  • linux : m3u8 : how to manually download and create an mp4 from segments listed in .m3u8

    28 juillet 2024, par Santhosh

    I have an .m3u8 url i.e http://example.com/test.m3u8

    



    I can download it by ffmpeg command :

    



    ffmpeg -y -loglevel verbose -i "http://example.com/test.m3u8" -c copy -f mpegts test.mp4


    



    But i am trying to do this manually :

    



    I tried the following :

    



    1) download the m3u8 file :

    



    wget -O test.m3u8 "http://example.com/test.m3u8"


    



    2) then download each segment into a folder :

    



    aria2c -i test.m3u8


    



    this downloads all the .ts files in the folder.

    



    3) then i combine them

    



    cat *.ts > out.ts


    



    4) then i try to convert to mp4 :

    



    $ ffmpeg -i out.ts -c:v libx264 outputfilename.mp4

  • Specifying audio/video for a multiple stream/multiple file setup using ffmpeg

    31 mai 2018, par Robert Smith

    Folks, I have the following ffmpeg command :

    ffmpeg
    
    -i video1a -i video2a -i video3a -i video4a
    
    -i video1b -i video2b -i video3b -i video4b
    
    -i video1c

        [1:v] setpts=PTS-STARTPTS+ 300/TB, scale=320x240 [2a];
    
        [2:v] setpts=PTS-STARTPTS+ 400/TB, scale=320x240 [3a];
    
        [3:v] setpts=PTS-STARTPTS+ 400/TB, scale=320x240 [4a];
    
        [4:v] setpts=PTS-STARTPTS+2500/TB, scale=320x240 [1b];
    
        [5:v] setpts=PTS-STARTPTS+ 800/TB, scale=320x240 [2b];

        [7:v] setpts=PTS-STARTPTS+ 800/TB, scale=320x240 [4b];
    
        [8:v] setpts=PTS-STARTPTS+3000/TB, scale=320x240 [1c];
    
        [base][1a] overlay=eof_action=pass [o1];
    
        [o1][1b] overlay=eof_action=pass [o1];
    
        [o1][1c] overlay=eof_action=pass:shortest=1 [o1];
    
        [o1][2a] overlay=eof_action=pass:x=320 [o2];
    
        [o2][2b] overlay=eof_action=pass:x=320 [o2];
    
        [o2][3a] overlay=eof_action=pass:y=240 [o3];
    
        [o3][3b] overlay=eof_action=pass:y=240 [o3];
    
        [o3][4a] overlay=eof_action=pass:x=320:y=240[o4];
    
        [o4][4b] overlay=eof_action=pass:x=320:y=240"
    
    -c:v libx264 output.mp4

    I have just found out something regarding the files I will be processing with above command : that some mp4 files are video/audio, some mp4 files are audio alone and some mp4 files are video alone. I am already able to determine which ones have audio/video/both using ffprobe. My question is how do I modify above command to state what each file contains (video/audio/both).

    This is the scenario of which file has video/audio/both :

    video   time
    
======= =========
    
Area 1:
    
video1a    audio
    
video1b     both
    
video1c    video
    

    
Area 2:
    
video2a    video
    
video2b    audio
    

    
Area 3:
    
video3a    video
    
video3b    audio
    

    
Area 4:
    
video4a    video
    
video4b    both

    My question is how to correctly modify command above to specify what the file has (audio/video/both). Thank you.

    Update #1

    I ran test as follows :

    -i "video1a.flv"
    
-i "video1b.flv"
    
-i "video1c.flv"
    
-i "video2a.flv"
    
-i "video3a.flv"
    
-i "video4a.flv"
    
-i "video4b.flv"
    
-i "video4c.flv"
    
-i "video4d.flv"
    
-i "video4e.flv"
