iphone - Cocoa - Add Video Watermark General Info -

-

How to programmatically add a watermark or some type of overlay to video using a cocoa step by step (Although it would be terrible), but more or less is looking for where I should start learning how. Have the frameworks been developed to work for it? I would like to make some originals for cocoa or purpose-C or C because I would eventually like to go to the iPhone. Any help would be great.

I'm not sure whether you meant only for playback, or if you had a watermark

If you only mean for playback, you can probably add a scene on top of the player view on Mac and iPhone, which includes Watermarks < / P>

If you want a watermark on the video, then this is hard on the Mac And probably it is impossible on the iPhone without writing QuickTime

On the Mac, the code can look like this (you have to import QTKit): 

  // Make a new movie so that we do not destroy the existing one. QTMOVY * Movie = [[QTMOVY ALLOC] Init Vthmovia: Current Moody Timezone: QtMake timorange (QTMacTime (0,1000), [current duration period]) Error: zero]; // Make it editable [movie set: attribute: [nsnumber number for worldbuilds: yes] k: qtmovi additive attribute]; // Size NSValue * Value = [Movie Specialty Foreaki: QTMovieNaturalSizeAttribute]; NSSize size = [value value of value]; // Add a new track to the movie and add it to the top layer QTTrack * track = [movie addVideoTrackWithSize: size]; [Track set attribute: [NSNM number number short: -1]: QTtrackLayer Attribute]; // We create a codec dictionary about adding an image to the NS * image. Image = [Object] with the NSDictionary dictionary: "Tough", QATID image coded type, [NSNumber number with long: codec highwive], QATID image codequality, zero]; // Get the length of video in QT QTTime qttime = [currentMovie period] Speak; NSTEInterval Rifetime; QTGetTimeInterval (quetaim, and reftime); // Add image for the entire duration of the video [Track ADIMAGE: Duration for Image: Attributes with qttime: imageDict]; // Finally, tell this track that it should use its alpha right MediaHandler Media = GetMediaHandler ([[Track Media] QuickTimeMedia]; MediaSetGraphicsMode (Media, GraphicsSystemTerraFlafa, NULL);

... and this is it! There is now a watermark in your movie, and you can export it to the file.

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
