• Download TS files from video stream

  8 juillet 2021, par Nicky Smits

  Videos on most sites make use of progressive downloading, which means that the video is downloaded to my computer, and easy to trace. There are lots of extensions out there to do this, and even in the dev-tools this is easily done.

  



  On certain websites videos are streamed. which means that we do no just download 1 file, we download lots of small packages. In the dev-tools these packages can be traced. The website I'm interested in is : http://www.rtlxl.nl/# !/goede-tijden-slechte-tijden-10821/c8e2bff7-5a5c-45cb-be2b-4b3b3e866ffb.

  



  -The packages have a .TS extension.

  



  -Packages can be saved by copying the url of the request

  



  -I can not play these files.

  



  I must have done something wrong, or I'm missing something. I want to know what I am doing wrong. I want to create a chrome extension for personal use which captures the urls of all the packages. when I have all the urls I want to pass them on to a php scripts which downloads them and uses ffmpeg to paste them into a mp4 file.

  



  Please help me get the packages.

  


• Encoding of two full hd streams in Linux + GPU with Intel HD4000 / VA API / FFMPEG / OpenGL

  27 juin 2017, par qknight

  i want to encode/stream two full hd streams in realtime from my laptop to a remote location using linux/xorg on the host.

  VA API

  for this i’ve been playing with the VA API but the performance is pretty bad with 5.59 fps (see paste below).

  FFMPEG

  using ffmpeg with CPU encoding i get about 200 fps but then all cores of my Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz are busy and the fan turns on.

  future plans

  i want GPU support in encoding and later integrate this into a program which streams a virtual xorg ’screen’, see https://lastlog.de/wiki/index.php/Raspberry_PI_virtual_screen for more details on my plans.

  maybe h264 isn’t even what i want ? so if someone advices towards a different implementation, i’d welcome that.

  besides VA API there seems to be QuickSync but i didn’t experiment with that yet as it is not packaged on NixOS just yet.

  note : i need a library to have a smooth integration into the code.

• 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 ?
