  curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

• How to fix ffmpeg complex filters "Invalid stream specifier" [duplicate]

  15 mai 2019, par Chase

  This question already has an answer here :

  • FFmpeg filter_complex concat gives only first input on crop

  • ffmpeg : chain of multiple filter_complex, re-using intermediate output stream
    
    1 answer
    

  I’m attempting to scale and blur (sections of) a video with ffmpeg complex filters. This has actually been working in production for years.

  I’m now running a newer build of ffmpeg on Ubuntu 18.04 and getting an error relating to the filters where the same command works fine on Ubuntu 16.04’s ffmpeg against the same video.

  
  Specifically, I’m seeing the following error :

  mov,mp4,m4a,3gp,3g2,mj2 @ 0x56055a5902c0] Invalid stream specifier: vs0.
  
      Last message repeated 1 times
  
  Stream specifier 'vs0' in filtergraph description ... matches no streams.

  Has something about the complex filter API changed that would make this same input invalid in a newer version of ffmpeg ?

  ---

  The command in question is just running the following in a Bash terminal.

  ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4

  If we break up the complex filter statement, it looks like :

  [0:v]scale=-2:'min(320,ih)'[vs0];
  
  [vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];
  
  [vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];
  
  [vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];
  
  [vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];
  
  [ovr1][b2]overlay=main_w/9:0[vs1]

  ---

  On ffmpeg version N-86980-g62b7553 (Ubuntu 16.04), everything works great as it has done for years.

  $ ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4

• How many "Ruby on Rails" sites can be hosted using sub url in apache configuration file on apache4 with passenger4 on Ubuntu server ?

  17 octobre 2013, par user1731249

  Server's Hardware config :
  Ubuntu server 12.04, CPU : dual code (64-bit), RAM : 8GB, Disk : 200GB.

  Server's Software config :
  Apache2, Passenger4, Rails4, ruby2, MySQL.

  I'm developing a Ruby on Rails website which performs following tasks.

  1. Upload a series of images as zip.
  2. Extract zip images to temp directory.
  3. Convert series of images to video using FFMPEG.
  4. updating video info in MySQL db
  5. Viewing the video in HTML5 video tag.

  Maximum length of single video being 1min and on an average there may be 50 videos to be converted per day. I created three copies (Don't ask me why !) of same website and hosting three sites as sub-URLs like "example.com" being the domain and example.com/site1, example.com/site2, example.com/site3. Below is the Apache configuration :
  RailsAutoDetect off

  ServerName 127.0.0.1

      DocumentRoot /home/ubuntuuser/work/public
  
      ErrorDocument 404 /404.html
  
  
  
  RailsBaseURI /site1
  
  
  
      <directory></directory>home/ubuntuuser/work/site1/advisor/public>
  
              Allow from all
  
      Options -MultiViews
  
              RailsEnv production
  
      
  
  
  
  RailsBaseURI /site2
  
  
  
  <directory></directory>home/ubuntuuser/work/site2/advisor/public>
  
              Allow from all
  
      Options -MultiViews
  
              RailsEnv production
  
      
  
  
  
      RailsBaseURI /site3
  
  
  
  <directory></directory>home/ubuntuuser/work/site3/advisor/public>
  
              Allow from all
  
      Options -MultiViews
  
              RailsEnv production
  
      

  How many such sites can I host with sub-URLs without big performance drag ?
  Also please help to do a performance test for all the sub-URLs.
