ffmpeg set watermark using java
20 mai 2020, par SynixQueenI want to add a watermark( like .png) to a video.
This is the way for the command line :





ffmpeg -i input.mp4 -i watermark.png -filter_complex "overlay=1500:1000" output.mp4





found >here<



my Implementation so fairs like that :



FFmpegResult result = FFmpeg.atPath(Setup.getBin())
 .addInput(UrlInput.fromPath(inFile.toPath()))
 .addInput(UrlInput.fromPath(picture.toPath())
 .setDuration(10, TimeUnit.SECONDS)) // set duration time
 .setComplexFilter(FilterGraph.of(
 Filter.withName("overlay")
 .addArgument("20","20")
 .addOutputLink("lowerright")
 ))
 .addOutput(UrlOutput.toPath(output.toPath()))
 .execute();



at the point .setComplexFilter I am unsure I cannot find any sources to get this right atm 
like here >FFmegDokumentation<



any ideas ?

Ffmpeg Watermark Scaling Issue
10 mai 2020, par Tevin MosleyI am using the code below to watermark videos



set ffmpeg="C:\ffmpeg\ffmpeg.exe"
set ffprobe="C:\ffmpeg\ffprobe.exe"

setlocal disabledelayedexpansion
for %%a in ("G:\4 - Watermark Process\Before\*.mp4") do (
 for /F "delims=" %%I in ('
 ffprobe -v quiet -show_entries stream^=width -of csv^=p^=0:s^=x "%%a"
 ') do (
 ffmpeg -i logo.png -y -v quiet -vf scale=%%I*0.25:-1 scaled.png
 ffmpeg -i "%%a" -vf "movie=scaled.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h [out]" "G:\4 - Watermark Process\After\%%~na.mp4"
 )
)

pause 10



The only problem with this is the scaling is not good for videos that have a bigger width than height.



If I watermark a video that is 608w x 1080h the watermark works perfectly but for 1920w x 1080h it is way too big.



I am trying to add a part to the script where the video height can be considered but everything I add breaks the script.



Any ideas ?

FFmpeg concatenate video and add watermark
18 avril 2020, par user7356972I have command to overlay two video one on other.



ffmpeg -i input.mp4 -vf "movie= overlay.mov [a]; [1][a]scale2ref[2nd][ref];[2nd][ref]overlay=0:0 [c]" output.mp4 



Now I want to add water watermark and concatenate a new video
append.movin above command. I have found a command to add watermark.


ffmpeg -i output.mp4 -i watermark.png -filter_complex "overlay=10:10" outputwatermark.mp4



But I want to merge both the command and also need to concatenate
append.movtooutput.mp4.


Also above overlay two video command takes too long time to process if video size is large. Any suggestion on that(should not affect quality of video) ?



I tried following command to concatenate video.



ffmpeg -i abc.mp4 -i ../input/overlay2.mov append.mp4



The video was not concatenate, below is the output.
