  • create video with fluctuated background color and drawbox with fluctuated color ?

    27 mai 2019, par Wang

    Is there anyway to create a video with fluctuated background color choosing from a list for example [R, G, B] the background color along time will be R,G,B,R,G,B .... I might use nullsrc with geq. But seems the geq is quite slow which apply to each pixel.

    I would also like to change the color of drawbox too, is there any easy way to do it ? I knew we might be able to use openclsrc but it seems overkill for this simple task.

    Update, for drawbox I found a way, which is kind of abuse the timeline editing :

    ffmpeg -f lavfi -i smptebars=r=30:d=30:size=800x600 -vf "drawbox=enable='eq(mod(n,3),0)':x=0:y=0:t=20:c=red,drawbox=enable='eq(mod(n,3),1)':x=0:y=0:t=20:c=green,drawbox=enable='eq(mod(n,3),2)':x=0:y=0:t=20:c=blue" /tmp/test_box.mp4

  • Merging RGB Channels in FFMPEG [migrated]

    14 octobre 2016, par Draconis

    I have three grayscale videos, representing the red, green, and blue channels from a video. I extracted them using the extractplanes filter, and sent them through different pipelines.

    Now I would like to combine them again. But while extractplanes is working perfectly, mergeplanes is not. My initial attempt was this :

    [r][g][b] mergeplanes=0x001020 [output]

    This interprets my RGB channels as YUV, which is not what I want. My next attempt was this :

    [r][g][b] mergeplanes=0x001020:rgb24 [output]

    But according to the error message, Only planar formats with more than one component are supported. (Same for all other RGB and RGBA pixel formats I tried.)

    Is there another way to put these channels back together ? Or some way to convince mergeplanes to output RGB ?

  • Need to set Multiple drawtext in same line one after the other. but unable to do so via FFMPEG command

    9 septembre 2019, par balpreet singh

    Hi Am trying to create a FFMPEG command for Text overlay on video that has partially text as bold. I am using the following command. but am unable to figure out how to pass the x position of 1st ending part.

    ffmpeg -i b.mp4 -vf "drawtext=fontfile=arial.ttf:text='Title of this video is ':fontcolor=blue:fontsize=20,drawtext=fontfile=ariali.ttf:text='How to have a healthy Life':fontcolor=yellow:fontsize=20:x=**<width of="of" 1st="1st" text="text">**" -c:v libx264 -c:a copy -movflags +faststart output.mp4 -y
