  • FFMPEG concat cutting audio off after certain clip

    10 avril 2020, par legit_hacker_2000

    So I am creating multiple video clips in Python using FFMPEG, I am then trying to concat these together. I create multiple videos named result1000, result1001 etc, then I create a transition effect I want to layer between these videos. The result1000, result1001... etc concat together perfectly fine, however inserting the transition effect between them causes every clip after the first transition to lose audio.

    



    Creating the transiton

    



    ffmpeg -loop 1 -y -i media/templates/bg.png -i media/swoosh_sound.mp3 -shortest -acodec copy -vcodec libx264rgb output/swoosh.mp4


    



    Creating video clips

    



    ffmpeg -loop1 -y -i image_files/image+str(1000+i)+.png -i audio_files/audio+str(1000+i)+.mp3 -shortest -acodec copy -vcodec libx264rgb output/result+str(1000+i)+.mp4


    



    The ffmpeg_files.txt then looks something like this

    



    file 'output/result1000.mp4'
file 'output/result1001.mp4'
file 'output/result1002.mp4'
file 'output/result1003.mp4'
file 'output/result1004.mp4'
file 'output/swoosh.mp4'
file 'output/result1005.mp4'
file 'output/result1006.mp4'


    



    and the concat command im using is

    



    ffmpeg -f concat -safe 0 -i ffmpeg_files.txt output/no_bg_out.mp4


    



    In console on running the concat comment it will say

    



    [mov,mp4,m4a,3gp,3g2,mj2 @ 000001f289b44c40] Auto-inserting h264_mp4toannexb bitstream filter


    



    for each resultXXXX clip, then as soon as it reaches a transition clip it starts spamming

    



    [mp4 @ 000001aa093ad100] Non-monotonous DTS in output stream 0:1; previous: 13619623, current: 8777816; changing to 13619624. This may result in incorrect timestamps in the output file.


    



    I have read over the solutions mentioned Here but none of them seem to solve my issue. It should be noted that all video clips are created from .mp3 audio files and .png image files.

    


  • Ffmpeg/lavfi Is it possible to fade out an image overlay that was loaded with a movie= filter not a -i parameter

    26 avril 2022, par Baxter

    I've tried something like :

    


    movie='overlaylogo.png',fade=out:st=5:d=1[logo],[in][logo]overlay='0:0'[out]


    


    But it seems to stick on 100% opacity, adding in a loop=loop-1 and fps=24 filter after the movie= load seem to have little effect, is there some step required to convert an image into a video for fade to apply over ?

    


  • is that possible to use ffmpeg convert .mp4 to .ts when get a http request

    6 mars 2019, par koner

    I search some article that tell me should convert the mp4 first,then wait the request and send the ts and m3u8.

    But i looking for a way , that is when the request comes , then i will start to convert the video , and send the m3u8 immediately when the Conversion is not finish.

    If the request come , but the ts file not ready ,then wait still the file ready and send it immediately .

    Is that possible to do something like this ? or can use another way to have the same effect ?
