Coder's Log

Ever since I blogged about me looking for opportunities outside Nokia , I was contacted by quite some companies. Some of them ended-up giving me nice offers but in the end the offer that stood out amongst all was from Red Hat . So last evening, I accepted their offer to join the awesome Spice team. The reasons I chose Red Hat over others were: Red Hat being undoubtedly the leader in Open Source technologies for more than a decade has always been on my 'awesome places to work at some day' list. The Spice project that I'm being hired to work on is simply awesome. They offer good working conditions. I'll be staying in Finland and most likely working from home (unless I'm asked to work at the Espoo office). I will be officially joining Red Hat on May 2 and my last day at Nokia will be on April 21. Before you ask, nothing disastrous is going to happen to GUPnP and Rygel . Of course I won't be spending as many hours on these projects as now but keeping in m

Zachary Goldberg reports : As I've been mentioning lately I have been working on using PyGObject + GObject Introspection (recently forked, now called PyGI + PyGObject + Gobject Introspection) and have some exciting news! I have been working on fleshing out a whole bunch of unit tests which exercise the entire GUPnP API. I hate a major roadblock in that PyGI did not support native callbacks! So, after a week or two detour I have implemented PyGI callbacks (which now work rather nicely, but need a bunch of stylistic cleanups and error checking before its pushed back upstream.. priorities!) as well as some working GUPnP demos. My best demo so far is about 25 lines of python which: 1) Gets all devices on one network interface 2) Scans for all the services each device provides 3) If the device is GMediaRenderer and it provides an AVTransport Service (it does...) then it 3a) Stops whatever is currently playing 3b) Loads a new URI (hardcoded from my mediatomb server for now, h

Rygel 0.4 (Fascinating!) is out! As usual, the release announcement: Brief summary of changes since 0.3: - Rygel is no more just a MediaServer but rather a collection of DLNA (UPnP AV) services (devices in UPnP speak). - Port to new GUPnP APIs. The biggest advantage of that is that we now have dynamic network support, i-e Rygel can attach/detach to/from a network interface as it goes up/down. - Support for time-based seeking in transcoded streams. - Random tweaks to transcoding pipelines. - Provide a DBus service providing two functionalities: * Ability to tell Rygel to shutdown. Starting of Rygel is automatically handled by D-Bus since a .service file is provided by Rygel. * Ability to tell Rygel (MediaExport plugin actually) to (un)export URIs on the fly. - Implement enabling/disabling of UPnP in the preferences. - Configuration through command-line options. - Use a .ini configuration file rather than gconf. - Special default configuration for Maemo. - Don

GSSDP 0.7 released! Changes in this release: - Join the multicast group on the specified interface. - Put the message src timeout in the specified GMainContext. - "host-ip" property moved from GUPnPContext to parent GSSDPClient. - Use inet_aton instead of inet_addr and handle the error from it. - gssdp-device-sniffer ported to GtkBuilder. - Version-independent target match. This makes client forward and backward compatible with resources that implement different version of the specs than the client. - Version-independent M-SEARCH response. This has the same effect as above but only the other way around. - GSSDPClient now binds to interface rather than IP. - No need to find the default route. - Add "active" property to GSSDPClient. - Fix pkg-config paths. - Add basic .gitignore. - Other minor/internal changes. Bugs fixed: 1621 - new gssdp timeout not added to the specific maincontext 1570 - gupnp doesn't set the pkgconfig lib dir correctly in 64 bit env Dependenc

Changes since 0.12.7 - Don't crash if device descriptions don't contain a root element. - Fix pkg-config paths. - Avoid using asserts. - Use the closest match instead of using the icon that was last checked. - Expect xmlRecoverMemory to fail. - Reject action messages with zero content length. - Change version in action answer. Bug fixes in this release: - bug#1570: gupnp doesn't set the pkgconfig lib dir correctly in 64 bit env. - bug#1574: Avoid using asserts. - bug#1592: gupnp_device_info_get_icon_url() does not return the closest match. - bug#1604: Crash on action without any content.

I have been asked several times in the past if gupnp is portable enough. I always told them that I don't know for sure but the only problem i see is the low-level networking bits. Nobody really showed interest in actually trying it out on windows but then came Jens Georg. He managed to make gupnp stack and network-light working on windows within a weekend, despite the fact that some of his hours were wasted due to firewalls being enabled after a reboot and him forgetting about it. He has a small video of network-light running nicely on win32 on his blog .

Last night I tried to make a small app/script in javascript (gjs) and it actually worked. :) Here is the code: const GLib = imports.gi.GLib; const GUPnP = imports.gi.GUPnP; const Mainloop = imports.mainloop; // This doesn't start any threads GLib.thread_init (null); let context = new GUPnP.Context ({ main_context: null, host_ip: null, port: 0 }); let cp = new GUPnP.ControlPoint ({ client: context, target: "ssdp:all" }); function onDeviceProxyAvailable (cp, proxy) { log (proxy.get_friendly_name ()); } // Tell us when there is a new device available cp.connect ("device-proxy-available", onDeviceProxyAvailable); // Search and listen for UPnP resources on the network cp.set_active (true); Mainloop.run ("0");

GUPnP AV 0.4 released. New in this release: - Watch for empty DIDL-Lite nodes. - Escape the URIs before putting them into DIDL-Lite XML. - The '.' must be omitted from duration if fraction part is not included. - Be more lenient when parsing DIDL-Lite XML fragments. - Don't require the DLNA profile string. - Try to guess the DLNA Profile if not provided and put "*" in the whole 4th field of protocolInfo if our guess work fails. - Make sure 4th field of protocolInfo is completely in compliance with DLNA guidelines. This only implies one change in the API: enum dlna_play_speed is replaced by play_speeds, a GList of allowed play speeds as strings. - Use '1' and '0' to express boolean properties in DIDL-Lite XML. - Other minor fixes.

When GUPnP was first used at Maemo software, one of the first questions I was asked was: Can't GUPnP handle multiple network interfaces just like ClinkC (the now deprecated UPnP framework in Maemo)? The answer to that question was "yes but you have to take care of creating GUPnPContext objects for each network interface yourself" and that wasn't very convenient. This issue, accompanied by the fact that applications had to know when the interfaces go up and down to create and destroy the associated GUPnPContext object themselves, made the lives of application developers not so easy. Recently when this issue was raised on the mailing-list and bugzilla by two different people, I started to think about how to solve this issue. Keeping in view Ross ' advice I came-up with the following solution A GUPnPContextManager class that basically just have two signals: "context-available" and "context-unavailable", that it uses to create/destroy and report

Rygel 0.2 is out. Here is the release announcement: The major change after last release (as gupnp-media-server) is the introduction of a simple yet powerful plugin-based architecture/api: Everyone plugin: - is loaded into a separate MediaServer instance. - can implement any kind and number of resources (currently only services). - can export an icon file. - inherit it's ContentDirectory implementation from a base class that does most of the UPnP-related work. More improvements on this planned for next release. - use an intuitive API to easily export media from URIs and live GStreamer source elements over HTTP. Other changes: - Relicense under LGPL to allow proprietary plugins and ease of moving code from/to gupnp libraries. - DVB Daemon integration though a plugin. Now you can watch live channels from your PC on your PS3 for example. - Test plugin that exports one audio and video item, streaming contents from GStreamer's audiotestsrc and videotestsrc elements respect

Thanks to Ross and Richard Purdie, GUPnP moved to Git today. I already updated the jhbuild modulesets to reflect the new repos.
