Chaining drawtext to overlay in FFMPEG
14 juillet 2018, par alan samuelI am trying to add some text to a video using draw text. Is it also possible to use fontcolor to white ?
Here is my command I am trying
ffmpeg -i test.mp4 -i Watermark.png -filter_complex "[0:v][1:v] overlay=0:0:enable='between(t,5,30)'[v]; [0]volume=0:enable='between(t,5,30)'[a];drawtext=fontsize=50:fontfile=FreeSerif.ttf:text='This screen is redacted':x=(w-text_w)/2:y=(h-text_h)/2" -map "[v]" -map "[a]" -preset ultrafast output.mp4
I get - Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_drawtext_2
With the below answer it is failing for this video.

merge multiple videos and images dynamically using ffmpeg [duplicate]
16 avril 2018, par robert tamunoemiThis question already has an answer here :
I am trying to merge several images and videos together. When there is more than one video, the audio of the next video is lost. Here is my command :
$filter = "[0][1][2][3][4]concat=n=5:v=1:a=0,scale=320:240";
$cmd = 'ffmpeg -y -i videos/video__152344425320.mp4 -loop 1 -framerate 24 -t 10 -i images/4_152222487376001.png -i videos/video__152344425320.mp4 -loop 1 -framerate 24 -t 10 -i images/4_152222487376002.png -loop 1 -framerate 24 -t 10 -i images/4_152222487376003.png -filter_complex '.$filter.' out.mp4';
shell_exec($cmd.' 2> log.txt');This works but when I set
concat=n=5:v=2:a=1
, I get this error :ffmpeg version N-89674-g57d0c24132 Copyright (c) 2000-2018 the FFmpeg developers

creating a video using ffmpeg command with image name pattern [duplicate]
21 mars 2018, par Junaid FarooqThis question already has an answer here :
I am coming from this question
https://askubuntu.com/questions/610903/how-can-i-create-a-video-file-from-a-set-of-jpg-imagesEverything is working fine and I can create a video, I am only struggling with the image name pattern. Each time, I had to rename all files first to a specific pattern.
Can we create a video using the same command written below but with this kind of image name pattern ?

ffmpeg -framerate 25 -i image-%04d.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4
but this one using
image-2000.jpg image-2400.jpg image-2800.jpg
above image pattern.
Is there any possibility to use the above pattern of files which are being named as a date. also, all these images are in a folder. Can FFMPEG address them ?
