DVB-T frontend time-out
by Dominique Dumont 17 May '07

17 May '07

Hello I'm trying to set up a WinTv Nova-T usb box with vdr (along with my regular NOVA-CI-S PCI card). This set up is working fine with Kaffeine, but vdr is unable to tune to a TNT channel. My channel.conf contains the following channels (got with scan -c while kaffeine was running): France 2:4294967:D12M64B8T8G32Y0:T:27500:120:130:0:0:257:0:0:0 France 4:4294967:D12M64B8T8G32Y0:T:27500:420:430:0:0:259:0:0:0 France 5:4294967:D12M64B8T8G32Y0:T:27500:320:330:0:0:260:0:0:0 ARTE:4294967:D12M64B8T8G32Y0:T:27500:520:530,531:0:0:261:0:0:0 LCP:4294967:D12M64B8T8G32Y0:T:27500:620:630:0:0:262:0:0:0 Anytime I try to tune to a DVB-T channel I get: vdr: [15337] frontend 0 timed out while tuning to channel 47, tp 4294 If I stop vdr, start kaffeine, I can receive the dvb-t channels correctly (no need to unplug/plug the dvb usb device as mentioned elsewhere) I'm using vdr 1.4.5-2.ds with xine plugin. Can anyone help me on this topic ? Thanks

softdevice crash
by aironet＠tigercomp.ro 16 May '07

16 May '07

Hi there, My config: - Asus M2NPV-VM (Geforce6150), Hauppauge nexus-s. - suse 10.0, kde, vdr-1.4.4. I recently purchased a 32" LCD-TV, and I would like to set up vdr-softdevice, to connect vdrbox via D-SUB or DVI to the TV set. I compiled ffmpeg-0.4.9-cvs and vdr-softdevice-0.4.0 without any errors. Probing vdr with softdevice: tigervdr:/opt/tigervdr/vdr-1.4.4 # ./vdr -c /vdrconf -P 'softdevice -vo xv:' [softdevice] processing args [softdevice] argv [0] = softdevice [softdevice] argv [1] = -vo vo_argv: xv: [softdevice] initializing Plugin [softdevice] Initializing Video Out [softdevice] ffmpeg build(3344640) [XvVideoOut]: Xinerama Screen 0: 0,0 1360x768 [XvVideoOut]: Xinerama Screen 1: 1360,0 720x480 [XvVideoOut]: osd_image shmid = 2949127 [XvVideoOut]: got osd_image: width 2080 height 768, bytes per line 4160 [XvVideoOut]: max area size 2046 x 2046 [XvVideoOut]: using area size 736 x 576 [softdevice] Subplugin successfully opend [softdevice] Video Out seems to be OK [softdevice] Initializing Audio Out [softdevice] Audio out seems to be OK [softdevice] A/V devices initialized, now initializing MPEG2 Decoder Segmentation fault I tried different ffmpeg and softdevice versions, with same result.

BUG: race condition triggered in cReceiver due to incorrect use by femon
by Reinhard Nissl 16 May '07

16 May '07

Hi, I've just got a pure virtual function call in cDevice::Action() for receiver[i]->Receive(b, TS_SIZE); It has happened while closing femon's OSD: (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0xb7f2fc4e in __lll_mutex_lock_wait () from /lib/libpthread.so.0 #2 0xb7f2ba3c in _L_mutex_lock_88 () from /lib/libpthread.so.0 #3 0xb7f2b42d in pthread_mutex_lock () from /lib/libpthread.so.0 #4 0x08124281 in cMutex::Lock (this=0xb762c48) at thread.c:190 #5 0x080a7cdc in cThread::Lock (this=0xb762c38) at thread.h:91 #6 0x080a5548 in cDevice::Detach (this=0xb762c38, Receiver=0xb099ab0) at device.c:1298 #7 0x080effb9 in cReceiver::Detach (this=0xb099ab0) at receiver.c:60 #8 0x080f0090 in ~cReceiver (this=0xb099ab0) at receiver.c:43 #9 0xb799ac29 in cFemonReceiver::~cFemonReceiver () from /soft/vdr-1.4.6/lib/vdr/libvdr-femon.so.1.4.5 #10 0xb7998b05 in cFemonOsd::~cFemonOsd () from /soft/vdr-1.4.6/lib/vdr/libvdr-femon.so.1.4.5 #11 0x08131da7 in main (argc=20, argv=0xbf90e914) at vdr.c:885 #12 0xb7ce6f9c in __libc_start_main () from /lib/libc.so.6 #13 0x08091111 in _start () (gdb) cReceiver::~cReceiver() calls Detach(), but at that time, it is simply too late as the virtual method table entry for Receive() has already been restored to 0. I suggest to call Detach() from cFemonReceiver::~cFemonReceiver() to fix this issue. Furthermore I suggest to add some debug output to ~cReceiver() in the case where the receiver is still attached. I've been using femon for quite some time now and it was the first time, that VDR dumped a core regarding a pure virtual function call. Such a debug output would have triggered way more early.

