How do I fade out the edge of a video with ffmpeg ?
11 décembre 2020, par JaredI 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 ?

PHP FFMPEG AUDIO ARTWOARK METADATA
12 novembre 2020, par Ali SkantmediaI am using laravel-ffmpeg Package and I want to put the image on the audio file.
My code is as follows :


$thumbnailUrl = Storage::disk('thumbnail')->path($thumbnailPath);
 $audioUploaded->filters()->addMetadata([
 "title" => $song->title_en,
 "artist" => "firs artist",
 "album" => 'album name',
 "album_artist" => 'second artist',
 "track" => 2,
 "year" => 2020,
 "genre" => 'persian',
 "comment" => 'comment',
 "artwork" => $thumbnailUrl
 ]);



But I make a mistake. How do I insert an image of an URL or file system disk into an audio file ?


In documentation :


$audio->filters()->addMetadata(["artwork" => "/path/to/image/file.jpg"]);

FFPMEG Adding Watermark Is Producing An Error
19 janvier 2021, par Glen ElkinsI 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 :
