  • I want to use image as a background of a drawtext video using ffmpeg

    8 janvier 2018, par Femzy

    Currently i am able to create video with ffmpeg using the drawtext filters to draw text on a black background Now Remain one thing that seems difficult to me, I thought it would be easy until i come to discover i don’t got it right. I want to use an image as background for the drawtext filters. I.e I want to use image as background of the video instead of using the background color or video background. Please someone should take me through on this this is my code `

    echo shell_exec('ffmpeg -f lavfi -i color=color=black -vf drawtext="textfile=text.txt:expansion=normal:fontfile=FreeSerif.otf: y=h-line_h-20:x=-100*t: fontcolor=white: fontsize=50" -t '.$words_count.' textover09.mp4 -report'); `

  • ffmpeg : trsfer a h264 video to a series of jpg failed

    However, this command works perfectly fine on random h264 videoes on the internet, so I guess there may be something wrong with our h264 video, but the weird thing is that it can be played by vlc player just fine...

    Any idea what the problem can be ? Any help will be appreciated !
