Remove tiktok video logo/watermark using laravel/ffmpeg ?
10 août 2022, par royallifeHow I can remove tiktok video logo/watermark using FFmpeg ? Like most sites are doing e.g https://ssstik.io/en


I tried to remove the logo using delogo filter https://github.com/protonemedia/laravel-ffmpeg but it leaves a blur effect in the video while the above site logo removal is clean, with no blurry effect.


Sample code :


$video = FFMpeg::open('public/tiktok/video2.mp4');
$video->addFilter(function ($filters) use ($bottom_coordinates) {
 $filters->custom( 'delogo=x=10:y=10:w=150:h=77');
 })
 ->export()
 ->inFormat(new \FFMpeg\Format\Video\X264)
 ->toDisk('public')
 ->save('7118695488282447131_delogo.mp4');


Any help ?
Thanks in advance.

Add logo on concatenated video
5 septembre 2020, par ottpeterI'm trying to add a logo on top of a concatenated video. The video concatenation and the adding of the logo should be in the same filter complex. My filter complex currently looks like this (it is generated by Bash) :


[0:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v0];[1:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v1];[2:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v2];[3:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v3];[4:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v4];[5:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v5];[6:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v6];[7:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v7];[8:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v8];[9:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v9];[10:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v10];[11:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v11];[12:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v12];[13:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v13];[14:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v14];[15:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v15];[16:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v16];[17:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v17];[18:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v18];[19:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v19];[20:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v20];[21:v]scale=854:480:force_original_aspect_ratio=1,pad=width=854:height=480:x='if(lt(in_w,854),(854-in_w)/2,0)':0,setsar=1[v21];movie=/home/logo.png, scale=180:-1 [logo];
[v0][v1][v2][v3][v4][v5][v6][v7][v8][v9][v10][v11][v12][v13][v14][v15][v16][v17][v18][v19][v20][v21] concat=unsafe=1:n=22:v=1:a=0[conc]; [conc][logo] overlay=50:50 [outv];


On 0bin, it is easier to read. So, there is a really long video concatenation part, and on the end, I would try to add the logo like this :




[conc][logo] overlay=50:50 [outv] ;




This is the error I'm getting :


[AVFilterGraph @ 0x5640862fc520] No such filter: '' 
Error initializing complex filters.
Invalid argument


How to do this correctly ?


EDIT :
This is the Bash script :


echo "Creating the video list..."
 # Number of videos
 VID_NUMBER=$(find $VIDS_PATH -maxdepth 1 -type f -printf . | wc -c)
 # File names can not contain spaces. INPUT_LIST will contain the list of input files, all files in VIDS folder.
 INPUT_LIST=""
 for file in $VIDS_PATH*
 do
 if [ ${file: -4} == ".jpg" ]
 then
 INPUT_LIST="${INPUT_LIST} -loop 1 -t $IMAGE_DURATION -i $file"
 else
 INPUT_LIST="${INPUT_LIST} -i $file"
 fi
 done

 echo "Creating filter complex..."
 # This is the beginning of the filter that is used for concatenation. Has to be an entry for all videos.

 done

 # Insert logo
 FILTER_COMPLEX_LIST="${FILTER_COMPLEX_LIST}movie=$LOGO, scale=180:-1, setpts=PTS-STARTPTS [logo];"

 # Filter final line. This is also generated in a loop. Tells ffmpeg which videos to concat and specifies output [outv]. No sound.
