  vaapi_encode_h265 : Improve profile support
  Set profile compatibility/constraint flags properly (including the
  
  constraint flags used for RExt profiles, as all streams we can currently
  
  generate are RExt-compatible), and use that to add support for the "Main
  
  Intra" and "Main 10 Intra" RExt subprofiles (for which we can re-use the
  
  existing Main and Main10 VAAPI profiles).

• How to trim and merge using Fluent FFMpeg ?

  29 juillet 2016, par John D.

  Here’s what I want to do with fluent-ffmpeg :

  I have 3 input files. An intro, main, and outro video. I wish to merge the three, while trimming the main video. Here is my code :

  var ffmpegCommand = ffmpeg();
  
  ffmpegCommand.addInput(introVideo);
  
  ffmpegCommand.addInput(mainVideo).seekInput(20).duration(3);
  
  ffmpegCommand.addInput(outroVideo);
  
  ffmpegCommand.on('error', function(err, stdout, stderr){
  
    console.log("FAILED!\n\t"+err+"\n\t"+stdout+"\n\t"+stderr);
  
  });
  
  ffmpegCommand.on('end', function(){
  
    console.log('COMPLETE!');
  
  });
  
  ffmpegCommand.on('start', function(commandLine) {
  
    console.log('Spawned Ffmpeg with command: ' + commandLine);
  
  });
  
  ffmpegCommand.mergeToFile('final.mp4', './vid_files/tmp');

  The program executes fine, but when I ffplay final.mp4, the result is that introVideo plays then the video appears to freeze. According to the fluent-ffmpeg documentation, it states "Each of these [Input options] methods apply on the last input added". So I can’t figure out why that syntax doesn’t seem to work...

  How can I trim the main video to send to mergeToFile ?

  Note that this works fine if I don’t have .seekinput(20).duration(3) on the second addInput.

  Oh, here’s the outputted commandLine value :

  ffmpeg -i ./vid_files/intro.mp4 -ss 20 -i ./vid_files/main.mp4 -i ./vid_files/outro.mp4 -y -filter_complex concat=n=3:v=1:a=1 -t 3 final.mp4

• Is there a locale that supports all symbols ?

  2 juin 2014, par user3698015

  I’m having this problem with ffmpeg basically this
  https://github.com/rg3/youtube-dl/issues/2999

  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. (or at least that’s what i’ve been thinking)

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

  Here’s one example
  as you may or may not be able to see, lots of symbols from seemingly everywhere.
  So which locale supports all the symbols, or at least as many as possible ?
  Also, is there a disadvantage to using a locale that’s not your native locale ?

  edit : i just remembered that in the past when i used a locale that wasn’t supported the symbol would appear as a questionmark in a box...

  but the triangle didn’t appear as that, it appeared as it was... so this is odd

  so i figured that i should give the error message precisely

  and this is what’s going on (everything)

  @echo off
  
  setlocal
  
  cd C:\youtube-dl
  
  
  
  set /p "var1=Enter URL: " %=% pause

  set "var2=%date:/=-%"

  second edit :
  http://www.fileformat.info/info/unicode/char/25c4/index.htm
  so i found the symbol but i’m having trouble in finding out how each locale relates to the symbol...

  Like what about each locale makes the symbol usable to cmd ?

  third edit :
  worse come to worse and there is no locale that supports all unicode characters, or to do what i want it to,
  These are the unique characters that i’ve identified and have problems with right now,
