• ffmpeg does not draw text

  4 septembre 2016, par Michael Heuberger

  hope one of you can tell me why this ffmpeg command of mine does not draw the desired text. the produced video doesn’t have it. here you go :

  ffmpeg -f image2 -thread_queue_size 64 -framerate 15.1 -i /home/michael-heuberger/binarykitchen/code/videomail.io/var/local/tmp/clients/videomail.io/11e6-723f-d0aa0bd0-aa9b-f7da27da678f/frames/%d.webp -y -an -vcodec libvpx -filter:v drawtext=fontfile=/home/michael-heuberger/binarykitchen/code/videomail.io/src/assets/fonts/Varela-Regular.ttf:text=www.videomail.io:fontsize=180:fontcolor=white:x=150:y=150:shadowcolor=black:shadowx=2:shadowy=2 -vf scale=trunc(iw/2)*2:trunc(ih/2)*2 -crf 12 -deadline realtime -cpu-used 4 -pix_fmt yuv420p -loglevel warning -movflags +faststart /home/michael-heuberger/binarykitchen/code/videomail.io/var/local/tmp/clients/videomail.io/11e6-723f-d0aa0bd0-aa9b-f7da27da678f/videomail_preview.webm

  the crucial part is this video filter :

  -filter:v drawtext=fontfile=/home/michael-heuberger/binarykitchen/code/videomail.io/src/assets/fonts/Varela-Regular.ttf:text=www.videomail.io:fontsize=180:fontcolor=white:x=150:y=150:shadowcolor=black:shadowx=2:shadowy=2

  does it seem correct to you ? if so, then why am i not seeing any text in the videomail_preview.webm video file ?

  using ffmpeg v2.8.6 here with —enable-libfreetype, —enable-libfontconfig and —enable-libfribidi enabled.

  furthermore, the above command has been produced with fluent-ffmpeg.

  so, any ideas ?

• Correct hindi text drawing when using ffmpeg

  28 février 2024, par OhhhThatVarun

  I have a ffmpeg script to add some Hindi text to the mp4 video file.

  


  The ffmpeg command looks like this

  


  ffmpeg -i template_video.mp4 -filter_complex "drawtext=text='नमस्कार जी मैं हूँ':fontfile=mukta.ttf:fontsize=40:box=1:boxcolor=black@0.5:boxborderw=5:x=530:y=530:enable='between(t,20,22)'[output]; [output] drawtext=text='आज हम स्कैन करेंगे':fontfile=mukta.ttf:fontsize=20:box=1:boxcolor=black@0.5:boxborderw=5:x=100:y=100:enable='between(t,15,20)'[outv]" -map "[outv]" -map 0:a? -c:a copy -pix_fmt yuv420p -s 1080x1920 output_video.mp4 -y


  


  Expected :

  


  

  


  Actual :

  


  

  


  

  


  As you can see the Hindi half letters are not getting rendered.

  


  I have gone through and tried these links :

  


  This question and This question

  


  I also tried this Github link

  


  Am I missing something to make it render properly ?

  


• Moviepy swap text mid video

  22 mai 2022, par Runeater DaWizKid

  I want to write text to a video and have it change mid playback, this is what I've tried but it overlays each text on eachother and only displays the text for 5 seconds ?

  


  def generateVideo(initial_text, secondary_text, tertiary_text):
    text_clip = TextClip(txt=initial_text, color='AntiqueWhite1', font='Arial-Bold', fontsize=100)
    text_clip = text_clip.set_position('center').set_duration(5)

    text_clip_secondary = TextClip(txt=secondary_text, color='AntiqueWhite1', font='Arial-Bold', fontsize=100)
    text_clip_secondary = text_clip_secondary.set_position('center').set_duration(10).cutout(0, 5)

    text_clip_tertiary = TextClip(txt=tertiary_text, color='AntiqueWhite1', font='Arial-Bold', fontsize=100)
    text_clip_tertiary = text_clip_tertiary.set_position('center').set_duration(15).cutout(0, 10)
    
    new_video = ColorClip(size=(1920, 1080), color=(0,0,0), duration=15)
    new_video.fps = 24
    
    new_video = CompositeVideoClip([new_video, text_clip, text_clip_secondary, text_clip_tertiary])

    new_video.write_videofile(codec='mpeg4', filename="test.mp4")
    new_video.close()


  


  Anyone see what im doing wrong ?

  


  Edit :
I've also tried the appropriate calls to subclip(pos1, pos2), ie

  


  text_clip_secondary = text_clip_secondary.set_position('center').set_duration(15).subclip(5, 10)


  


  With the same results
