• download compressed video from m3u8 link

  6 juin 2020, par alsaibi

  i'm making a python script to download videos from a site

  



  it's working perfectly but some videos are m3u8

  



  the links are something like this

  



  https:\/\/dl.v.vrv.co\/evs\/5e915ac2127515861ea2563ca4e3eb25\/assets\/jpy1j4wghs4eepk_,1605371.mp4,1605379.mp4,1605363.mp4,1605355.mp4,1605347.mp4,.urlset\/master.m3u8?Policy=eyJTdGF0ZW1lbnQiOlt7IlJlc291cmNlIjoiaHR0cCo6Ly9kbC52LnZydi5jby9ldnMvNWU5MTVhYzIxMjc1MTU4NjFlYTI1NjNjYTRlM2ViMjUvYXNzZXRzL2pweTFqNHdnaHM0ZWVwa18sMTYwNTM3MS5tcDQsMTYwNTM3OS5tcDQsMTYwNTM2My5tcDQsMTYwNTM1NS5tcDQsMTYwNTM0Ny5tcDQsLnVybHNldC9tYXN0ZXIubTN1OCIsIkNvbmRpdGlvbiI6eyJEYXRlTGVzc1RoYW4iOnsiQVdTOkVwb2NoVGltZSI6MTU5MTU1ODg4Nn19fV19&Signature=S7bDaUsOAplp437a-2hBIiED-jgwGCHups-cCHFK0etbVwn5O0Lx09~yiPvOnL9kae3AHFbPnlduxwotDDzKUMy01Swbudjz~HLwR26Lp1fb1vKAhZDgM1LJPkBFuQSbCYfN4cKG2aihTfbxNy3S63sUdQJouVjxwgkIj069kIjTmj7GsMfFgqrvYZja~RUOvF7n4evA0iisKbzTio4gB3gGYBhqOe~rh1rSbqGsO92U1AiflVGETpgo~z0p89agQGK4LHamKEWQUF2vITqYA2WXKYV1qNNg5JJ3ZDJUp3L3qE2zCBige1qw9UYtxr7jvg-PhZh4Esr07xS5G7UfQA__&Key-Pair-Id=DLVR


  



  i'm trying to download mp4 or mkv file to watch the video offline

  



  i tried using ffmpeg and youtube-dl

  



  they only work after changing \/ in the link to //

  



  ffmpeg command i used ffmpeg -i "Link" -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 file.mp4

  



  that's not the problem

  



  they download the full raw video file which is around 1.5GB

  



  but in the site watching the video take maximum 250MB at highest quality

  



  and the download is really slow for some reason

  



  it take almost 1 hour to download 1 video

  



  and at the end video don't open after finish downloading

  



  vlc say it's corrupted

  



  isn't there is a way to convert the link to direct link to compressed file link ?

  



  the site take 200MB to watch the video and loading the video is fast but downloading it from the link above take 1.5GB and it's soo slow

  


• Why do I use the header file/library + ffplay.c download from the official website of ffmpeg to make the player worse than the official ffplay ?

  15 juillet 2020, par fredirty2017
  


  1. I am use win10 system with a "http_url_mp4" in hand, the MIME of this file is :
video/mp4 ; codecs="mp4a.40.2,avc1.640020" ; profiles="isom,mp41,mp42".

     


  


  2. I downloaded the header files, libraries, dlls, source code from https://ffmpeg.zeranoe.com/builds/ ,then :

     


  


  3. Run offical "ffplay http_url_mp4", audio and video viewing is normal ;

     


  


  4. I used VS2017 (the project has no special settings) to compile and link the fftools/ffplay.c，fftools/cmdutil.c and the included header files(libavcodec/libavutil and so on), libraries(such as avcodec.lib, avdevicelib, etc.), dlls(avcodec-58.dll / avformat-58.dll...), then run "myffplay http_url_mp4", The playback is stuttering, debugging found av_read_frame relative The processing cost more time, the calling frequency will be lower.

     


  


  5. i found config.h only line '#define FFMPEG_CONFIGURATION "—enable-gpl"', but offical ffplay cmdline shows :
'—disable-static —enable-shared —enable-gpl —enable-version3 —enable-cuda —enable-cuvid —enable-d3d11va —enable-dxva2 —enable-libmfx —enable-nvenc —enable-avisynth —enable-bzlib —enable-fontconfig —enable-frei0r —enable-gnutls —enable-iconv —enable-libass —enable-libbluray —enable-libbs2b —enable-libcaca —enable-libfreetype —enable-libgme —enable-libgsm —enable-libilbc —enable-libmodplug —enable-libmp3lame —enable-libopencore-amrnb —enable-libopencore-amrwb —enable-libopenh264 —enable-libopenjpeg —enable-libopus —enable-librtmp —enable-libsnappy —enable-libsoxr —enable-libspeex —enable-libtheora —enable-libtwolame —enable-libvidstab —enable-libvo-amrwbenc —enable-libvorbis —enable-libvpx —enable-libwavpack —enable-libwebp —enable-libx264 —enable-libx265 —enable-libxavs —enable-libxvid —enable-libzimg —enable-lzma —enable-zlib',

     


  


  6. Does the VS project need special settings or other codes ?

     


  


  


• youtube-dll won't download live stream

  26 juillet 2020, par NFC

  I'm trying to download a livestream in ubuntu 14 using youtube-dl but it will not download. I'm using the latest version of youtube-dl. Using Nasa channel as an example, here are the steps that I'm following

  


  1) youtube-dl —list-formats https://www.youtube.com/watch?v=21X5lGlDOfg

  


  2) youtube-dl -f https://www.youtube.com/watch?v=21X5lGlDOfg (also tried youtube-dl )

  


  The download hangs at roughly 512kb for hours. Is anyone able to successfully download the content ? Am I doing anything wrong ?
