• Imagick refresh

  25 September 2013, by Mikko Koppanen — Imagick

  After some hiatus I’ve been getting back on fixing bugs on Imagick and getting the code into more representable condition. This hiatus has been a result of busy work schedule and getting a new start-up running in Kuala Lumpur.

  While fixing a bug related to clone keyword I came across the following resource: http://www.rubblewebs.co.uk/imagick/. The page contains quite a nice collection of Imagick operations and is definitely worth checking out.

  On the other news, the development has been moved to Github. As I’ve been the most active developer of Imagick in the past years I decided to move the code to Github where rest of my projects are located: https://github.com/mkoppanen/imagick. For the past few days there has been quite a lot of development, mainly working on removing the excessive use of macros in the code to make things more readable and debuggable. This might be a good place to give thanks to Remi for fixing quite a lot of compile warnings and raising bugs regarding Fedora Packaging Policy. Most likely there will be a couple of beta releases in the near future.

  As mentioned in the previous post Windows builds are now available via http://windows.php.net and my builds provided here should be considered obsolete.

• FFmpeg for automatic video generation from images?

  22 January 2018, by Dionisis K

  I want to implement an automatic video generation from images, like facebook’s anniversary video. And I would also like to add some filters. I’ve been searching a lot and read FFmpeg’s documentation which is pretty amazing.

  In the future I want to have 10-20 "bashscripts" with different filters leading to different themes (e.g. fade-in, zoom, overlay images, left-to-right, etc..)

  So my biggest concern is having an interface which offers readable code and provides scalability. Since ffmpeg is a bashscript i searched for a wrapper

  There are wrappers in

  • https://github.com/PHP-FFMpeg/PHP-FFMpeg for php ,which doesn’t support image convertion to videos and complex filters .
  • https://github.com/fluent-ffmpeg/node-fluent-ffmpeg which looks promising but also difficult to go with complex filters
  • and https://github.com/kkroening/ffmpeg-python for python.I think that it s pretty good

  Are there any other wrappers worth to check ?
  Would you recommend something from the above ?
  Is there any pros and cons using a specific programming language for this particular case?
  Is there anything else i should bear in mind before I make a decision?

• Seekbar not working in Chrome

  9 January 2014, by mbajur

  I have encoded my video with the following settings chain:

  # line breaks are just for better readability
  
  ffmpeg -y -i /path/to/destination.mp4 
  
         -vcodec libx264 
  
         -acodec libfaac 
  
         -s 640x360  
  
         -movflags faststart  
  
         -aspect 1.7777777777777777 
  
         /path/to/source.mp4

  And, for some reason, it broken the ability to use seekbar in Google Chrome (it works good in Safari). What i have noticed is that the videos were working fine when there is no -movflags faststart setting in above chain. Here is an example of video, which is not working:

  Please note: Seekbar is not working when video download is in progress or it's 100% the first time. If video has been downloaded by chrome player and you refresh the page, seekbar works fine.
