Help identify packets in MPEG-TS stream
by Artem Makhutov 17 Dec '08

17 Dec '08

Hello, I would like to get my STB playing back video streams from streamdev-server. The stream is transmitted my streamdev using IP-Multicast and can be played back without any problems with VLC, but the STB has big problems with the stream. The stream itself is from the ASTRA HD+ demo channel. In the stream I can see a lot of clear-text messages like: "Wilde Abenteuer und jede Menge Spaß und Action mit dem Tasmanischen Teufel" or "Der geht brutal gegen die Rebellen in den Wäldern vor. Bei ihrer Ankunft trifft Ofelia auf einen mysteriösen Faun" I does not look like this messages belong to the stream (they do not look like subtiles or audio-track descriptions). Could this be some kind of EPG data, or what is this? When streaming this recording using VLC as streaming server the STB can playback the stream without any problems, as this messages are removed by VLC. I have captured a few seconds of the stream: http://www.makhutov.org/downloads/adb/hdtv.pcap http://www.makhutov.org/downloads/adb/hdtv.ts Can you help me identifying what this messages are? Thanks, Artem

cTS2PES::write_ipack infinite recursion
by Andreas Pickart 17 Dec '08

17 Dec '08

Hello, VDR (1.6.0-2) crashed after stuffing the syslog with: vdr: [24126] ERROR: possible result buffer overflow, dropped 13 out of 13 byte vdr: [24126] ERROR: possible result buffer overflow, dropped 2048 out of 2048 byte A backtrace shows that the function cTS2PES::write_ipack (initially called from cTS2PES::instant_repack with Count=184) kept calling itself (from then on with Count=180 and the same "Data" pointer all the time). The variable "bite" was 4 on the first call and then 0 on all succeeding ones. It was a video pid being extracted, so the cVideoRepacker got called, and I suspect its "breakAt" return value lead to the "// should never happen" code that set "bite" to 0. Some state information from the cTS2PES instance: pid=1023 size=2052 found=2200 count=2052 cid=224 rewriteCid=224 subStreamId=0 plength=4194234 plen[0]=98 plen[1]=124 flag1=flag2=0 hlength=0 mpeg=0 check=0 mpeg1_required=mpeg1_stuffing=0 done=true tsErrors=2020124 ccErrors=697951 ccCounter=8 The high error counts obviously show that the received data (from DVB-S) was somehow defective (There were many "PES packet shortened" errors earlier), but ideally VDR shouldn't crash even when the data is broken... Can anyone please fix this issue? Greetings, Andreas

When I view BBCHD, ArteHD, AnixeHD or the AstraHD channels I don't encounter many problems. Image is clear and no stutter. But as soon as I watch the 1080i/H264 channels of my provider (Canal Digitaal) on Astra 23.5e, I have major stuttering. BravaTV in HD doesn't have much problems, but NGC HD and Discovery HD is an other matter. My Core 2 Duo just couldn't handle it with FFMPeg and Xine-lib 1.2. But since I've put in a Core 2 Quad, I'm able to watch those channels even with fast moving images :) >> I'd like to have full-HDTV on a single x86 mini-ITX board.

It needs to have the options you wrote. But I don't want a Popcorn or some other kind of device. I want the option to enhance it myself (flexability) so I'm waiting desperately for GPU based decoding of H264 and VC-1 transport streams :) Niels Wagenaar

VDR with S2API
by Klaus Schmidinger 15 Dec '08

15 Dec '08

The attached patch is what I've gathered from various postings regarding adapting VDR to the S2API driver API (thanks to Igor M. Liplianin, Niels Wagenaar and Edgar Hucek - did I forget anybody?). Since the S2SAPI doesn't provide a way of determining whether a DVB-S device supports DVB-S2 (at least I didn't find any), you need to apply the second attached patch to the driver in order to impelement a new capability flag that reports the availability of DVB-S2 support. If you don't want to patch the driver, you can change the line case FE_QPSK: frontendType = (frontendInfo.caps & FE_CAN_2ND_GEN_MODULATION) ? SYS_DVBS2 : SYS_DVBS; break; in dvbdevice.c to avoid FE_CAN_2ND_GEN_MODULATION. Either set frontendType permanently to SYS_DVBS or SYS_DVBS2, depending on what you have. So far DVB-S and DVB-S2 appears to tune fine. DVB-C is completely untested. With DVB-T tuning doesn't work, even though my TDA10046H based DVB-T card does work with the S2API driver under VDR 1.6.0. So for the moment I would appreciate if people could test DVB-T tuning and check whether maybe I made some silly mistake in the DVB-T tuning code. Klaus

Autosort-plugin
by Rene Hertell 14 Dec '08

14 Dec '08

Hi all! I'm using Hannos vdr-extensions repository for my Ubuntu intrepid ibex. I have for some time now tried to set up the Autosort-plugin without any success. According to the logs, the plugin starts, creates a bunch of groups (I'm using the example-config). But when it reaches the last group, vdr restarts: Here is my log: . .. ... Dec 14 14:32:15 vdr vdr: [18668] OSD: AutoSort: Creating Group 'WrongCa' Dec 14 14:32:15 vdr vdr: [18668] OSD: AutoSort: Creating Group 'Old Channels' Dec 14 14:32:15 vdr vdr: [18668] OSD: AutoSort: Creating Group 'Unsorted' Dec 14 14:32:15 vdr vdr: [18668] saved setup to /var/lib/vdr/setup.conf Dec 14 14:32:15 vdr vdr: [18654] text2skin: loading /var/lib/vdr/plugins/text2skin/Motz/Motz.colors Dec 14 14:32:15 vdr vdr: [18654] parsing /var/lib/vdr/plugins/text2skin/Motz/Motz.skin Dec 14 14:32:15 vdr vdr: [18654] text2skin: loading /var/lib/vdr/plugins/text2skin/enElchi/enElchi.colors Dec 14 14:32:15 vdr vdr: [18654] parsing /var/lib/vdr/plugins/text2skin/enElchi/enElchi.skin Dec 14 14:32:15 vdr vdr: [18654] text2skin: loading /var/lib/vdr/plugins/text2skin/Enigma/Enigma.colors Dec 14 14:32:15 vdr vdr: [18654] parsing /var/lib/vdr/plugins/text2skin/Enigma/Enigma.skin Dec 14 14:32:15 vdr runvdr: restarting VDR I tested also by uninstalling all vdr-modules, and running vdr just with the Autosort-plugin. Same result. I would appreciate any ideas, help etc that could help me getting Autosort to work on my vdr-box. Best Regards, René -=-=- ... No amount of planning will ever replace dumb luck.
