• Ffmpeg rounds seconds instead of using the milliseconds part

  10 mai 2021, par NourElDineA

  I tried to cut a video using the following command :

  


  ffmpeg -i input.mp4 -ss 00:00:00 -to 00:00:06.600 output.mp4


  


  When I run the command ffmpeg rounds up and the output video is 7 seconds instead of 6.6 seconds.
I would like to know if there is a way to cut the video precisely where I tell it to.

  


  Here is the log file content :

  The output file is 7 seconds long which means ffmpeg rounded up my 6.60 to 7 and I need it to cut exactly at 00:00:06.60

  


• Trying to add Watermark to Video FFMPEG

  8 mai 2021, par Michael Bouix

  I'm trying to add watermark to my video
When I upload some videos work fine, but some videos I get an error that retrieve the file with 0kb.
I don't know if its why the video is 4k... I have no idea
And I'm running another command to scale the video with the same file and work fine too, only when adding my watermark I get the error

  


  This is the command :

  


  $comando_arquivo_water = "/usr/bin/ffmpeg -nostdin -i ".$path_video." -i ".$path_logo." -filter_complex '[1][0]scale2ref=w=oh*mdar:h=ih*0.2[logo][video];[video][logo]overlay=(W-w)/2:(H-h)/2' -y ".$water_final_nome." > out.txt 2> err.txt";


  


  And this is what I'm getting
