[Patch] Make RGYB buttons customizeable
by Oliver Schinagl 07 Apr '11

07 Apr '11

Hey all, Ever had the trouble that your remote's color navigation key weren't the same as VDR's? Well I wrote this patch the past 4 hours which lets you configure them. By doing so, the order of the buttons in the menu changes depending on whatever you tell it to. So finally that remote can match whatever is displayed on screen. This only works for the classic and st-tng skins, as those are supplied with VDR. The Skin needs to support this feature. If there is no skin support, the setting … [View More]

[ANNOUNCE] VDR developer version 1.7.17
by Klaus Schmidinger 03 Apr '11

03 Apr '11

VDR developer version 1.7.17 is now available at ftp://ftp.tvdr.de/vdr/Developer/vdr-1.7.17.tar.bz2 A 'diff' against the previous version is available at ftp://ftp.tvdr.de/vdr/Developer/vdr-1.7.16-1.7.17.diff WARNING: ======== This is a *developer* version. Even though *I* use it in my productive environment. I strongly recommend that you only use it under controlled conditions and for testing and debugging. This version introduces support for TrueColor OSD. Note, though, … [View More]that output plugins need to be enhanced in order to support actual TrueColor display (if the device they control can handle TrueColor). Also, skins that want to make use of TrueColor may need to be adapted to the new interface using cPixmap. The changes since version 1.7.16: - Updated the Estonian OSD texts (thanks to Arthur Konovalov). - Fixed following symbolic links in RemoveFileOrDir() (cont'd) (thanks to Steffen Barszus). - Changed the description of cDevice::GetSTC() to make it mandatory for devices that can replay. - Removed the check for positive STC values from cDvbSubtitleConverter::Action(). - Added cString::operator=(const char *String) (suggested by Antti Seppälä). - Some spelling fixes (thanks to Ville Skyttä). - Passing package name and version to xgettext (thanks to Ville Skyttä). - Made 'dist' target dependent on up to date *.po (thanks to Ville Skyttä). - Added Language and fixed Language-Team header of *.po (thanks to Ville Skyttä). - Updated the Lithuanian OSD texts (thanks to Valdemaras Pipiras). - Fixed detecting frames on channels that broadcast with 50 or 60 fps. This avoids artifacts during fast forward/rewind when replaying recordings from such channels. To fix the index of existing recordings from such channels, just delete the 'index' file of the recording and VDR will generate a new one the next time you play it. You should also change the line "F 25" to "F 50" in the 'info' file of that recording. - Added support for "registration descriptor" to 'libsi' and using it in pat.c (thanks to Rolf Ahrenberg). - Fixed unjustified log entries about changed channel pids (reported by Derek Kelly). - Added an include of VDR's 'Make.global' to libsi's Makefile (thanks to Rolf Ahrenberg). - Removed displaying the "contents" information from the "Classic VDR" and "ST:TNG Panels" skins, because it is often wrong and nothing but irritating. - Added typecasts to avoid gcc 4.5 warnings in switch statements on eKeys variables where additional 'k_...' flags are used. - Fixed inclusion of <stdarg.h> (thanks to Henning Heinold). - Changed "frame duration" to "frame rate" in vdr.5 (reported by Tobias Grimm). - Removing a cRemote from the Remotes list in case its initialization failed (thanks to Dominik Strasser). - Added LDFLAGS to the linker calls in the Makefiles (thanks to Joerg Bornkessel and Paul Menzel). - Now updating the 'frames per second' data in the list of recordings when a new recording is started that has a frame rate other than the default. - The include path to the freetype2 header files is now retrieved via a call to 'pkg-config --cflags freetype2' (suggested by Andreas Oberritter). - The OSD now has full TrueColor support. There can be several "pixmaps" that can be overlayed with alpha blending. All existing skins should work out of the box with the TrueColor OSD - the only exception being cOsd::GetBitmap(). Since the TrueColor OSD doesn't use bitmaps, this function will return a dummy bitmap, which may not be what the plugin expects. As long as this bitmap is only used for setting the palette, there is no problem. However, any other operations on this bitmap will have no effect. See the description of the cPixmap functions in osd.h for details about the new functionalities. The "ST:TNG Panels" skin has been enhanced to automatically use the TrueColor OSD if available. The "osddemo" plugin has been extended to show some of the possibilities of the TrueColor OSD if it is run on a system that actually provides TrueColor support. Thanks to Reinhard Nissl for some valuable input, help with debugging, and an implementation of the AlphaBlend() function. - Updated the Slovakian language texts (thanks to Milan Hrala). - Added Serbian language texts (thanks to Milan Cvijanovic). - Fixed reallocating memory in the "pictures" plugin (reported by Paul Menzel, with input from Oliver Endriss). - Fixed reallocating memory in cTsToPes::PutTs() (suggested by Oliver Endriss). - Now checking the result of all realloc() calls. - Fixed setting up the 'Recordings' menu in case there are several recordings with exactly the same name (reported by Marcus Hilbrich). - Setting the audio type of language descriptors to 0x00 in the PAT/PMT generator (thanks to Anssi Hannula). - Changed the compiler optimization flag to -O3, which gives quite a performance boost in the AlphaBlend() function. - While replaying, the editing marks are now updated every 10 seconds (based on a patch from Manuel Reimer). - Now reducing the thread and I/O priority cCuttingThread::Action() to make the foreground process more responsive (suggested by Frank Neumann). - Removed checking for minimum line length of 21 characters in the LIRC receiver code (reported by Gerald Dachs). - Updated the Romanian OSD texts (thanks to Lucian Muresan). - Now storing the original display size when handling DVB subtitles (thanks to Reinhard Nissl). - The original display size of subtitles is now used to scale them properly when displaying them on an HD OSD. Have fun! Klaus [View Less]

