• Nomenclature #4519 (Nouveau) : Renommage de terminologie (blacklist / whitelist)

  13 juillet 2020

  En lisant la compilation [PHP Annotated – June 2020](https://blog.jetbrains.com/phpstorm/2020/06/php-annotated-june-2020/) on tombe sur ce point :

  [[RFC] Change terminology to ExcludeList](https://wiki.php.net/rfc/change-terminology-to-excludelist) — The topic of renaming offensive terms has not been overlooked by the PHP world either. There have been [heated discussions](https://externals.io/message/110515) in the Internals.
  In the PHP core, the change affects only one thing : the configuration directive `opcache.blacklist_filename` should be renamed to `opcache.exclude_list_filename`.
  Many other PHP tools have already made changes in this regard : [PHPUnit](https://github.com/sebastianbergmann/phpunit/blob/master/ChangeLog-9.3.md#930---2020-08-07), [Drupal](https://www.drupal.org/project/drupal/issues/2993575), [Xdebug](https://github.com/xdebug/xdebug/commit/63b43b51e43b794cf8cd740e54089b2b7320fbe1), [Yii](https://github.com/yiisoft/yii2/pull/18104), [Composer](https://github.com/composer/composer/pull/8957) (+ [working with non-master Git branches](https://blog.packagist.com/composer-and-default-git-branches/)).

  C’est certainement intéressant aussi de songer à ces renommages chez nous également, utilisés à quelques endroits.

• how to check the number of duplicated frame for video 1sec ( about 30frames ) from video start and want to apply this for mpdecimate

  20 octobre 2018, par cool jobs

  How to check the number of duplicated frame for video 1sec ( about 30frames ) from video beginning point ? I want to apply this for mpdecimate with audio. Some videos have three duplicated frames, some videos - 15 duplicated frame, some videos have 19 duplicated frames.. so it looks I need a variable or math operator in ffmpeg as expression.

  1. some video have duplicated frames at beginning point , but it is
     not same always the number of duplicated frames.
  2. if get back variable which is for the number of duplicated frames
     from step-1 then split and trim apply mpdecimate with audio as
     much as step-1 variable returned, finally do concatenate each other.

  Is this possible with -filter_complex for one line ffmpeg command ?

• Vertical video play does not sync with multiple stacked video

  5 novembre 2018, par Sabha

  I dont know if I have wrote the subject well and if that can be understood. Nevertheless, here is an explanation

  I have 7 videos of different dimensions where the width is same (1080). I wish to place them one below the other to get a full hd vertical video (1080x1920). I tried the -filter_complex vstack filter in ffmpeg and got all the videos aligned one below the other and I am getting a perfect 1080x1920 full hd vertical video but they dont sync with each other. Once the videos are in sync, I need to put an audio too which should also sync with the in-sync video that will be made.

  There is so much of complexity. Please advice how do I make them sync. Is there any software that can allow me to put 7 videos one below the other in a timeline ? (if not 7, atleast 3-4 videos). Please advice where and how to start.

  Is there any option in Adobe Premier or any other software ?

  Thanks

  EDIT : I am doing a very long procedure to combine all 7 videos vertically

  first i use

  ffmpeg -i video1.mp4 -i video2.mp4 -preset veryslow -filter_complex vstack video12.mp4

  and then

  ffmpeg -i video12.mp4 -i video3.mp4 -preset veryslow -filter_complex vstack video123.mp4

  so on and so forth

  Is there a better way to do it all in one command ?
