  • FFMpeg clip broken, generated from images [closed]

    5 février, par thomassss

    I hope someone can help me out here, would really appreciate it :).

    


    I created a video out of images, and then merged it with other videos.
The problem is that the final result is kinda broken - when I want to add background music to it, it won't play the music on the parts with the video generated by images, and on mobile phones it seems even more broken.

    


    The commands I used :

    


    Extracting the images from the video :

    


    ffmpeg.exe -i E:\dev\chatgpt\temp11\peng\final\1_runway.mp4 -vsync 0 -f image2 E:\dev\chatgpt\temp9\peng\final/1_runway-%06d.png


    


    Then I edit the images, then merging them back with :

    


    ffmpeg.exe  -i  E:\dev\chatgpt\temp11\peng\final\2_runway_final-%06d.png E:\dev\chatgpt\temp9\peng\final\5_runway_final.mp4



    


    This file now seems to be broken

    


    Now when i merge this file with other mp4s via

    


    ffmpeg.exe -f concat   -i E:\dev\chatgpt\temp11\peng\\final\ENGLISH_ffmpeg_input.txt  -vcodec copy -acodec copy E:\dev\chatgpt\temp9\peng\\final\ENGLISH_output.mp4


    


    Ad then add background music via

    


    ffmpeg.exe -i "E:\dev\chatgpt\temp11\peng\final\ENGLISH_output.mp4" -i "E:\dev\chatgpt\background.mp3" -filter_complex "[1:a]volume=0.2[a1];[0:a][a1]amix=inputs=2:duration=longest[a]" -map 0:v -map "[a]" -c:v copy -c:a aac -shortest "E:\dev\chatgpt\temp10\peng\final\ENGLISH_output_background.mp4"


    


    the background music isn't played in the parts with the "video generated from images".
Even VLC sometimes have problem displaying all parts correctly - that's why I added Youtube-links - this seems to work somehow.

    


    Does anyone have a clue how I can investigate further ?

    


    I tried converting both, the final video-file and the generated clip from images into different formats with different framerates - but nothing worked

    


    Thanks in advance !

  • ffmgep stucks while merging two streams at input 0 [closed]

    3 février, par Robi Tagore

    I tried to merge two streams downloaded before, I was using ffmpeg to combine them. I could use the path directly, but I felt it would'nt always be, so I read the steams, after I combine them,
everytime I run the code it std errs the following output, and creates merged.mp4 with 0 bytes, help me find the mistake

    


    code

    


    
const {spawn} = require("child_process");
const fs = require("fs")


var audio = fs.createReadStream("audio.aac")
var video = fs.createReadStream("video.mp4")



var ffprocess = spawn("ffmpeg",[
    '-y',
    '-i', 'pipe:0', 
    '-i', 'pipe:1',  
    '-c', 'copy',  
    '-f', 'mp4',    
    'pipe:2',   
])

video.pipe(ffprocess.stdin)
audio.pipe(ffprocess.stdin)


ffprocess.stdout.on("data")


ffprocess.stderr.on("data", (data) => {
    console.log(`ffmpeg stderr ${data}`);
});
  
ffprocess.on("close", (code) => {
if (code === 0) {
    console.log("FFmpeg process exited successfully");
} else {
    console.error(`FFmpeg process exited with code ${code}`);
}
});
