• XDCam EX gets some friends

  21 octobre 2009

  Sony has announced a couple new additions to the XDCamEX family - the PMW-350 and the PMW-EX1R.

  The 350 is a shouldermount camera with interchangeable lenses and 2/3" chips. That puts it somewhere between the 1/2" PDW-F355 and the 2/3" 4:2:2 PDW-700.

  

  The EX1R is a minor bump to the EX1, adding features that users have asked for, like a dedicated viewfinder and a DVCam recording mode.

  For me, the most interesting bit of news is that Sony is launching the "MEAD-MS01," an SXS to MemoryStick adapter. I guess Sony noticed that many EX1 and EX3 users have been using SD adapters, and decided to get into that market. And of course, they had to use everyone’s least favorite flash format, Memorystick. I’ll stick to my SD cards for now, but it’s nice to see Sony "legitimize" that recording option a bit.

• change output order of FFprobe

  28 avril 2023, par summerrain

  How can I change the output order of FFprobe ?

  


  ffprobe -hide_banner -show_streams -show_format space.mkv -of json=c=0 -o output.json creates a json output file with the streams sections first and the format section last.

  


  I need the reverse order (format section first, streams section last).

  


  But reordering the parameters (i.e. -show_format -show_streams) has no effect unfortunately.

  


  This is the output of the command above :

• Imagick refresh

  25 septembre 2013, par 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.
