• FFPMEG Adding Watermark Is Producing An Error

  19 janvier 2021, par Glen Elkins

  I have an mp4 video and i'm using FFMPEG on command line in php to add an image to the bottom right corner as watermark :

  


  shell_exec('ffmpeg -y -i ' . $videoPath . ' -i ' . $path . ' -filter_complex "overlay=x=(main_w-' . $logoWidth . ')-10:y=(main_h-' . $logoHeight . ')-10" ' . $videoPath);


  


  It overwrites the original video with the new one. The logo is added to the video but the video ends up being 0 seconds long (originally 1 minute) and i see this error when the command is run :

  


  


  [h264 @ 0x134e540] Invalid NAL unit size (20328 > 14044). [h264 @
0x134e540] Error splitting the input into NAL units. Error while
decoding stream #0:0 : Invalid data found when processing input

  


  


  I have absolutely no idea what this means. Here is the entire output of the command :

• How do I fade out the edge of a video with ffmpeg ?

  11 décembre 2020, par Jared

  I have a transparent .mov and I want to "fade out" only one edge of the video into transparency using ffmpeg.

  


  My video is transparent 1000x1000 (black is transparent) :

  



  I am trying this command :

  


   ffmpeg -i movie.mov -b:v 700K -filter_complex "[0]split[v0][v1];[v0]format=yuva420p,geq=r=0:g=0:b=0:a=255*(Y/H),scale=w=1*iw:h=200[fg];[v1][fg]overlay=0:800:shortest=1" converted.mov


  


  This half works as the image has the gradient fade out but loses all transparency :

  



  What am I doing wrong ?

  


  Full output log of command :