vdr <-> vdr-xine <-> xine-lib and vdpau and HD recordings
by Joerg Riechardt 02 Apr '11

Hi, I have a problem with skipping during a replay of a HD recording. Running xine --verbose=2 I see after pressing the yellow button (skip +60 sec) lots of video_out: throwing away image with pts xxxxxxx because it's too old (diff : yyyyy) messages. This is for a few seconds or forever, depending on system load, and causes 100% Cpu, and spoils recordings on my slow system. On faster systems you will hardly notice this. If I patch cDvbPlayer::SkipSeconds with - readIndex = Index - 1; /… [View More]

[ANNOUNCE] dynamite plugin
by L. Hanisch 29 Mar '11

29 Mar '11

Hi, Some friends asked me to modify vdr/write a plugin, because their boxes boot so fast that most of the hardware is not initialized by the time vdr can start. They had to delay it or had to restart vdr when they think the hardware is ready. But since some pci-cards are 'fast enough' they would like to attach the 'slow' cards later while using the 'fast' cards for watching, recording etc. as soon as possible. So 'dynamite' was born (just some kind of wordplay with 'dynamic' and it sounds … [View More]more 'bombastic' and effective in advertising than 'dyndev' or whatever). :-) It's clear that this can't be done without patching the device handling inside vdr, so attached is my patch against vdr 1.7.17. It is designed in such a way that the original behaviour of vdr is not changed if the dynamite plugin is not loaded. I know that it is pretty invasive but it is as small as I could to do it. My knowledge of the inner relations of the various classes is certainly limited but I spent hours and hours on reading the source. And it is tested by a brave crew of volunteers. Nonetheless I would like to hear some remarks from the vdr-experts out there. In the following lines I will try to explain what this patch-plugin-combination is able to do and how it's done. It's a bit lengthy but it's important to me and I know it wouldn't get integrated at all if I don't give a wider overview about the concepts and ideas behind this. Features: - attach/detach devices While vdr is running you can dynamically attach/detach (unused) receiving devices to/from it. This could be a DVB-USB-stick or a very slow initialising piece of hardware (firmware load etc.). New devices are detected via udev, detaching should be made manually. If a frontend is in use udev is not sending a corresponding signal, there are just some messages from the usb subsystem, for example. The mapping to the right frontend and detaching it automatically is not trivial (in other words: it's on the TODO list). Also OSD integration is completely missing but will be added in the future. For attaching/detaching there are SVDRP commands (and Service calls for other plugins): PLUG dynamite ATTD /dev/dvb/adapter0/frontend0 PLUG dynamite DETD /dev/dvb/adapter0/frontend0 For a complete list of commands please read the README[1]. - set device on idle You can set a device to 'idle' mode. It will be ignored by the EIT scanner and closes all its handles. This is handy if you have enough tuners and want so save some power or preserve some frontends from being 'always on'. This is also a 'manual' feature, some kind of automatism is planned (some kind of timeout or similar). Of course it will be 'reanimated' automatically if a recording is starting or someone wants to look live-tv. - GetTSPacket timeout It is possible to set a 'GetTSPacket' timeout on the devices. If a device delivers no data for some time it can be automatically detached. This is intended for devices which has known unstable drivers. After detaching such a device a script is started so the driver can be reloaded and the device can be attached again to the vdr (this could happen on its own if the created frontend is signaled by udev). It avoids restarts of vdr and interrupting recordings on other devices. How this all is achieved: The class cDevice is extended by two fields: parentDevice and subDevice. The dynamite plugin provides a class derived from cDevice which passes all calls to its methods to its subDevice if one is attached. Otherwise it returns the appropriate values so vdr does think it can't receive anything (like the dummydevice output-plugin which can play everything). On the other side there are some methods in cDevice which have to be "parentDevice-aware", since they are called from other derived devices or classes inside vdr. Since parentDevice (and subDevice) are always NULL if dynamite isn't loaded, it's easy to preserve the original behaviour. To get the cDynamicDevice between the vdr and the device-creating plugins dynamite is doing two things: - it registers a cDvbDeviceProbe-object and moves it to the front of the list - the patch adds a second list 'cDynamicDeviceProbe' for 'dynamite-aware' plugins (like pvrinput as an example) On startup when vdr iterates through the dvb-devices dynamite captures all devices and adds a cDynamicDevice for every one to the global vdr-device-array. It asks all other cDvbDeviceProbes if they would like to create a device and attaches this as a subDevice. If no cDvbDeviceProbe is left it creates a core cDvbDevice on its own. After this it creates enough cDynamicDevice objects to flood the vdr-device-array. This ensures that vdr and other plugins always communicate with the devices through dynamite (like CAM, CI etc.) and so there is enough room for devices which will be attached later. If you use plugins which create (non-dvb-)devices which can't be handled by dynamite (like xine, iptv, streamdev etc.) they have to be loaded *before* dynamite. Actually it's best to load dynamite as the *last* plugin because then it can ensure that its cDvbDeviceProbe will be the first one. The dirtiest part of the patch is the modification of the constructor of cDevice. If the new 'parentDevice' parameter would be made non-optional, I don't have to use this ugly global placeholder... If it really gets integrated in vdr (I don't abandon hope on this), that would definitly gets cleaned up. But that would force changes on many plugins so I chose 'the dirty way'. Plugins which would like to use the functionallity of dynamite had to alter their device detection in their startup phase: - if dynamite is loaded just register a cDynamicDeviceProbe object and use the helper function QueueDynamicDeviceCommand from cDynamicDeviceProbe to queue the strings it needs to create the device objects. - if dynamite is not present create the devices like before - make sure you close all handles on destruction at the latest Look at pvrinput[3] as an example (cPvrDevice::Initialize at device.c:269 and at the end of that file) pvrinput uses strings like '/dev/video0' to identify the device it has to create. But these 'attach'-strings doesn't necessarily need to be real device paths. It's just a parameter to the Attach method of your cDynamicDeviceProbe object - so your fantasy limits the possibilities. :-) In the dynamite source you'll find a cDynamiteDeviceProbe which reacts on strings like 'dummydevice0' or 'dummydevice1'. It helped me while developing the SVDRP commands since I had only one DVB-T stick at my dev-vdr. You can activate it with a commandline argument. There are some caveats if you would like to use other patches together with dynamite if they also extend cDevice. Every new method has to be investigated if it should return its own value or the one of the parentDevice or subDevice (if it's present). And every new virtual method has to be added to cDynamicDevice at the dynamite plugin. If I had 'the power' I would integrate the functionality of cDynamicDevice completly into cDevice and leave the controlling at the plugin - but I'm realistic enough to know, that that would need a lot of convincing for my part... :-) As an example I added a reworked version of the lnb-sharing-patch to my repository[2]. Also I include some methods added by the patches yaVDR uses since this is my preferred distribution. So, anything left to say? It took me a while to write all this stuff down so for now I don't know if I had forgotten something important or not. I'm looking forward for comments. Of course I'm never responsible for broken or missed recordings (as no one is)! :-) Thanks for reading! Regards, Lars. -- P.S.: If you have a Sundtek stick and are interested in dynamite, please check out the sundtek-plugin[4]. It monitors devices via the libmedia/mediasrv and can even react on unplugging a device which is in use. -- [1] http://projects.vdr-developer.org/projects/plg-dynamite/repository/revision… [2] git://projects.vdr-developer.org/vdr-plugin-dynamite.git [3] http://projects.vdr-developer.org/projects/plg-pvrinput [4] https://github.com/flensrocker/vdr-plugin-sundtek [View Less]

