• FFmpeg command to capture Audio from Android mobile

  24 novembre 2023, par Uday

  I'm trying to capture Audio from my Android mobile using FFmpeg.
Tried the below commands and the recorded clip has no Audio in it, it's just a dark black screen with no audio/video.

  


  Basically, I want to stream the live microphone audio to the RTSP server

  


  Given all Android permission for the microphone & camera.

  


  Lib used : ffmpeg_kit_flutter

  


  Here are the commands which I tried :

  


   FFmpegKit.execute('-y -f android_camera -i 0:1 -r 30 -c:a aac -f rtsp -rtsp_transport tcp "$Url"');


  


  Command :

  


  FFmpegKit.execute('-y -f android_camera -i 0:1 -r 30 -c:a libmp3lame -qscale:a 2 "/storage/emulated/0/Download/androidvideo.mp3"');

FFmpegKit.execute('-y -f android_camera -i 0:0 -r 30 -c:a wavpack -b:a 64k "/storage/emulated/0/Download/androidvideo.wav"');


  


  This command records video but no audio in it

  


  FFmpegKit.execute('-video_size hd720 -f android_camera -camera_index 1 -i anything -r 10 -t 00:00:15 "$dir/androidvideo.mp4”');

• FFmpeg command to capture video/Audio from Android mobile

  17 juillet 2023, par Uday

  I'm trying to capture Vido/Audio from my Android mobile using FFmpeg.
Tried the below commands and the recorded clip has nothing in it, it's just a dark black screen with no audio/video.

  


  Actually, I wanted to recode the audio from Android Mobile.
Any Idea what's wrong with this command ?

  


  Given all Android permission for the microphone & camera.

  


  Lib used : ffmpeg_kit_flutter

  


  Command :

  


  FFmpegKit.execute('-y -f android_camera -i 0:0 -r 30 -c:v mpeg4 -f mp4 "/storage/emulated/0/Download/androidvideo.mp4"');

FFmpegKit.execute('-y -f android_camera -i 0:0 -r 30 -pixel_format bgr0 "/storage/emulated/0/Download/androidvideo.mp4"');


  


  This command records video but no audio in it

  


  FFmpegKit.execute('-video_size hd720 -f android_camera -camera_index 1 -i anything -r 10 -t 00:00:15 "$dir/androidvideo.mp4”');

• To all Matomo plugin developers : Matomo 5 is coming, make your plugin compatible now

  5 mai 2023, par Matomo Core Team — Development

  We’re planning to release the first beta of Matomo 5 in a few weeks. For making it easy for Matomo users to be able to upgrade to this beta, it would be great to have as many plugins on the Marketplace as possible already updated and compatible with Matomo 5. Then many users would be able to upgrade to the first beta without any issues.

  Presumably, as you put your plugin on our Marketplace, you want people to use it. Making your plugin compatible with Matomo 5 helps ensure that people will be able to find and keep using your plugin. If your plugin is not compatible with Matomo 5, your plugin will be automatically deactivated in Matomo 5 instances. We’ll be happy to help you achieve compatibility should there be any issue.

  How do I upgrade my Matomo instance to Matomo 5 ?

  If you have installed your Matomo development environment through git, you can simply checkout the Matomo 5 branch “5.x-dev” and install its dependencies by executing these commands :

  • git checkout 5.x-dev
  • composer install

  Alternatively, you can also download the latest version directly from GitHub as a zip file and run composer install afterwards.

  How do I upgrade my plugin to Matomo 5 ?

  • We recommend you create a new branch for your plugin that supports Matomo 5. For example a branch named “5.x-dev“. This way you will be able to make changes to your plugin for Matomo 4 and Matomo 5 and release separate versions.
  • Check out our migration guide from Matomo 4 to Matomo 5 and make sure to review the list of all breaking changes.
  • Release a new version of your plugin in GitHub as usual.

  While there are some breaking changes in Matomo 5, most of our Platform APIs remain unchanged, and almost all changes are for rarely used APIs. Quite often, making your plugin compatible with Matomo 5 will just be a matter of adjusting the “plugin.json” file (as mentioned in the migration guide).

  You can find all developer documentation on our developer zone which has already been updated for Matomo 5.

  How do I know my plugin changes were released successfully ?

  If you have configured an email address within your “plugin.json” file, then you will receive a confirmation or an error email within a few minutes. Alternatively, you can also check out your plugin page on the Marketplace directly. If the plugin release was successful, you will see additional links below the download button showing which versions your plugin is compatible with.

  

  How can switch between Matomo 4 and Matomo 5 or downgrade to Matomo 4 ?

  To downgrade from Matomo 5 to Matomo 4 in your Matomo development environment :

  • check out the “4.x-dev” branch 
  • run “composer install” as usual

  When will the final Matomo 5 release be available ?

  We estimate the final stable Matomo 5.0.0 release will be released in approx. 2-3 months.

  What is new in Matomo 5 ?

  We don’t have a summary of the changes available just yet but you can see all closed issues within this release here.

  Any questions or need help ?

  If you have any questions, or experience any problems during the migration, don’t hesitate to get in touch with us. We’ll be happy to help get your plugin compatible and the update published. If you find any undocumented breaking change or find any step during the migration process not clear, please let us know as well.

  Thank you for contributing a plugin to the Marketplace and making Matomo better. We really appreciate your work !
