• mp4 video on Android

  9 février 2016, par matthewbaskey

  I wanted to convert some old Flash videos to 1 video format so the content will show on a mobile phone. I got some mp4 and it doesn’t work on Android, specifically Chrome 32 running on Android 4.3.

  Click this link to a fiddle

  It is loading the mp4 file on Chrome 32 on Android 4.3, but I thought there is no support for H.256

  Then I went to a this site http://techslides.com/sample-webm-ogg-and-mp4-video-files-for-html5/

  and the mp4 video there works on Android/Chrome.

  I used VLC to check the codecs and they look the same

  H264 - MPEG-4 AVC (part 10) (avc1)
  
  Resolution: is different (working one is 560x320
  
  Resolution: mp4 not working is 640x480
  
  Framerate: working is 30, not working is 12
  
  Decoded format: Planar4:2:0 YUV

  I then searched the codec then with ffmpeg and I see that
  there is a property called
  compatible_brands : mp42icomavc1

  which is different than the non-working mp4 which has this property set to
  compatible : mp42mp41

  The file sizes are quite different as well. Could this be an issue.

  When I load http://html5test.com the Chrome on Android browser says MPEG-4 is not supported by H.264 is. it doesn’t say anything about the container.

  ok here is some source code, I thought chrome on android doesn’t support mp4 files, but when I load the following on Chrome 32 running on Sony Xperia Tablet running Android 4.3. I had an mp4 file that I converted to webm, but chrome still could not run it. It is 8 MB so perhaps the size is an issue....this mp4 has a different size and frameframe. Other than that I only see compatible version different as mentioned above.

• MEDIA_ERR_SRC_NOT_SUPPORTED while playing mp4 only in Safari

  18 novembre 2020, par sabotage

  I'm trying to play an mp4 file which plays fine in Chrome/Firefox but results in error (MEDIA_ERR_SRC_NOT_SUPPORTED) in Desktop/Mobile Safari.

  


  I've attached response of the request from charles.

  


  Ive created the video file using ffmpeg : ffmpeg -loop 1 -i audioOnlyModeMsg.jpg -c:v libx264 -t 3 -pix_fmt yuv420p -vf scale=320:240 out.mp4

  


  the jpg is just a black picture with a message in the center. Overall it's a still 3 second video.

  


  I tried other answers, I changed response status to 206, it didn't work.

  


  I checked this link (https://developer.apple.com/library/archive/documentation/AppleApplications/Reference/SafariWebContent/CreatingVideoforSafarioniPhone/CreatingVideoforSafarioniPhone.html#//apple_ref/doc/uid/TP40006514-SW6) where there is a test for checking if byte range is supported by my server, it worked too.

  


  Please help me out, what is going on here ?

  


  you can run this here : https://jsfiddle.net/dcm97h41/1/
please try on chrome for expected result and safari for error

• To all Matomo plugin developers : Matomo 4 is coming, make your plugin compatible now

  6 août 2020, par Matomo Core Team — Development

  We’re planning to release the first beta of Matomo 4 in a few weeks. For making it easy for Matomo users to be able to upgrade to this beta, it would be great if as many plugins on the Marketplace as possible would be already updated and compatible with Matomo 4. 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 4 helps ensure that people will be able to find and keep using your plugin. If your plugin is not compatible with Matomo 4, your plugin will be automatically deactivated. We’ll be happy to help you achieve compatibility should there be any issue.

  How do I upgrade my Matomo to Matomo 4 ?

  If you have installed your Matomo development environment through git you can simply checkout the Matomo 4 branch “4.x-dev” by executing these commands :

  • git checkout 4.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 4 ?

  • We recommend you create a new branch for your plugin that supports Matomo 4. For example a branch named “4.x-dev“. This way you will be able to make changes to your plugin for Matomo 3 and Matomo 4 and release separate versions.
  • Check out our migration guide from Matomo 3 to Matomo 4 and the list of all breaking changes.
  • Release a new version of your plugin in GitHub as usual.

  While there were many breaking changes in Matomo 4, most of our Platform APIs remain unchanged, and almost all changes are for rarely used APIs. Often to make your plugin compatible it 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 4.

  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 I downgrade to Matomo 3 or switch between Matomo 3 and Matomo 4 ?

  To downgrade from Matomo 4 to Matomo 3 :

  • check out the “3.x-dev” branch 
  • run a composer install as usual. 
  • run the SQL statements from this downgrade guide to restore the previous MySQL schema.

  When will the final Matomo 4 release be available ?

  We estimate the final stable Matomo 4.0.0 release will be released in approx. 3 months.

  What’s new in Matomo 4 ?

  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 !
