  • How to merge multiple videos and audios in python ffpmeg [closed]

    18 décembre 2020, par Alireza Farzaneh

    I'm making a program for downloading Adobe connect based meetings' recordings using python.
I have managed to download Adobe connect sessions' recording.
    
Now I have multiple separate audios and videos.
    
I'm trying to merge them into one video using python and ffmpeg library.
    
The problem is that I want them to be in sync.
    

    
Here is an example :
    
I have four files :

    "cameraVoip_0_4.flv" : audio, started at "Sat Nov 07 13:36:11 2020" and lasted for 2888.128000 seconds.

    "cameraVoip_0_6.flv" : audio, started at "Sat Nov 07 14:26:42 2020" and lasted for 366.455 seconds.

    "screenshare_1_2.flv" : video, started at "Sat Nov 07 13:36:01 2020" and lasted for 2844.602000 seconds.

    "screenshare_3_7.flv" : video, started at "Sat Nov 07 14:26:51 2020" and lasted for 352.635000 seconds.


    
I want to merge them somehow that their timing would be correct.

    


  • FFMPEG Conversion from GIF to video with audio, take too long

    5 novembre 2020, par Mouaad Abdelghafour AITALI

    I'm trying to convert a GIF file into 720p video and merge it with audio, the code below works fine, but it takes a long time to finish the process (depends on the audio length) :

    


    //Converting from GIF to video is fast!

public static String makeVideo(String inputGifPath, String outputPath, int width, int height) {
        return "-y -i " + inputGifPath + " -movflags faststart -pix_fmt yuv420p -vf crop=" + width + ":" + height + ":0:40,scale=1280:720,setsar=1 " + outputPath;
    }



//Merging video with audio takes a lot of time!

public static String addAudio(String audioNoSpace, String inputVideoPath, String outputVideoPath) {
    return "-stream_loop -1 -i " + inputVideoPath + " -i " + audioNoSpace + " -shortest -map 0:v:0 -map 1:a:0 -y " + outputVideoPath;
}


    


    FFMPEG commands :

    


    -y -i file.gif  -movflags faststart -pix_fmt yuv420p -vf crop=540:250:0:40,scale=1280:720,setsar=1 video.mp4

-stream_loop -1 -i video.mp4 -i  audio.wav -shortest -map 0:v:0 -map 1:a:0 -y final_video.mp4
