ffmpeg does not draw text


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?


Solution

  • Combine all filters into a single graph, so

    -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
    

    becomes

    -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,scale=trunc(iw/2)*2:trunc(ih/2)*2
