FFmpeg scale pad with watermark error parsing filterchain
21 février 2024, par nicoverI'm trying to scale a landscape video to full screen ratio with black pad around and add a watermark above, running this command :


-i videoInput.MP4 
-i watermark-.jpg 
-filter_complex 
[0:v]scale=720.0:720.0*0.59,pad=720.0:720.0*1.77:(ow-iw)/2:(oh-ih)/2:black[main][1:v]scale=iw*0.56:-1[v1];[main][v1]overlay=0:0 
-c:v libx264 -c:a copy -preset ultrafast -y output.mp4



And then I'm getting this error :


[AVFilterGraph @ 0x2825f38a0] Trailing garbage after a filter: scale=iw*0.56:-1[v1];[main][v1]overlay=0:0

[AVFilterGraph @ 0x2825f38a0] Error parsing filterchain '[0:v]scale=720.0:720.0*0.59,pad=720.0:720.0*1.77:(ow-iw)/2:(oh-ih)/2:black[main][1:v]scale=iw*0.56:-1[v1];[main][v1]overlay=0:0' 

around: scale=iw*0.56:-1[v1];[main][v1]overlay=0:0

Error initializing complex filters.
Invalid argument



I'm not able to found the error around the filter graph.


Is the filter graph incorrect ? How to fix it ?

PHP and FFMPEG Remove Code in Video [on hold]
6 janvier 2015, par user580950I have set of videos where i need to remove the code ( check below screen grab as an example ), you can see the code in RED .NOt sure if its possible to do it using PHP & ffmpeg or similar to detect a black box or hash key or serial no and blur out.
It must be able to use mpeg-ts file input and output with mpeg-ts.
Detection must be done and blurring must start 5 (configurable) seconds before the black box appears, this means we have to buffer the video and blur out the position where it will appear before it does.

21 février 2017, par Atif ImranI’ve found that videos with codec

have no problem with my code here. But when I use a video of codecH.264, AAC
(Sent from Android device) the videos are again black. Now my question is how do I convert a video to iOS playable codec.
