• Run ffmpeg command based on data on a file

  1er octobre 2019, par Jake Pearson — ffmpeg

  I have a text file which is generated as the output of a command.

  The text file has name of a file followed by all the matching audio tracks in one line, then the next line has the next video followed by matching tracks.

  Because some of the videos have less tracks and some have more, is there a way I can do if and else command for ffmpeg to do the mergeing based on number of tracks matched to the name ?

  This is the command I use to merge.

  Merge (Keeps Original files and makes a new one using them as the output)

  ffmpeg -i video.mxf_V1.MXF.m2v -i video.mxf_A1.MXF -i video.mxf_A2.MXF -c copy out.mxf

  followed by :

  ffmpeg -i out.mxf -map 0:0 -map 0:1 -map 0:1 -c copy finished.mxf

  Below is the example of how the file names are and how its written in the text file

  "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_V1.MXF.m2v" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A1.MXF" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A2.MXF" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A3.MXF" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A4.MXF" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A5.MXF" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A6.MXF" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A7.MXF" "5f367f72-9e2f-4f89-b3d6-2cdafed17d94_IRR_DOCUI_SONG_SomeMusic_KomKom.mxf_A8.MXF" 

  There’s about 25,000 lines of these.

  Another thing I wanted is to be able to name the final file the same as the video file.

• Introducing the Piwik Java Tracker – Analytics for your Java based applications

  18 novembre 2015, par Brett — Community, Development

  Hello Piwik Community !

  My name is Brett Csorba, a Software Engineer out of the US. I’d like to introduce the Piwik Java Tracker project, an easy way to track usage data within your Java applications !

  When would I need to track users in a Java application ? What’s wrong with front end tracking ?

  Absolutely nothing ! We encourage users to track information where it makes the most sense for them ! But in cases where

  • you have a 100% Java based application
  • you expose a REST layer where users can bypass your front end tracking code
  • you have valuable data you want to track that is unnecessary or too sensitive to pass back to the user

  the Piwik Java Tracker can help you track the data you need.

  What exactly can it track ?

  We aim to provide the full Tracking HTTP API. If you find we’ve left something out by mistake, let us know !

  You’ve sparked my curiosity, how would I use such a thing ?

  Well, once you’ve installed Piwik and set up your first website, you can grab the latest jar and include it in your project. The dependencies needed to both use and test this library can be found here.

  This library is intended to be used for projects that support Java 8. The released binaries are built, tested, and deployed from Oracle JDK 8.

  Using this API is as simple as creating a new request

  PiwikRequest request = new PiwikRequest(1, new URL("http://my-site.com/action")) ;

  Setting some more information if you want to

  request.setActionName("myAction") ;
  request.setPageCustomVariable("key", "value") ;

  and firing the request.

  PiwikTracker tracker = new PiwikTracker("http://your-piwik-domain.tld/piwik.php") ;
  HttpResponse response = tracker.sendRequest(request) ;

  Check out this guide to using the API for some more information !

  Looks cool so far, can I help out ?

  Yes ! Absolutely ! Download the project, try it, break it without mercy ! (Just make sure you tell us how.) Contribute to the project or let us know what we can do to it to improve it. As with all open source projects, we need your help to improve it.
