  • How to solve the problem of low performance of complex video generation using ffmpeg ?

    21 novembre 2019, par Zedd

    I use ffmpeg to generate a complex video.

    This video consists of the following materials :

    1. Original video

    2. Video dub

    3. Background music

    4. Subtitle

    My code logic is as follows

    1. Combine ’Original video’ and ’Video dub’ into ’Video A’

    2. Subtitle ’Video A’ as ’Video B’

    3. Add ’Background music’ for ’Video B’ as ’Video C’

    The ’Video C’ is the video I want.

    My Code

    // Step1:
    
ffmpeg -i VideoDub.mp3 -i OriginalVideo.mp4 VideoA.mp4
    
// Step2:
    
ffmpeg -i VideoA.mp4 -vf subtitles=Subtitle.srt -y VideoB.mp4
    
// Step3:
    
ffmpeg -i VideoB.mp4 -i BackgroundMusic.mp3 -filter_complex "[1:a]aloop=loop=-1:size=2e+09[out];[out][0:a]amix" -ss 0 -t 100 -y VideoC.mp4

    Design defect

    • I think my code is very redundant
    • poor performance
    • There are many times of encoding
    • It takes too long to generate such a video
    • The CPU usage has reached 100%.

    My Question

    How to solve the above problem？
