Hi! I've adapted Thomas Schmidt's dd-record-option patch to VDR-1.7.4. Additionally French language texts have been added (thanks to Michaël Nival). Download from: http://toms-cafe.de/vdr/download/vdr-dd-record-option-1.6.0.diff http://toms-cafe.de/vdr/download/vdr-dd-record-option-1.7.4.diff This patch allows you to choose if to record and to replay Dolby Digital independently.

[PATCH] jumpplay patch 1.0 for VDR-1.6.0 and VDR-1.7.4
by Thomas Günther 31 Mar '09

31 Mar '09

Hi! Here is a new version of the jumpplay patch: http://toms-cafe.de/vdr/download/vdr-jumpplay-1.0-1.6.0.diff http://toms-cafe.de/vdr/download/vdr-jumpplay-1.0-1.7.4.diff This patch changes the replay behaviour for recordings that contain editing marks. It allows to immediately continue the replay after jumping forward to the next mark, and to automatically jump over the commercial break to the next "start" mark, if an "end" mark is reached. The features of this patch can be turned on or off in the replay setup. See README.jumpplay included in the patch for details, history and contributors. Changes since version 0.9: - Play&Jump: - set resume position to 0 if replay stops at the first mark - Added French language texts (thanks to Michaël Nival) Tom

In my understanding USB does not use > DMA and that's why it generates high load? DMA is only possible between memory and the USb host controller. The USB device is always polled for data. Even the so called interupt transfer mode is nothing but a high frequency polling mode... well USB sucks compared to firewise but than again, usb devices are cheap as chips because they can be stupid. I ran a couple of tests with a different DVB-T USB stick. The rather old "Fujitsu-Siemens DVB-T Mobile TV". That one turns out to need a lot less system resources. It also transfers the whole transport stream (several video and audio streams) over the USB and leaves demuxing to the host. So we are not comparing apples and oranges. Comparing those numbers seems to indicate that there is room for improvment for the af9015 driver. I'll try to get my hands on a couple more different usb receivers to try out some of the other drivers. What I also found rather scary was the 200 wakups per second that vdr did even when there is no dvb device to read from. So I removed all vdr plugins and started adding them one by one. epgsearch - no problem live - no problem streamdev-server - no problem ffnetdev - BINGO Which makes sense when considering that ffnetdev tries to implement a full featured card in software. I just didn't know they also try to implement an INPUT device! With the usb device enabled, I get various degrees of CPU load, depending on the plugins installed, but in general the number of wakeups per second is constant at about 200 per second. Even without any plugin and with noting to do. In other words: vdr is polling its input devices at 200 Hertz even when is is completely idle! I wonder if that is realy necessary... Some vdr guru willing to enlighten me? (I'm willing to dodge the stones thrown at the heretic :-) ) cheers -henrik PS: I am willing to take the whole driver thread off-list if somebody feels that this is not the proper list for it, but I think the way vdr behaves when it is idle is interesting to more people.

[FRC] Why are patches for framebuffer not needed anymore in release 0.1.0?
by Paul Menzel 29 Mar '09

29 Mar '09

Dear Thomas, you released version 0.1.0 [1]. Could you please explain to me, why the framebuffer patches (intelfb, radeonfb) are not needed anymore? Thanks a lot, Paul [1] http://lowbyte.de/vga-sync-fields/vga-sync-fields/

xinelibout --hud + xcompmgr = tearing
by Alex Betis 29 Mar '09

29 Mar '09

Hello all, I gave the nice xinelibout hud another try, but have to revert back since running composite manager creates tearing while watching movies. I've tries with xcompmgr with -n option. Does anybody know how to fix that? Or maybe there is another lightweight composite manager available? Without xcompmgr running there is no tearing at all. Thanks.

Where do you live and what kind of broadcast do you receive?
by Petri Helin 28 Mar '09

28 Mar '09

Hi, I have wondered for some time how broad has VDR spread and how is it really used. So, if people could post their location and the type of broadcast they are receiving, we could get some kind of understanding about the state of DVB (or ATSC) as it is now. Just a brief description, using myself as an example: Country: Finland Transmission: DVB-C Encoding: MPEG-2 for SD (tens of channels) and h.264 for HD (less than 10 channels) The main point is to get an idea of the standards used across the globe. I know that wiki etc give some idea, but you can never beat the first hand information. -Petri
