video, the counter resets. There’s a variable, start_number, which the ffplay documentation says is The starting frame number for the n/frame_num variable. The default value is "0". It seems that n is set to that when starting the video or seeking between I-frames. I thought setting this variable to %{floor(t*60)} would solve my problem, but after running this :

  ffplay -i "video.mp4" -vf drawtext="fontsize=30:box=1:boxcolor=white:fontcolor=black:fontfile=/Windows/Fonts/arial.ttf:start_number=floor(t*60):text=%{n}"

  I got the following console output :

  In fact, any variable in start_number’s assignment invokes this error. I don’t know if I have the correct syntax, but does this mean it doesn’t evaluate expressions ? Or maybe it doesn’t accept variables for some reason ?

  After that downer I tried just setting the text to %{t}, which played the video, but repeatedly gave this error and had no text in the top left corner :

  [Parsed_drawtext_0 @ 0000000003e54ea0] %{t} is not known 0B f=0/0

  So does the current time variable just not work in drawtext ?
  Is there another way to write the current frame on the video or even on the console window ?

  Using Windows 10 Enterprise and the latest build of ffplay for windows at this time.
