can i speedup text watermarking on ffmpeg ?
3 juin 2020, par Easy Tricks For AndroidThis 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

Displaying the current frame of a video after skipping using drawtext/start_number not evaluation any variables
30 mars 2017, par DJ QuardaboffI 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 isThe 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 :
