• Evolution #3865 (En cours) : URL ressources + compression CSS -> Cross-Origin Request Blocked

  24 novembre 2016, par denis -

  En ajoutant une URL ressouces, l’affichage des police ne fonctionne plus. Firebug me dit "Cross-Origin Request Blocked : The Same Origin Policy disallows reading the remote resource at http://medias.nova-cinema.org/squelettes/css/font-osp-din/osp-din-webfont.woff. (Reason : CORS header ’Access-Control-Allow-Origin’ missing)."

  Le problème se règle en rajoutant Header set Access-Control-Allow-Origin "*" dans le .htaccess comme indiqué ici http://connect.adfab.fr/developpement-front/utiliser-tous-les-verbes-http-avec-cors

• How do I skip audio 1 and transcode audio 2 to aac with ffmpg ? [closed]

  25 septembre 2024, par CA Opa

  I have videos with 2 audio tracks. Track 1 is ac3 foreign and track 2 is flac English. I only want to transcode the English track 2. When I use ffmpg to map track 2 and transcode to aac the result is vorbis.

  


  Here is my code :

  


  "ffmpeg.exe" -i "U:\infile.mkv" -map 0:v:0 -c:v:0 copy -map 0:a:1 -c:a:1 aac -ac:a:1 2 -b:a:1 192000 -map 0:s:0 -c:s copy "U:\Outfile.mkv"


  


  This is what happens :

  


    Stream #0:0(eng): Video: h264 (High), yuv420p(tv, bt709/unknown/unknown, progressive), 1278x720 [SAR 1:1 DAR 71:40], 23.98 fps, 23.98 tbr, 1k tbn (default)
  Stream #0:1(rus): Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s (default)
      Metadata:
        title           : Многоголосый закадровый, студия "Селена Интернешнл"
  Stream #0:2(eng): Audio: flac, 48000 Hz, stereo, s16

[out#0/matroska @ 000001b979895440] Codec AVOption b:a:1 (set bitrate (in bits/s)) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some decoder which was not actually used for any stream.
Stream mapping:
  Stream #0:0 -> #0:0 (copy)

  If I transcode both audio tracks it succeeds.

  


  "ffmpeg.exe" -i "infile.mkv" -map 0:v:0 -c:v:0 copy -map 0:a:0 -c:a:0 aac -ac:a:0 2 -b:a:0 192000 -map 0:a:1 -c:a:1 aac -ac:a:1 2 -b:a:1 192000 -map 0:s:0 -c:s copy "Outfile.mkv"


  


  If I just transcoding track 1 it works. Why does it fail when I only map audio track 2 ?

  


• 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
