xmltv2vdr.pl
by Dominic Evans 14 Aug '15

14 Aug '15

I don't know if anyone else still uses the xmltv2vdr.pl perl script for piping XMLTV data into VDR's epg, but I've been keeping a version of it updated with some additional function here: https://github.com/oldmanuk/xmltv2vdr These are the changes since the last version (1.0.9) was released on the mailing list - Add support for XMLTV episode-num. Currently gets added as EPG entry 'sub-title', if no existing subtitle has been found, in the form sXXeXX (e.g., Bones~s01e01). - Change default SVDRP port number to 6419. - Better support for ATSC/PVRINPUT EPG sources. - Allow multiple channels to have the same XMLTV channel id, useful for multi input (e.g., DVB-T, DVB-S) systems where you want to feed VDR the same info. Previously only a 1:1 mapping was permitted. I've also received a pull request from someone who rewrote the whole script to be a lot more readable and to use full XML parsing (rather than just line-by-line scraping), but I still need to investigate what the performance penalty is before accepting that in.

VDR & Multiple frontends
by Eddi 25 Jul '15

25 Jul '15

Hi, I wrote a patch to Steve Toth hvr3000 repository, so my FlyDVB Trio can use multiple frontend. So I get: /dev/dvb/adapter0/demux0 /dev/dvb/adapter0/demux1 /dev/dvb/adapter0/dvr0 /dev/dvb/adapter0/dvr1 /dev/dvb/adapter0/frontend0 /dev/dvb/adapter0/frontend1 /dev/dvb/adapter0/net0 /dev/dvb/adapter0/net1 The bus of the two frontend is shared, isn't possible to get access to both frontend simultaneously, so I get an -EBUSY error by trying accessing frontend1 if frontend0 is in use. VDR doesn't support yet the second frontend, and it try to get exclusive access on both frontend on start, so the second frontend is inusabile. Vdr should probe for multiple frontend at start, and access frontend only on channel change. Please can someone give me an help to wrote a patch for this issue? Best Regards, Eddi

cSoftDevice::StillPicture() not updating video in VDR 2.0
by Marko Mäkelä 31 May '14

31 May '14

After upgrading to VDR 2.0, I got Softdevice to almost work (see the mail archive a couple of months ago). Sometimes it is showing garbage (really random noise) on the MGA350 OSD layer; I can live with that, as this box is only used for infrequent recordings. The last annoying problem is that going to the next or previous I-frame when editing (buttons 4 and 6 on the remote control) are not updating the video screen at all. Only the edit mark is moving on the OSD layer. If I press Play, it will start playing from the current edit mark. So, it is possible but much more clumsy to cut recordings. SoftDevice is overriding the method with this: void cSoftDevice::StillPicture(const uchar *Data, int Length) { SOFTDEB("StillPicture...\n"); if (decoder) decoder->StillPicture((uchar *)Data,Length); } It seems to me that mpeg2decoder.c in softdevice is creating a new thread every time I try to move editing mark, and calling cMpeg2Decoder::Action(). In gdb, it will fail as follows: while(ThreadActive) { while (freezeMode && ThreadActive) usleep(50000); BUFDEB("av_read_frame start\n"); if (useAVReadFrame) ret = av_read_frame(ic, &pkt); else ret = av_read_packet(ic, &pkt); if (ret < 0) { BUFDEB("cMpeg2Decoder Stream Error!\n"); if (ThreadActive) usleep(10000); continue; } useAVReadFrame=true, so it is calling av_read_frame(). That will block when running under gdb, like this: #2 0xb68f83a9 in cSigTimer::Sleep (this=0xb2c121f4, timeoutUS=50000, lowLimitUS=0) at sync-timer.c:75 #3 0xb68f1cf0 in cMpeg2Decoder::read_packet (this=this@entry=0xb2c120f0, buf=buf@entry=0x87fc5b0 "v\253T)\251z\366\020[\231a\202\275\237@\006\266\067k*r\370JV\255\364\020\177\247:\353 \004\024\277\004jhjG|] t$X", buf_size=buf_size@entry=10864) at mpeg2decoder.c:1128 #4 0xb68f1dcf in read_packet_RingBuffer (opaque=0xb2c120f0, buf=0x87fc5b0 "v\253T)\251z\366\020[\231a\202\275\237@\006\266\067k*r\370JV\255\364\020\177\247:\353 \004\024\277\004jhjG|] t$X", buf_size=10864) at mpeg2decoder.c:1042 #5 0xb69140c9 in fill_buffer (s=s@entry=0x85ac040) at libavformat/aviobuf.c:319 #6 0xb6916ff7 in get_byte (s=0x85ac040) at libavformat/aviobuf.c:365 #7 get_byte (s=s@entry=0x85ac040) at libavformat/aviobuf.c:360 #8 0xb6958984 in find_next_start_code (header_state=0x8a075e0, size_ptr=<synthetic pointer>, pb=0x85ac040) at libavformat/mpeg.c:142 #9 mpegps_read_pes_header (s=s@entry=0x89f2080, ppos=ppos@entry=0xb10cc190, pstart_code=pstart_code@entry=0xb10cc160, ppts=ppts@entry=0xb10cc170, pdts=pdts@entry=0xb10cc180) at libavformat/mpeg.c:246 #10 0xb695933a in mpegps_read_packet (s=0x89f2080, pkt=0xb10cc290) at libavformat/mpeg.c:419 #11 0xb690c3b4 in av_read_packet (s=s@entry=0x89f2080, pkt=pkt@entry=0xb10cc290) at libavformat/utils.c:591 #12 0xb690ce8b in av_read_frame_internal (s=0x89f2080, pkt=0xb10cc304) at libavformat/utils.c:998 #13 0xb68f2527 in cMpeg2Decoder::Action (this=0xb2c120f0) at mpeg2decoder.c:1228 It will unblock when I hit 4 or 6 again, because the thread would be killed (ThreadActive=false) by this: #0 cMpeg2Decoder::Stop (this=this@entry=0xb2c120f0, GetMutex=GetMutex@entry=false) at mpeg2decoder.c:1545 #1 0xb68f2cec in cMpeg2Decoder::Clear (this=0xb2c120f0) at mpeg2decoder.c:1655 #2 0xb68ea1b6 in Clear (this=0x83d3130) at softdevice.c:492 #3 cSoftDevice::Clear (this=0x83d3130) at softdevice.c:484 #4 0x080cf2da in cDvbPlayer::Empty() () #5 0x080cf7e9 in cDvbPlayer::Goto(int, bool) () #6 0x080d1303 in cDvbPlayerControl::Goto(int, bool) () #7 0x080fd676 in cReplayControl::MarkMove(bool) () #8 0x080fdcc6 in cReplayControl::ProcessKey(eKeys) () #9 0x080aac39 in main () I wonder why this worked in VDR 1.6 but no longer in VDR 2.0? Is it because Softdevice is expecting a PES packet here instead of TS, or is it something else? Marko

