• Android Java (ffmpeg-kit). Assistance(opinion) with combining 4 ffmpeg commands together

  26 novembre 2022, par D-MAN

  I have the following 4 ffmpeg commands. 1. adds a png frame(border) over the entire length of the video. 2. creates a boomerang effect. 3. adds an outro jpeg to the last 2 seconds of the video. 4. Adds an intro jpeg to the first 2 seconds of the video.(these commands work individually)

  


  My aim is to combine all of these individual commands into one command to create a complete edited video. The final video needs all these elements in one final edited video.

  


  Your assistance is greatly appreciated.

  Being new to ffmpeg, I am limited in knowledge. However, I have tried '&&' which produced an unrecognized error from the ffmpeg library.

  


• FFMPEG -filter_complex drawtext with style like bold italic and underline

  6 janvier 2019, par Mubbashar

  I am trying to add text on padded area of my video. There are 4 to 5 things that i am not able to do

  • 1) Draw text styling (bold, italic, underline)
  • 2) Padded area opacity
  • 3) Subtitle vertical alignment. When i give some value to VAlign it
    sometimes goes out of the window. how to calculate correctly like
    50px from top or let say 200px from bottom
  • 4) The subtitle should be full width to video. Right now it is like
    this.
  • 5) Having a hard time providing OutlineColour value. I have RGBA
    value so how i can give it to OutlineColour

  Here is command i am using

  ffmpeg -y -i video-orignal.mp4 -i logo.png -filter_complex "[0] pad=width=iw:height=ih+200:x=0:y=100:color=#f2e6e6@0.99 [v_1];[v_1] drawtext=fontfile='/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf':text='this is watermark': fontsize=24: x=0.23333333333333*main_w: y=0.1325*main_h: fontcolor=#b01e1e: alpha=1,drawtext=fontfile='/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf':text='This is Top fixed text': fontsize=32: x=w-tw-2: y=(100-th)/2: fontcolor=#9e2643: alpha=1,drawtext=fontfile='/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf':text='This is Bottom fixed text': fontsize=32: x=w-tw-2: y=h-50: fontcolor=#9e2643: alpha=1 [v_2];[v_2] subtitles=f=subtitles-final.srt:force_style='FontName=DejaVu Sans Mono,FontSize=26,OutlineColour=&H00f2eded,PrimaryColour=&H000bf282,BorderStyle=3,WrapStyle=3,Bold=1,italic=1,Underline=1,Alignment=3,MarginV=86.4' [v_3];[v_3] [1]overlay=main_w-140:105 [v_4]" -map "[v_4]" -map 0:a video-final.mp4
