Direct Download M3U8 file playlist stream and convert into local MP4 video file 

echo "Enter m3u8 link:";read link;echo "Enter output filename:";read filename;ffmpeg -i "$link" -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 23 $filename.mp4

-bsf:a aac_adtstoasc

    bsf = (bit stream filter)
    use aac_adtstoasc bsf for a audio streams, this is need if .m3u8 file consists with .ts files and output is .mp4
    reference https://ffmpeg.org/ffmpeg-bitstream-filters.html#aac_005fadtstoasc

-c copy -vcodec copy

    skip codec (encode and decode), just demux and mux
    I guess .ts and .mp4, for video stream, they are both H.264 codec, just guess.
    reference https://ffmpeg.org/ffmpeg.html#Stream-copy

-crf 50

    reference https://trac.ffmpeg.org/wiki/Encode/H.264#CRFExample
    the example shows -c:a copy did not re-encode, guess this option is not needed here.
    And 0 is lossless, 23 is the default, and 51 is worst quality possible 😢