Webvideo and vdr 2.x segfaults

Hi, Is anyone using succesfully the Webvideo-plugin with vdr 2.x (eg. 2.1.6)? I just get vdr to crash with a segfault when i pick any of the video-sources (Google, Metacafe, Youtube etc) :-( I am using the latest git-source from git://projects.vdr-developer.org/vdr-plugin-webvideo.git René

Invalid sat cable number errors
by Ville Skyttä 24 Apr '14

24 Apr '14

Hello, I see errors like the below on every VDR (2.0.6) startup and apparently exactly 30 minute intervals after that in syslog: ERROR: invalid sat cable number in '[apparent binary junk]' The binary junk varies, today it's been for example '<C0><C0>ۙ>^?' and '<C0>0<BE><A4><8F>^?' as shown by "less". Any ideas what would be causing this or if I could do something to help debug this further?

EIT related crash with 2.0.6
by Ville Skyttä 17 Apr '14

17 Apr '14

Hello, I'm seeing an EIT related crash of VDR 2.0.6 every now and then, no idea if there's a way to trigger it on demand somehow nor do I know when exactly it happens; I just sometimes find a core file for it. gdb backtrace attached, my VDR is quite a patched one (the one from Fedora) but the line numbers appear to make sense for vanilla 2.0.6 too.

skipping 5/10 seconds
by Peter Münster 17 Apr '14

Hi Klaus, What about adding a possibility to skip ±5 or ±10 seconds when replaying a recording? Would you perhaps accept a patch for the developer version? That would be nice. -- Peter

still image at end of replay
by Peter Münster 13 Apr '14

13 Apr '14

Hi, Here a little feature request: Problem: the children are watching a recording, and at the end VDR switches to normal live TV, that can be anything. I have to be there at the right moment to turn off the screen and the sound, in order to bring them to leave the tv-room. I would be nice, if VDR could turn off the sound at the end of a replay and show a still image (e.g. "Children, go to bed now!"). What do you think about that? -- Peter

[Announce] epgsync-1.0.1
by Frank Schmirler 11 Apr '14

11 Apr '14

Hi, I just released epgsync-1.0.1 on http://vdr.schmirler.de. I've added a new option to schedule a resync every X hours and you may now use the SVDRP command "PLUG epgsync SYNC" to trigger a resync (this has always been possible by sending the SVDRP command to open the mainmenu, however that was undocumented and probably not obvious). Have fun, Frank