remote frontend does not respond to keyboard after update
by Gero 27 Mar '11

27 Mar '11

Hello, I actually updated the vdr to recent developer version (from e-tobi) and now the remote frontend "vdr-sxfe" looks like sending different key codes to vdr. Changing chanels by cursor keys is the only that stil works. Before the update, vdr-sxfe sent XKeySym-codes to vdr, so it was easy to distinct between local and remote frontend by having diffent set of keycodes. I looked back the change history but could not find anything about those changes. May be I missed something. Does … [View More]

[ANNOUNCE] naludump patch 0.1
by Udo Richter 24 Mar '11

24 Mar '11

Hi list, I've uploaded the final patch version of the h.264 NALU fill removal for VDR 1.7.16. The patch deletes NALU fill data from h.264 streams while recording. The overall stream structure isn't modified, only complete TS packets of NALU fill data are dropped. On HD TV channels that use fixed video bandwidth, this can save 40-60% file size without loosing any data. The patch must be enabled at settings -> recordings, and can be activated/deactivated individually for each recording by … [View More]

[PATCH] VDR 1.7.17: fix frame detection
by Klaus Schmidinger 20 Mar '11

20 Mar '11

The attached patch reactivates some of the frame detecting code that was already in VDR 1.7.16, and adds a method of determining whether the current video stream consists of separate "fields" instead of complete frames. If this is the case, it puts two subsequent fields together to one frame in the index file. I know that the way this is detected (by counting the number of "frames" between two I-frames) is "guesswork", but until I see a case where this fails I'd say it still beats having a … [View More]