Bug/SegFault in vdr-1.4.6
by Patrick Cernko 16 May '07

16 May '07

Hi List, I think I just found a bug/segfault in vdr's timer handling. Could someone please verify that: 1. start with empty timers list 2. schedule some timers (at least 2) 3. Go to the timers menu and "deactivate" all but the last. 4. deactivate the last timer -> CRASH Also happens when selecting all timers in vdradmin's timer menu and pressing "inactivate". To fix the resulting Crash-loop, remove the timers.conf file. Is this happening only to me or can someone reproduce it? So long, -- Patrick Cernko | mailto:errror@errror.org | http://www.errror.org "Wo wir schon bei den Drogen sind kommen wir auch gleich zum Hip-Hip." (Jimi Blue Ochsenknecht, Echo-Verleihung 2007)

Feature requests
by Pasi Juppo 16 May '07

16 May '07

Hi, There are couple of annoying problems in vdr (v1.4.4 at least but most likely also in never ones): 1) If there is data stream problems in a channel VDR initiates emergency exit. This can be a temporary situation and gets fixed in few seconds to minutes. To solve this: change to other channel and infor user via OSD ("Channel not available" or something similar) 2) If there is no data comming from the channel (e.g. new decrypting card that needs to be updated first before it is ready to be used or for some reason the key is not available) VDR initiates emergency exit. Unnecessary action and user can do shutdown action if this is really a problem. To solve this: do not initiate emergency exit but show message in OSD ("Channel not available"). Basically every unnecessary exit should be avoided because it does not provide any advantage to the user - just the opposite. Problems should be informed to the user and let user decide what to do in case of long lasting problem such as missing data stream. Minor feature that would be nice: 3) If there is a problem like crash with VDR and a timed recording did not get recorded VDR simply deletes the timer without notifying user. Of course the timer as such is useless but it would be nice to see that this and this recording was not done at all, was not started in time or was not recorded fully. This way the program can be re-recorded if/when it is broadcasted again. And if this information can be asked from VDR then epgsearch or other plugins can try to find missed programs again automatically. Br, Pasi

Best settings..
by JJussi 14 May '07

14 May '07

Hi! I have very simple and still hard question.. At vdr pluging setup - xineliboutput - Video. Post processing (ffmpeg) and Deinterlaceing. What ARE best values (to select) when you have HD LCD (via DVI) as TV and enough CPU power (Intel Core 2 Duo) to use. I think that I'm not only one who thinks that there is too many choices.. ;-) -- JJussi

[PATCH] dynamically sized ringbuffers v2
by Artur Skawina 12 May '07

12 May '07

Auto sized ringbuffers, changes since v1: - increased maximum sizes for a few rb users. Most of the time just a small part will be used, but there will be more room for times when more is required. - a little smarter cRingBufferLinear::Read(), handles the TS buffer better. - faster buffer growth. Also makes it less likely that there won't be an opportunity to resize before an overflow. - a potentially sleeping cRecorder:Receive(). Mostly to find out how much more buffer/time would have been needed, ie debugging. - more verbose logging. It still wouldn't surprise me if this version caused a few overflows, but hopefully these will be very rare. artur diff --git a/dvbdevice.c b/dvbdevice.c index 955483e..20dcf29 100644 --- a/dvbdevice.c +++ b/dvbdevice.c @@ -1184,7 +1184,7 @@ bool cDvbDevice::OpenDvr(void) CloseDvr(); fd_dvr = DvbOpen(DEV_DVB_DVR, CardIndex(), O_RDONLY | O_NONBLOCK, true); if (fd_dvr >= 0) - tsBuffer = new cTSBuffer(fd_dvr, MEGABYTE(2), CardIndex() + 1); + tsBuffer = new cTSBuffer(fd_dvr, MEGABYTE(8), CardIndex() + 1); return fd_dvr >= 0; } diff --git a/recorder.c b/recorder.c index 8bb1621..3c0e002 100644 --- a/recorder.c +++ b/recorder.c @@ -157,8 +157,20 @@ void cRecorder::Receive(uchar *Data, int Length) { if (Running()) { int p = ringBuffer->Put(Data, Length); - if (p != Length && Running()) + if (p != Length && Running()) { + for (int ms=20; ms<1000; ms+=ms) { + cCondWait::SleepMs(ms); + if (!Running()) + return; + int r = ringBuffer->Put(Data+p, Length-p); + p += r; + if (r) + dsyslog("saved extra %d bytes in recorder ring buffer after %d ms delay", r, ms); + if (p == Length || !Running()) + return; + } ringBuffer->ReportOverflow(Length - p); + } } } diff --git a/remux.c b/remux.c index da805b7..bd29b2f 100644 --- a/remux.c +++ b/remux.c @@ -1851,7 +1851,7 @@ void cTS2PES::ts_to_pes(const uint8_t *Buf) // don't need count (=188) // --- cRemux ---------------------------------------------------------------- -#define RESULTBUFFERSIZE KILOBYTE(256) +#define RESULTBUFFERSIZE MEGABYTE(2) cRemux::cRemux(int VPid, const int *APids, const int *DPids, const int *SPids, bool ExitOnFailure) { diff --git a/ringbuffer.c b/ringbuffer.c index 0633bd3..39cc02e 100644 --- a/ringbuffer.c +++ b/ringbuffer.c @@ -151,13 +151,30 @@ void cRingBufferLinear::PrintDebugRBL(void) } #endif +// cRingBufferLinear are dynamically sized, or at least we can pretend they are ;) +// We treat 'Size' as the maximum size, but start with a small buffer, which can +// grow later as it fills up.
