• Creating personalized video from user submitted pictures and data

  18 décembre 2016, par Rajat Singhal

  Can someone guide me towards what technology to use to create personalized video from user submitted pictures and data.. The process has to be automated, as in server must be able to create a downloadable video from photos and text submitted by user..

  So the process will probably be like one video will be created by a hired artist, with placeholders where the user submitted pictures and text will fit in. Now with user submitted data video can be created and downloaded from the website..

  An example can be the videos created by facebook now-a-days on your birthday or year end. They consist some of your photos, some text and have a common video theme.. You can view one here http://newsroom.fb.com/news/2016/12/facebook-2016-year-in-review/

  One way I’ve found is to write the video code in html5 and then record it with phantomjs and ffmpeg.. http://mindthecode.com/recording-a-website-with-phantomjs-and-ffmpeg/

  But it seems a bit unnatural way of doing it.. And also I think not a lot of good artists are out there who can create the video theme in html5..

• Fix description of —rice-partition-order in flac -H

  9 janvier 2016, par Thomas Zander

  Fix description of —rice-partition-order in flac -H
  This is more of a "human language versus programmer parlor" issue.
  
  src/flac/main.c will return usage error for an argument greater
  
  than FLAC__MAX_RICE_PARTITION_ORDER (15u).
  
  While in programming "0..16" usually means "from zero to 15", in
  
  natural human-to-human talk, it would rather mean "from zero to 16".
  
  This changes the wording a bit to avoid this misunderstanding.

• Dissappearing characters in youtube-dl, ffmpeg, and windows

  4 juin 2014, par user3407161

  so what happens is that if the video title has a symbol that isn’t supported by your current locale then ffmpeg won’t be able to get to that file properly.

  Here’s one example

  ►2 HOURS BEST MELODIC DUBSTEP MIX APRIL 2013◄ ヽ( ≧ω≦)ﾉ

  as you may or may not be able to see, lots of symbols from unicode.

  The problem is that in cmd and ffmpeg, though cmd can see

  ►2 HOURS BEST MELODIC DUBSTEP MIX APRIL 2013◄ ヽ( ≧ω≦)ﾉ

  ffmpeg only sees

  2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ

  This is the exact error message (i’m using youtube-dl)

  [ffmpeg] Adding metadata to 'C:\Music\ToBeDone\2014-06-01\►2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013◄ ヽ( ≧ω≦)ﾉ.mp4'
  
  ERROR: C:\Music\ToBeDone\2014-06-01\2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ.mp4: No such file or directory
  
  ERROR: WARNING: unable to obtain file audio codec with ffprobe

  After some research i’ve determined that by changing the system locale you can change which symbols cmd can support.

  However

  ヽ

  Used to appear as a box in a question mark in United states locale. In japanese locale it appears as it does on your screen right now.

  the problem with

  ◄

  is that even though it’s not appearing as a question mark in a box (it’s appearing as how it should be), ffmpeg (or cmd) can’t detect it properly.

  (Refer back to the error message, i’ll repost it below.)

  [ffmpeg] Adding metadata to 'C:\Music\ToBeDone\2014-06-01\►2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013◄ ヽ( ≧ω≦)ﾉ.mp4'
  
  ERROR: C:\Music\ToBeDone\2014-06-01\2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ.mp4: No such file or directory
  
  ERROR: WARNING: unable to obtain file audio codec with ffprobe

  So as you can see, I think cmd passed on the symbol correctly to ffmpeg seeing from the adding metadata line, but when it actually does the operation ffmpeg loses

  ► and ◄

  Could this be a bug with ffmpeg ? MY workaround so far with incompatible symbols was to change the system locale, but I don’t think i can do that with these two symbols...

  These are the unique characters that i need to have a locale that supports
