• youtube-dl, is there a way to extract the "specific format" video URL ? [closed]

  29 juillet 2020, par karma

  Following my question before in this link,
  
It seems that the copied version is from the highest resolution format, as the resulting video portion is 1920x1080 resolution.

  


  The available format :

  


  C:\Standalone Program\YoutubeDL>youtube-dl -F https://www.youtube.com/watch?v=kGDgGsrA78s
[youtube] kGDgGsrA78s: Downloading webpage

  So after I do :

  


  youtube-dl -g https://www.youtube.com/watch?v=kGDgGsrA78s


  


  and the video URL result :

  


  https://r2---sn-uigxxi0ujipnvo-q2ne.googlevideo.com/videoplayback?expire=1596034295&ei=lzghX6SHKMOD8QPlx5SQBw&ip=223.255.228.87&id=o-AK6cYo88zJXe5Xb4y1QsXspuRnVCy-zPFpMaHcAaTQ-_&itag=137&aitags=133%2C134%2C135%2C136%2C137%2C160%2C242%2C243%2C244%2C247%2C248%2C278&source=youtube&requiressl=yes&mh=DA&mm=31%2C29&mn=sn-uigxxi0ujipnvo-q2ne%2Csn-npoe7nlz&ms=au%2Crdu&mv=m&mvi=2&pl=24&initcwndbps=173750&vprv=1&mime=video%2Fmp4&gir=yes&clen=456970484&dur=1389.955&lmt=1521825834085900&mt=1596012582&fvip=5&keepalive=yes&fexp=23883098&c=WEB&sparams=expire%2Cei%2Cip%2Cid%2Caitags%2Csource%2Crequiressl%2Cvprv%2Cmime%2Cgir%2Cclen%2Cdur%2Clmt&sig=AOq0QJ8wRgIhAMvZrHYvC1YrkvtARzhjyD8dnMnlefobGrOFM1rX6QZPAiEAqqeIsKdZ19y-SlHf-l8YwTx2yYbo1p5sFlVoC87oXEQ%3D&lsparams=mh%2Cmm%2Cmn%2Cms%2Cmv%2Cmvi%2Cpl%2Cinitcwndbps&lsig=AG3C_xAwRAIgAIwAVMPrcMhAL476uN_ZzWj8vKPGGW58KCpHBYBsKeICICRgVWgthNvgbGl8VgQwscjJ0n8ib4XBNjRxRgSg2T5r&ratebypass=yes


  


  I think the URL is for :

  


  137          mp4        1920x1080  1080p 4443k , avc1.640028, 30fps, video only, 435.80MiB


  


  Since I want a smaller file size, I wonder if it's possible to get the video URL (for example) for :

  


  243          webm       640x360    360p  420k , vp9, 30fps, video only, 60.81MiB


  


  So then later when I feed the URL to ffmpeg to extract some portion of that lower quality video URL, the result has a smaller file size.

  


  Any kind of help would be greatly appreciated.
Thank you in advanced.

  


  BTW, I use Windows 10 command prompt (administrator).

  Overview : Class 1-A visits Nabu Island where they finally get to do some real hero work. The place is so peaceful that it's more like a vacation … until they're attacked by a villain with an unfathomable Quirk ! His power is eerily familiar, and it looks like Shigaraki had a hand in the plan. But with All Might retired and citizens' lives on the line, there's no time for questions. Deku and his friends are the next generation of heroes, and they're the island's only hope.

  


• What is this "fixing the build scripts" for compiling x264 ?

  29 mai 2020, par Blake Senftner

  I am trying to compile an all static build of source-customized ffmpeg libraries with the additional codecs from VideoLAN, such as their x264 codec. I am ultimately building for use in Windows with Visual Studio 2015 C++, so I am comparing a few compiling guides for my instructions.

  



  In the guide linked below (I located via Google searches) shows how to compile x264 with the VS2015 toolchain in MSYS2 without any special steps :
https://gist.github.com/RangelReale/3e6392289d8ba1a52b6e70cdd7e10282

  



  While in this other guide, offered by the compiling guide pages from ffmpeg's web site, it includes steps for "fixing the build scripts" for x264 :
https://www.roxlu.com/2019/062/compiling-ffmpeg-with-x264-on-windows-10-using-msvc

  



  Problem being, when I "fix the build scripts" the configure script no longer finds a C compiler. Building with the first guide seems to work, but it was also written nearly 2 years ago, so perhaps the ffmpeg guide is doing some important fix ? I don't know.

  



  I am :

  



  

  1. Running a "VS2015 x64 Native Tools Command Prompt"

  


  2. launching a pacman loaded msys2 shell via "msys2_shell.cmd -mingw64 -use-full-path"

  


  3. git cloning http://git.videolan.org/git/x264.git

  


  



  and at this point the two compiling guides vary, the first guide just cd's into x264 and runs configure while the other guide does some curl download of a config.guess file and then some sed manipulation of ./configure. Considering these instructions are "endorsed" by the ffmpeg site, I am left wondering what that is doing and how critical is it that these "special" steps cause my x264 configure to fail.
