ffmpeg specify image start/end time by seconds in slideshow
31 décembre 2022, par MartinI have an ffmpeg command that when ran on command prompt in win10, will combine 2 mp3 files and 1 image file into a low resolution .mkv video file.


06:23 = 383 = song1.mp3 length
05:40 = 340 = song2.mp3 length
12:03 = 723 = estimated total video length
12:04 = 724 = actual video length



Command that generates video file :


ffmpeg -loop 1 -framerate 2 -i images/img1.png -i "audio files/song1.mp3" -i "audio files/song2.mp3" -c:a pcm_s32le -filter_complex concat=n=2:v=0:a=1 -vcodec libx264 -bufsize 3M -filter:v "scale=w=640:h=638,pad=ceil(iw/2)*2:ceil(ih/2)*2" -crf 18 -pix_fmt yuv420p -shortest -tune stillimage -t 724 audioAndImageIntoVideo.mkv 



The current command just uses
-i images/img1.png
as a static image for the entire video. But I want to have one image for the duration of the first song, and a second image for the duration of the second song. With a timeline like so :

song1.mp3 and img1.png start at 00:00 and end at 06:23 ( 383 seconds )
song2.mp3 and img2.png start at 06:23 ( 383 seconds ) and end at 12:03 ( 723 seconds )



is there any flag to specify the timeline of two images ? Right now I am just trying to get them in order in a video, and then I can change the individual img resolution / size / stretching details for how it fills the frame
