• How can I download a video with url beginning with blob:https://…

  11 août 2017, par iMax

  I would like to know if it is possible to download a video from a URL beginning with blob :

  blob:https://www.xyz123…

  i would prefer a terminal solution (ffmpeg ?, youtube-dl ?). but i have not found anything on the world wide web.

  Again : I have the url of the video stream, which looks like the above. How can I download the complete video ?

  Update

  Ok. I now found a webpage which allowed me to download the video file I wanted :
  https://video-download.online/

  But I am still wondering if there is a Terminal solution for downloading video with blob-URL (like in arte mediathek [ example arte ] or in zdf mediathek [ example zdf ]).

  Does nobody know how to do it ?

• 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. :-(

  


• Making youtube-dl download mp3's faster

  12 novembre 2017, par sciencelord

  It takes a long time to download mp3 songs using youtube-dl, and it takes even longer when downloading a bunch of mp3 songs. Is there a way to make it significantly faster ? I don’t mind reducing quality. I’ve been using the command below.

  youtube-dl --extract-audio --audio-format "mp3" --output "%(title)s.%(ext)s" "https://www.youtube.com/watch?v={videoid}

  I also took a look at this post :
  ffmpeg command for faster encoding at a decent bitrate with smaller file size

  But I wasn’t sure how to change the above command using the ffmpeg modifications.

  Thanks !
