FFMPEG : How to mix different types of image sequence inputs when creating multiple streams
9 août 2021, par chutliesI am using a piece of software that generates a .txt files with rendered images. The list within that txt files is printed with the word 'file' at the beginning of the file path.


Ex : file 'file:C :/Users/User/Desktop/test/Test.0001.png'


I am attempting to input another image sequence as an overlay. Everything works fine if I just overlay, scale, and render. So this works fine :


ffmpeg -hide_banner -y -f concat -safe 0 -i C:/test/input.txt -i "C:/test/BALL.%04d.png" -filter_complex "overlay[4K_in];[4K_in]scale=1920:1080[hdOut]" -map [hdOut] hd.mp4



But when I start to split the stream to create different outputs it will only render the overlayed stream [1:v] and not the composited image.


ffmpeg -hide_banner -y -f concat -safe 0 -i C:/test/input.txt -i "C:/test/BALL.%04d.png" -filter_complex "overlay,split=3[mp4HD_in][mxf720_in][mov4K_in];[mp4HD_in]scale=1920:1080[mp4HD_out];[mxf720_in]scale=1280:720[mxf720_out];[mov4K_in]scale=3840:2160[mov4K_out]" -crf 16 -vcodec libx264 -map [mp4HD_out] C:/test/hdMP4.mp4 -vcodec prores -map [mov4K_out] C:/test/MOV4K.mov -vcodec dnxhd -pix_fmt yuv422p -b:v 75M -map [mxf720_out] C:test/MXF720.mxf



If I remove 'file' from the frames file path in the .txt file it works.


Ex : file 'C :/Users/User/Desktop/test/Test.0001.png'


Unfortunately, I am unable to change this as it's being generated and run within a piece of software. Are there any flags or something that I need to add to get around this ? Any other possible techniques beyond starting another &&ffmpeg call to generate the streams over the overlay ?


I do get this in the logs :

ffmpeg can't concat movies from two different devices
29 mars 2017, par T4ng10rI’ve got bunch of movies from two different Panasonic devices. As long as I concat movies from only ONE device - final movie is smooth.
However, when I add movie clip from second device, right after final movie ends playing movies from first device it display audio and only still images from movie clip from other device.ffmpeg -f concat -i mylist.txt -c copy final_movie.MP4
