Hi again, as mentioned last time when talking about the user interface for discourses, I was looking into the implementation of video streaming this time. For this task I wasn’t really able to workaround using RTP or something comparable. So I tried looking into it again with success. The problem I had with it previously was actually related to me overlooking the structure GstRTPBuffer in the documentation of GStreamer . With that I was able to calculate the actual durations of each buffer. I could simplify the code handling video and audio streams into one with only some variables like datarate which differ. But overall it worked for RTP via both rtpL16pay and rtph264pay nodes. So I could transfer H.264 encoded video via GStreamer now without major issues. However one thing I needed to solve was getting encoding done on many different platforms and form factors. Because not every SoC or device offers hardware encoding and decoding which is preferable though reducing power cost ...

Hello again, this month we finally got the release of GNUnet 0.21.0 and in addition we released a new release of libgnunetchat and both messenger front-ends . I tried to make sure the flatpak and snap packages work. However there were some difficulties. For example the flatpak runtime, the application uses, did not contain libportal for some reason. I needed to include that. The release of libgnunetchat caused a build issue because it required a dependency from the new meson build of GNUnet . The usage of Pipewire caused an immediate crash because of missing permissions. At the same time I worked on the flatpak manifest to make it update its dependencies automatically in the future via the external data checker that Flathub provides. public relation picture of the messenger application In the end the flatpak seems to work now. Only camera access is still not fully cooked yet. On my Librem 5 it gives a format error and fails to show an image. If no camera is connected at ...

Hey everyone, welcome to my second (maybe this will become yearly now) overview of what projects I contributed to over the last year. You might remember that I already had enough projects for a filled up schedule but I can ensure you, I found something to derail my focus even more. But let’s call it another little gift to unwrap instead. The graphical Messenger application only got a few fixes, mostly to patch package configurations. I also changed the build system from GNU Autotools to Meson . Hopefully that’s the last time I change the build system. The service in GNUnet got some more contributions from me lately. Partially because I got financial support from NLnet again which I’m thankfully for. Also because I want to bring my studies to an end and it’s a great topic for research. But honestly I want this project to become a practical option for messaging. So you can expect more contributions on this project in the next months as well as my monthly blog posts about its progres...
