• Android - Choosing between MediaRecorder, MediaCodec and Ffmpeg

  15 mars 2017, par Rohan Stark

  I am working on a video recording and sharing application for Android. The specifications of the app are as follows :-

  • Recording a 10 second (maximum) video from inside the app (not using the device’s camera app)
  • No further editing on the video
  • Storing the video in a Firebase Cloud Storage (GCS) bucket
  • Downloading and playing of the said video by other users

  From the research, I did on SO and others sources for this, I have found the following (please correct me if I am wrong) :-

  The three options and their respective features are :-

  1.Ffmpeg

  • Capable of achieving the above goal and has extensive answers and explanations on sites like SO, however
  • Increases the APK size by 20-30mb (large library)
  • Runs the risk of not working properly on certain 64-bit devices

  2.MediaRecorder

  • Reliable and supported by most devices
  • Will store files in .mp4 format (unless converted to h264)
  • Easier for playback (no decoding needed)
  • Adds the mp4 and 3gp headers
  • Increases latency according to this question

  3.MediaCodec

  • Low level
  • Will require MediaCodec, MediaMuxer, and MediaExtractor
  • Output in h264 ( without using MediaMuxer for playback )
  • Good for video manipulations (though, not required in my use case)
  • Not supported by pre 4.3 (API 18) devices
  • More difficult to implement and code (my opinion - please correct me if I am wrong)
  • Unavailability of extensive information, tutorials, answers or samples (Bigflake.com being the only exception)

  After spending days on this, I still can’t figure out which approach suits my particular use case. Please elaborate on what I should do for my application. If there’s a completely different approach, then I am open to that as well.

  My biggest criteria are that the video encoding process be as efficient as possible and the video to be stored in the cloud should have the lowest possible space usage without compromising on the video quality.

  Also, I’d be grateful if you could suggest the appropriate format for saving and distributing the video in Firebase Storage, and point me to tutorials or samples of your suggested approach.

  Thank you in advance ! And sorry for the long read.

• Developing a multi-tool video & audio program

  14 février 2019, par Risviltsov

  I’m in the middle of the Microsoft TEALS Java program, and we’ve just done a picture editor. I got an idea to develop a multi-tool program that edits video and audio programs professionally for those who can’t afford $2,000 in editing programs but demand all the tools. I’ve ran into a brick wall with the planning :

  What tools should I put in it ? I want this program to have most, if not all possible ways to change media files (as if I was to combine programs like Audacity, a lot of Adobe programs, etc.)

  I’m learning up FFMPEG and AWT, but I really want to tackle this project’s planning this year, to tackle on the programming in the next two years independently. Yay straightforward freeware* & too much time !

  (I don’t think this post belongs here, but I’m in search of help for I have no budget nor any help [it’s going into culinary])

  Thanks for your time.

• Official Debian Package for Piwik now available

  15 avril 2014, par Matthieu Aubry — Community, Meta

  We are excited to announce the release of Piwik package for Debian based linux distributions !

  There are several ways to use Piwik :
  
   Download and upload to your server
  
   or use 1-click Piwik installers
  
   or use Microsoft web app gallery
  
   or buy Piwik Cloud
  
   or as of today, you may get Piwik using our Debian package

  What are the benefits of using Debian package over direct download ?

  For some system administrators, using Debian package is an easier alternative than directly downloading the code. It allows sysadmins to deploy Piwik within seconds using “apt-get install piwik -V”.

  How do I install Piwik using official debian package ?

  The package supports Apache and Nginx web servers. Read the documentation at debian.piwik.org.

  Do I have to use the Debian Package on my debian system ?

  No, you may still want to use Piwik using the direct download approach. You can keep Piwik upgraded quite easily using the popular 1-click automatic update.

  How do I report a bug or feedback ?

  Create a ticket on the Github project Issues page.

  Will the debian repository be maintained in the future ?

  Yes, Aurélien Requiem (github) along with the Piwik team are committed to maintain the Debian Piwik repository in the future.

  Thank you to Aurélien for his great work on preparing, testing, and maintaining the Debian repository for Piwik.
