• How to download .m3u8 in once time

  11 octobre 2024, par Nabi K.A.Z.

  I have a .m3u8 file on remote host, with contain fixed numbers of chunk .ts file name, and not stream :

  



  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:11
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:9.736,
media_0.ts
#EXTINF:9.96,
media_1.ts
#EXTINF:10.0,
media_2.ts
#EXTINF:10.0,
media_3.ts
#EXTINF:10.0,
media_4.ts
#EXTINF:10.2,
media_5.ts
#EXTINF:10.0,


  



  When I use this command :

  



  # ffmpeg -i "http://example.com/chunklist.m3u8" file.mp4

frame=  582 fps=9.4 q=28.0 size=    1536kB time=00:00:23.21 bitrate= 542.1kbits/s dup=2 drop=4 speed=0.375x


  



  It works. But It get frame by frame video and very long time needed. (It takes time almost to playback the video.)

  



  But since the path of all the .ts files are known. (http://example.com/media_0.ts, http://example.com/media_1.ts, ...) There must be a way to get and merge them all at the same time.

  



  But How in ffmpeg directly ?!

  



  EDIT (try a solution) :

  



  For one solution, I know how can concatenation files with ffmpeg.

  



  ffmpeg -i "concat:0.ts|1.ts|2.ts|3.ts|4.ts|5.ts" -c copy output.mp4


  



  This ffmpeg command was great, and works in less 1 sec time !

  



  So try to download all .ts files with CURL with this command :

  



  curl \
http://example.com/media_0.ts -o 0.ts \
http://example.com/media_1.ts -o 1.ts \
http://example.com/media_2.ts -o 2.ts \
http://example.com/media_3.ts -o 3.ts \
http://example.com/media_4.ts -o 4.ts \
http://example.com/media_5.ts -o 5.ts


  



  But you can see result :

  See, total download time was 72 sec, while the total duration of all parts is 59 sec ! that this time is very long !

  



  So sorry, download all parts and then concat that, was not good solution.

  



  EDIT 2

  



  I try for another .m3u8 file on the another server with difference URL :

  



  Download and concat together :

  



  ffmpeg -i "concat:\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_0.ts|\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_1.ts|\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_2.ts|\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_3.ts|\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_4.ts|\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_5.ts\
" -c copy -y output.ts


  



  Another command with input.txt URLs file.

  



  ffmpeg -f "concat" -i "input.txt" -c copy -y output.ts


  



  input.txt file :

  



  file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_0.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_1.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_2.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_3.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_4.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_5.ts'


  



  Or this command some time if needed :

  



  ffmpeg -f "concat" -safe "0" -protocol_whitelist "file,http,https,tcp,tls" -i "input.txt" -c copy -y output.ts


  



  Finally, for that download speed was good, MAYBE my server target has limited bandwidth. :-(

  


• How to download a video from m3u8 with aes-128, IV with FFMPEG ? [closed]

  13 avril 2021, par AWrr

  I've tried with a tutorial that prompted me to download the m3u8 file and then stream it with vlc but that didn't work. It just created a 160 bytes .mp4 file that couldn't be played.

  


  When I opened it, it contains a line in the form of :

  


  #EXT-X-KEY:METHOD=AES-128,URI="license://G",IV=0x08

  


  I've read some threads talking aboout a .key file, but this one doesn't have a .key in the "URI=" section and I don't really knoe how to get one, if I needed it.

  


  Will ffmpeg -i playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mkv work just fine ?

  


  Edit : I've tried it and it showed this :

  


  At the start
 Unable to open key file

  


  At the end

  


    Stream #0:0 -> #0:0 (copy)

Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)```



  


• Youtube-dll how to get a direct download link to the merged file without creating a temp file on server

  11 juillet 2019, par CeylonDomains Solutions

  Is there any way to create a direct download link to the merged file without creating a temp file on the server in youtube-dll ?

  youtube-dll -f 255+160 https://youtu.be/p-flvm1szbI 

  The above code will merge the file and output the merged file.

  I want to allow users to directly download the merged file to their computers — without creating any temp file on my server. Is this possible ?

  (Creating a temp file and then letting the user download it is already possible.)
