  • How can I send images to x264 one by one?

    - by Ole Jak
    I've got an image generator written in C. Now I want to pass those images to x264 to encode them and write it to a file. Every 100th image should be a key frame in order to save the video to disk every 100th frame. The image generator calls onImageGenerated() after each image. I'd appreciate any pointers on how to set up x264 in this way.

  • join same rails models twice, eg people has_many clubs through membership AND people has_many clubs through committee

    - by Ben
    Models: * Person * Club Relationships * Membership * Committee People should be able to join a club (Membership) People should be able to be on the board of a club (Committee) For my application these involve vastly different features, so I would prefer not to use a flag to set (is_board_member) or similar. I find myself wanting to write: People has_many :clubs :through = :membership # :as = :member? :foreign_key = :member_id? has_many :clubs :through = :committee # as (above) but I'm not really sure how to stitch this together

  • Why is the Java VM so popular?

    - by sdudo
    There are more and more programming languages (Scala, Clojure,...) coming out that are made for the Java VM and are therefore compatible with the Java Byte-Code. I'm beginning to ask myself: Why the Java VM? What makes it so powerful or popular that there are new programming languages, which seem gaining popularity too, created for it? Why don't they write a new VM for a new language?

    - by Kevin Brown
    I need to track the completion of tasks for users. I started by having a row called "first_login", "profile_complete", "other_thing_complete", etc... I'd like to combine these all into one row "activity_state". I just don't know how to properly store data in this field, and how to retrieve it. What kind of field should it be, and how should I read/write to it?

  • Would Python make a good substitute for the Windows command-line/batch scripts?

    - by Lawrence Johnston
    I've got some experience with Bash, which I don't mind, but now that I'm doing a lot of Windows development I'm needing to do basic stuff/write basic scripts using the Windows command-line language. For some reason said language really irritates me, so I was considering learning Python and using that instead. Is Python suitable for such things? Moving files around, creating scripts to do things like unzipping a backup and restoring a SQL database, etc.

    - by orano10000
    Basically I have a navbar and a title, that both have the properties, position: fixed; top: (VALUE I INSERTED); My problem is that obviously when I write the main body of the document the text is underneath the title/navbar. I need to get the text to be underneath the title and navbar, but without it having a fixed position. If any more information with code is needed, just comment saying so. Thanks in advance.

  • How to determine whether or not a video format is supported

    - by Tal Even-Tov
    Hi, I've had to write an application that lists and plays tutorial videos along with accompanying text. It works well but since the videos are added by the user I need a way of checking to see whether or not a video can be played on the machine. I'm not sure whether or not there is an easy way to try test the file (and catch errors) or if I need to start looking at codecs installed. Does anybody have any experience with this?

  • Can I create a cross-project source reference in redmine?

    - by UlfR
    If you have two separate projects that is somehow connected. How can one make a reference to the source of the other project? For referencing the source of your own project you use: source:some/file But since I want to refer to code in another project my thought was that I could write something like: other_project:source:some/file Anyone that knows if this is possible in some way? I have read http://www.redmine.org/wiki/redmine/RedmineTextFormatting#Redmine-links but found no clues there.

    - by George0x77
    I am just wondering if you are supposed to write a sort of really secure application with data being transmitted over insecure networks, what kind of encryption algorithm will you use it in order to make it safe ?

Please provide your ideas and suggestions. Thank you.

Thanks, R.
