    # Download stream video
    ## Simple and recommended way (https://superuser.com/questions/692990/use-ffmpeg-copy-codec-to-combine-ts-files-into-a-single-mp4)
    ```
    The correct way to concat multiple video files from m3u8 playlist is

    ffmpeg -i "index.m3u8" -codec copy output.mp4
    The correct way to concat multiple video files from m3u8 playlist is

    ```
    ffmpeg -protocol_whitelist "file,http,https,tcp,tls" -i "index.m3u8" -codec copy output.mp4
    ```
    the m3u8 playlist can be on web or locally in directory
    it contains list of file paths relative to the playlist
    -codec copy to avoid encoding
    container type matters:
    *.mp4 is fine but it seems little slow to mux when playlist is fetched from web
    *.mkv or *.ts worked best for me

    if your m3u file looks like
    ```
    #EXTM3U
    #EXT-X-PLAYLIST-TYPE:VOD
    #EXT-X-TARGETDURATION:2
    #EXT-X-VERSION:3
    #EXT-X-MEDIA-SEQUENCE:0
    #EXTINF:2
    segments/1_vs0_00000.ts
    #EXTINF:2
    segments/1_vs0_00001.ts
    ```
    you need to add url before segments


    ## Long winded way
    ```
