[PATCH] Section Filter Read Abstraction
by Deti Fliegl 29 Jan '09

29 Jan '09

Hi, when using cDevice based classes that have no access to kernel based section filters it makes sense to have an abstract 'ReadFilter' function. The patch attached adds such a method to the cDevice class and changes cSectionHandler code to use the new method. Please add this patch to current 1.6/1.7 development versions. Deti

Delaying subtitles

Sadly the delay patch doesn't seem to work when used with vdr-1.6.0 + reelbox plugin. The subtitles seemed to come 6 seconds too early when watching a recording no matter what I set as delay value :( Regards, Josce

vdr plugin and kernel issues
by Halim Sahin 27 Jan '09

27 Jan '09

Hi List, I changed a dvdrecorder in my vdr and now the cdda plugin doesn't work any more. I found the following error: WARN: CDROMREADTOCHDR function not implemented. The kernel is a 2.6.23. Any idea what caused this? Do I need to ujpdate kernel, libcdio??? Which versions??? Thanks halim

consistent device removal
by Deti Fliegl 26 Jan '09

26 Jan '09

Hi, sometimes it is very useful to create and destroy cDevice based classes at runtime. Currently it is only possible to create such classes at any time but destroying causes inconsistency in the 'devices' array which leads to segmentation faults in various places. The patch attached keeps the 'device' array consistent on destruction of any cDevice based class. Please add this patch to current 1.6/1.7 development versions. The next thing to do is removing the MAXDEVICES constraint which should make it possible to add any number of cDevice based instances. Just in case you are interested why I need this feature: I am working on a native VDR plugin for the NetCeiver hardware. With this box it is possible to have up to 6 DVB-S2 devices (or DVB-S/C/T) per NetCeiver. You can attach up to 5 NetCeivers to a gigabit network which makes 30 DVB devices available. Therefore it should be possible to create and destroy DVB devices at runtime. Deti

[PATCH] ATSC for VDR 1.7.4

Delaying subtitles
by Josce 26 Jan '09

26 Jan '09

My problem is that vdr 1.6.0 with the reelbox plugin displays the subtitles 6 seconds too early. Does anyone know if there is a simple way to add a 6 seconds delay to the subtitles? I tried to look at the old subtitle plugin and how it was done there but couldn't see how to apply that to the subtitle handling that vdr does. Regards, Josce

[PATCH] Working PlayTsXXX to PlayXXX wrapper
by Udo Richter 26 Jan '09

26 Jan '09

Hi list, Attached is a new version of cDevice::PlayTsVideo and cDevice::PlayTsAudio that properly handles partially accepted buffers of the PlayVideo and PlayAudio functions. The original functions would discard any partially written data. These two functions are only used by devices that do not implement their own PlayTsXXX functions. The FF DVB devices don't use them any more, since TS is passed to (patched) DVB drivers. Other devices will soon play TS directly too. However, it might still be useful for patches that restore support for older drivers. ;) Cheers, Udo

[ANNOUNCE] Cuttime-patch for VDR-1.7.3
by Udo Richter 25 Jan '09

25 Jan '09

Hi list, The Cuttime-patch modifies the recording time of edited recordings to match the time of the first cut mark of the original recording. So if you start a recording 5 minutes earlier, and then later cut off the first 5 minutes, the resulting recording will have the proper start time again. Also, if you cut the recording into several parts, each part will co-exist with the other parts, since they will differ in starting time. The new version of the patch handles variable frame rates of VDR-1.7.3. Get it: http://www.udo-richter.de/vdr/patches.html#cuttime http://www.udo-richter.de/vdr/patches.en.html#cuttime Cheers, Udo PS: This should be the last one for today. ;)

[ANNOUNCE] Hard link cutter patch 0.2.1
by Udo Richter 25 Jan '09

25 Jan '09

Hi list, A first experimental version of the hard link cutter patch is available for VDR-1.7.4. The new version handles 1TB file sizes for TS recordings, properly calculates the switch-to-large-files for 65535 files, and also handles PES recordings properly with the old limits. For TS recordings however, the need for the file size switch is probably obsolete since the limit of 255 files is gone, so this feature might be dropped on later versions. Quick info: The hard link cutter patch changes the recording editing algorithms of VDR to use file system hard links to 'copy' recording files whenever possible to speed up editing recordings noticeably. For a complete list of changes, see web page. Don't miss the README-HLCUTTER included in the patch. http://www.udo-richter.de/vdr/patches.html#hlcutter http://www.udo-richter.de/vdr/patches.en.html#hlcutter Cheers, Udo

S2API wrapper patch 0.5 for VDR-1.7.4
by Udo Richter 25 Jan '09

25 Jan '09

Hi list, The new S2API-Wrapper patch for VDR-1.7.4 is ready. Beside adding support for the final 2G-flag, the patch also reverts the change that sends TS data directly to the device, since TS playback support is even newer than S2API support. Since TS to PES conversion by VDR-1.7.4 is also broken, its a good idea to also apply the PlayTS [1] patch. [1] http://www.linuxtv.org/pipermail/vdr/2009-January/019398.html Behavior can be configured in Make.config again: DEFINES += -DDVB_S2API_RUNTIME=1 enables the runtime detection (default) (NOT YET WORKING!) DEFINES += -DDVB_S2API_RUNTIME=0 disables the runtime detection DEFINES += -DDVB_S2API_WRAPPER=1 enables the API wrapper (default on old DVB headers and if runtime detection is enabled) DEFINES += -DDVB_S2API_WRAPPER=0 disables wrapper and runtime detection. Can be used to compile S2API without proper DVB headers. (default on new DVB headers and runtime detection disabled) Auto-detection will be back as soon as I know of a working mechanism to detect the presence of S2API drivers. Get it: http://www.udo-richter.de/vdr/patches.en.html#dvb-api-wrapper http://www.udo-richter.de/vdr/patches.html#dvb-api-wrapper Cheers, Udo
