Instability with recordings on VDR-1.7.4 when recording to a NTFS partition
by Hawes, Mark 20 Mar '09

20 Mar '09

Hi, Since upgrading to VDR-1.7.4 I have experienced some instability when recording to an NTFS partition. The recording itself seems to proceed OK, but the recorded programs will generally only play for a few seconds before freezing. Pausing live video and then resuming play will also trigger the problem. Subsequently rewinding a recording that has been so paused will only rewind to the pause point, not the beginning of the recording. All works well when using vdr-1.7.2 to record on … [View More]

Hi My issues. May be I not right, but.... 1. Have: use section filtering - "yes", disable filters - 0. Have a iptv channel in channel.conf, but absent and not streaming now. Switch channels: work channnel -> absent channel -> work channel. And vdr hangs, almost always.... If set use section filtering - "no", all works. If set use section filtering - "yes", disable filters - 1, PAT, all works too. 2. pat.c use Channels.GetByServiceID. Channels.GetByServiceID use ISTRANSPONDER(). #… [View More]

PMT in multiple TS packet bug
by Alexw 16 Mar '09

16 Mar '09

Hi Klaus, I have noticed a PMT parsing issue with VDR version 1.7.x. The bug is still present in version 1.7.3 but the behaviour is worst because it segfaults. First I found out that 2 lines where added in the ParsePmt method. Data += Data[0] + 1; // this is the first packet Length -= Data[0] + 1; At the moment I don't know exactly what is the meaning of this 2 operations. The second line can result in a negative Length which is the reason of the segfault. Could you kindly … [View More]

power consumption, powertop and wakups per second with a af9015 device
by Heinrich Langos 16 Mar '09

16 Mar '09

Hi, I just installed vdr 1.6.0 on Debian stable (Lenny). I run it on an old notebook (Dell 1300, 1.5 GHz Celeron M). Up until now the system was a network storage for some windows clients and a music player for my living room. Now I plan to use vdr as a remote controled VCR. To keep it quiet I checked with powertop and got rid of most software that does short idle loops. Now the system shows less than 10 wakeups per second from sleep. That is with dvb_usb_af9015 loaded but with "remote=… [View More]0" module parameter to disable the remote control input that aparently is done by polling. (With "remote=2" it goes up by about 50 wakeups per second. OK, AFAIK USB input devices need to be polled. No way around it. But does it have to be at 20ms intervals?) Anyway, the real fun comes with starting vdr. With vdr runing I get a whopping 2700 wakeups per second! And thats doing nothing at all. No recording, no playback no streaming. Nada! The result is a 30% CPU load (admittetly at a low P-state) and a constantly runing CPU fan. I don't know what vdr does, but it causes the device to jump through a lot of (idle) loops. At least thats what I'd read from the output of powertop. Does anybody have an idea as to what it causing this? Any comparative data for other devices? I also own a "Fujitsu-Siemens DVB-T Mobile TV Tuner" and I'll take a look and try to find out if that device will generate less system load.

Thank you for your responses. I would be happy for any help offered and would gladly share any results I come up with. If anyone wants my diffs for building xinelib/vdr-fbe on PCH, please mail me. For me, the overall goal is: - Get the functionality of a full VDR frontend on PCH The current tech. idea is; - Use mono to display audio/video - Use custom directfb app to display xineliboutput VDR OSD and get lirc input The initial tasklist as I see it: - Test mono with xineliboutput http … [View More]

image 0.3.0 with high resolution output
by Alex Betis 14 Mar '09

14 Mar '09

Hi all, In case you have a high resolution output device (LCD/Plasma) you probably noticed that image plugin show low quality results even when the original image is a very high quality/resolution. To fix it, replace the following lines in liboutput/encode.c file from: m_nWidth = 720; m_nHeight = m_bUsePAL ? 576 : 480; to m_nWidth = 1920; m_nHeight = 1080; Or other output resolution if you don't have a full HD screen. Developers of image plugin, it would be great to … [View More]
