I have found this code to combine multiple images and one audio file into video, but what I want is the images to loop until the end of audio. So what I mean, if I have 5 images and each image is shown for 5 seconds, after 25 seconds show again the first image, second image etc and this will continue until the end of audio.
ffmpeg -r 0.2 -i Scan-130802-%04d.jpg -i "1.mp3" \
-vcodec libx264 -vf scale=1920:1080 \
-crf 25 -preset slow -acodec copy video.mp4
another problem I have is that with the above code the images appear horizontally flipped for some reason.
It's more efficient to do this in two steps.
#1
ffmpeg -framerate 1/5 -i Scan-130802-%04d.jpg -vf "scale=1920:1080,setsar=1" -r 5 -c:v libx264 -crf 25 -preset slow scan-video.mp4
#2
ffmpeg -stream_loop -1 -i scan-video.mp4 -i "1.mp3" -codec copy -shortest -fflags +shortest -max_interleave_delta 200M video.mp4

I am trying to do three tasks with FFMPEG
Crop a video without losing quality
Resize (upscale) the cropped video with good quality
Cut specific part of a the upscaled vided without losing quality
Here are the command line I use:
to crop: video og.mp4 to video og1.mp4
ffmpeg -i og.mp4 -vf "crop=1330:615:22:120" -c:v libx264 -crf 1 -preset veryslow -c:a copy og1.mp4
to resize: video og1.mp4 (converted above) to video og2.mp4
ffmpeg -i og1.mp4 -vf scale=1920:-1 -c:v libx264 -crf 1 -preset veryslow -c:a copy og2.mp4
to cut: video og2.mp4 (converted above) to og3.mp4
ffmpeg -i og2.mp4 -ss 00:00:08.190 -t 00:00:11.680 -c:v libx264 -crf 1 -preset veryslow -c:a copy og3.mp4
I want to achieve highest quality of 1920 width video (irrespective of height and size of the file)
Is there a way to get the above tasks in one command or shorter time with best quality?
Also advice if there is a better command or parameters to be used.
Thanks
You can combine all commands by using a single filterchain, and adding the trim as well
ffmpeg -ss 8.190 -t 11.680 -i og.mp4 -vf "crop=1330:615:22:120,scale=1920:-2" -c:v libx264 -crf 1 -c:a copy og1.mp4
With crf 1, a slow preset is unnecessary.
I use ffmpeg to convert a sequence of images to a video, i find that after i feed first image to it and almost 6 seconds later ffmpeg output first video frame to me.
I use command as follow:
ffmpeg -f image2pipe -r 100 -i pipe:0 -f flv -r 100 -tune zerolatency -preset ultrafast -bufsize 2M -codec:v libx264 -codec:a libmp3lame -bf 0 -muxdelay 0.001 -s 478x850 -b:v 2M pipe:1
Is my options is right?
Or others led to this result?
How can i get first video frame quickly once i feed the first frame?
Change probesize & analyzeduration options
I need your help. I stream to Twitch with this Command:
ffmpeg -i input.mp4 -i image.jpg -filter_complex 'overlay=x=10:x=10' -s \
1920x1200 -framerate 15 -c:v libx264 -preset ultrafast -pix_fmt yuv420p \
-threads 0 -f flv 'rtmp://'
How is it possible to change the image.jpg picture to another picture on a variable time? I will don't restart the FFMPEG Command.
Add the -f image2 -loop 1 input options for the image input, then atomically replace image.jpg when desired such as by using mv.
Basic example:
ffmpeg -i input.mp4 -f image2 -loop 1 -i image.jpg -filter_complex overlay output.mp4
Streaming example:
ffmpeg -re -i input.mp4 -f image2 -loop 1 -i image.jpg -filter_complex "overlay,format=yuv420p" -c:v libx264 -preset fast -g 50 -b:v 4000k -maxrate 4000k -bufsize 8000k -f flv 'rtmp://'
To answer the "variable time" part of your question use a cron job to run scripts that update the overlay image at a specified time i.e. every 5 mins. For example you can create a folder of various overlays and select one randomly every 5 minutes and copy it to image.jpg. FFMPEG will then render the new image to your stream.
It is important to use -f image 2 -loop 1 -thread_queue_size 512 -i image.jpg especially when rendering other image formats.
I want to convert jpg images to mp4 video without resizing image(keep original images size and well formated video)
I have tried lot's of solutions of ffmpeg and imagemagic (links given below)but both crop images after converting in video format and i want a video from images with original image size.
Solution will be appreciated with ffmpeg or imagemagick. :)

ffmpeg -framerate 1/5 -i na%03d.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4
on large image(1600X1200) its execute successfully but not generate a smooth video.
on small image(300x168) its show error. i also try this command on small image
ffmpeg -framerate 1/5 -i abc%03d.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4 -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2"
this work for me i use this in loop

Hi I am new in FFmpeg,
I have made video from slideshow of sequential images (img001.jpg, img002.jpg, img003.jpg....). Using following commands in Ubuntu 14.04
ffmpeg -framerate 1/5 -i img%03d.jpg -c:v libx264 -r 30 -pix_fmt yuv420p -vf scale=320:240 out.mp4
But now I want to put animation like fade-in, fade-out between each sequential images, I want to generate video,
can anybody help me how to make it, i have searched lots of things but could not get....
The best way to do this is create intermediate mpeg's for each image and then concatenate them all into a video. For example, say you have 5 images; you would run this for each one of the images to create the intermediate mpeg's with a fade in at the beginning and a fade out at the end.
ffmpeg -y -loop 1 -i image -vf "fade=t=in:st=0:d=0.5,fade=t=out:st=4.5:d=0.5" -c:v mpeg2video -t 5 -q:v 1 image-1.mpeg
where t is the duration, or time, of each image. Once you have all of these mpeg's, you use ffmpeg's concat command to combine them all into an mp4.
ffmpeg -y -i image-1.mpeg -i image-2.mpeg -i image-3.mpeg -i image-4.mpeg -i image-5.mpeg -filter_complex '[0:v][1:v][2:v][3:v][4:v] concat=n=5:v=1 [v]' -map '[v]' -c:v libx264 -s 1280x720 -aspect 16:9 -q:v 1 -pix_fmt yuv420p output.mp4
This gives you the desired video and is the simplest and highest quality solution with ffmpeg. Let me know if you have any questions about how the above command works.
