• Use HLS from Wifi device as input to stream over 4G

  26 février 2017, par pbdev

  I’m building an Android app that streams video from a Wifi device to a Wowza server. It should be quite simple but I can’t figure out how to use both Wifi and 4G at the same time. The device I’m using is a Samsung S5 with Android 6.0.1. To sum it up, this is the goal :

  1. Fetch the video stream from a GoPro device over Wifi.
  2. Send the video stream to a Wowza server over 4G.

  When connected to the GoPro’s Wifi network I can ping the GoPro and see the stream in a MediaPlayer. Since I’m connected to a Wifi device that doesn’t provide internet access, I can’t ping my Wowza server. Once I’ve disabled Wifi this is no problem, by using FFmpeg I can reach the Wowza server over 4G.

  This is the FFmpeg command I want to use to copy the stream to the Wowza server, where 10.5.5.9 is the IP-address of the GoPro :

  ffmpeg -i http://10.5.5.9:8080/live/amba.m3u8 -acodec aac -ar 44100 -ab 48k -vcodec copy -f flv rtmp://username:password@my-wowza-server.com:1935/my-app/my-stream

  If I enable Wifi and connect to the GoPro, 10.5.5.9 is reachable but my-wowza-server.com isn’t. The Samsung S5 provides a Smart network switch which makes the Wowza server reachable but the connection to the GoPro gets lost.

  Is there any way to bind 10.5.5.9 to the Wifi interface of the phone and bind my-wowza-server.com to the cellular interface ?

• FFmpeg : create data streams in MP4 container

  28 mars 2022, par Soeren

  Is there a way to make FFmpeg create data streams in MP4 or Quicktime (.mov) containers ? I have tried -attach ... (works fine for Matroska containers, but not MP4/MOV) or -codec bin_data, but to no avail.

  


  -attach ... technically creates streams with codec type "attachment", which are different from data streams. And while FFmpeg isn't smart enough to directly create data streams in containers where attachment streams aren't supported (ie. MP4), a two-step approach works :

  


  ffmpeg -i <some media="media" file="file"> -attach <some file="file"> -metadata:s:2 mimetype=<data mime="mime" type="type"> -map 0:v -map 0:a -codec copy attached.mkv&#xA;ffmpeg -i attached.mkv -codec copy attached.mp4&#xA;</data></some></some>

  


  The first command creates a Matroska file that contains a stream with codec_type=attachment. The second command then simply re-packages this into an MP4 container, turning the attachment stream into a data stream (codec_type=data). So the question is : could this be combined into a single step ?

  


• Projects from behind-the-scenes

  Kia ora from the marketing team !

  Marketing team ? That’s right ! You haven’t heard from us in the past, but we’ve been working in the background to create a better experience for you, our dedicated Matomo community.

  Kia ora ? Well, that just means “hello” in Maori, we’re based in New Zealand you see.

  The Matomo marketing team has some really exciting projects in the works we wanted to share with you, but first, there’s someone I want to introduce :

  Meet Joselyn from the Matomo Marketing team

  Meet Joselyn, one half of the Matomo marketing team and our Digital Marketing and Communications Specialist. Joselyn has come on board to help us communicate more frequently and effectively as we continue our mission to be the #1 free open source analytics platform in the world. Please take it away, Joselyn !

  “Hi everyone ! The team here at Matomo have been doing an incredible job passionately driving the cause for user privacy and data ownership and uniting that with a love for digital analytics. It’s exciting being a part of a team unafraid to push on with their hearts on their sleeves and their values at the forefront of everything they do. I hope to bring to light all the fantastic things happening in our world of web analytics as well as across the globe.

  

  Our online world is fascinating when we think about what we can achieve with analytics, but there’s room to improve. We see newer technologies, but old ways of working which don’t take into account a person’s safety online. So we hope to champion a new future which looks set to be much more meaningful. Ensuring you get the best experience, but also feel protected with the knowledge that we get it. Your data and privacy isn’t for sale.

  I also hear you guys, the community, have followed Matomo since the beginning, which is wonderful ! I hope you’ll be able to join us as we grow and learn. We’ve got so many thrilling things to share with you. The highs, the lows and everything in between. Cheers !”

  Thanks Joselyn ! On top of working to engage the community and new users, Joselyn will also be keeping the rest of the Matomo team on our toes getting the inside scoop on what’s happening within the Development and Support teams ; as well as giving you behind-the-scenes access to what’s going on here at Matomo. We have a big vision and with so many things happening right now, we want to get you involved as much as possible.

  It may sound a bit clichéd but I’m saying it anyway – without your help, Matomo wouldn’t be here today.

  Help us choose a logo

  So first of all, we want you to say thank you and second we’d be delighted if you could help choose our new logo ! As you may already know, we changed our name from Piwik to Matomo at the start of the year. Though it was fun using a cool font (Aileron Heavy btw) as a quick fix for our name change, it was a temporary solution. The Matomo team has been involved in the direction of creating a new logo, but now we’re stumped ! We have three different concepts to choose from so please help us out !

  A new website for Matomo.org !

  Other exciting marketing projects include a new website design (yay !) – to everyone gasping nervously…don’t worry, nothing in what we offer is changing. We are and always will be a freely accessible open source analytics platform, just wanted to quickly clear the air on that one !

  We also have some video projects in the works to make the Matomo experience better for everyone and there are even rumours a brand video that tells the Matomo story is on the way ;)

  What next ? With Joselyn on board and loads of exciting projects happening, it won’t be long until you hear from us again, so keep an eye out for our next update as we reveal the winning Matomo logo.
