Is there a way to program the (Download) button to save a group of images as a one video ?
9 février 2024, par Lina Al-fawzanThis is my entire code. Its function is that everything the user writes or says will have images returned to him according to what he wrote/said, and the next image will be shown to him after he presses “close,” and he can save each image separately. I want to make a simple modification to it. First, instead of a close button, I want each image to be displayed for 3 seconds and the next one to be displayed, and so on... “all of them in one window”, and for the “download” button to be when the last image is displayed, and for them all to be saved in one video.

Next drawtext clears the previous one ffmpeg
27 août 2021, par Макс Шульдинерffmpeg.exe -i ffmpeg_inputs/zheltiy_chelik.mp4 -vf "[in]drawtext=fonts/Temporarium.otf:text='r':fontcolor=orange:fontsize=100:x=(w-text_w)/2+0:y=0:enable='between(t,0, 11)', drawtext =fonts/Temporarium.otf:text = 'r':fontcolor=orange:fontsize=100:x=(w-text_w)/2+20:y=0:enable='between(t,11, 22)', drawtext =fonts/Temporarium.otf:text = 'r':fontcolor=orange:fontsize=100:x=(w-text_w)/2+40:y=0:enable='between(t,22, 33)'[out]" ffmpeg_outputs/test2.mp4 -y 


There is such a ffmpeg line. Its meaning is to draw a letter 20 pixels to the right of the current position of the word every 11 seconds, and in this way "write the word". But here's the problem - when the second letter starts to render, it overwrites the first, and the third, respectively, overwrites the second. The string seems to have prescribed [in] and [out] but does not help, maybe someone has ideas

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 :
