Re: [vdr] AAC LATM audio issue on dvb-t israeli service
by Barak Nahari 17 Aug '11

This issue have been fixed. Vnsi server developer Pipelka add a fix to the vnsi server plugin. Anyone who experience issue with aac latm should compile an updated version from the git. Thanks for all the help I've received from Klaus, Pipelka and the kind people here. Regards, Barak.

Currently, both AAC LATM and ADTS are unsupported by vnsiserver plugin. You can try enabling the support, but I guess the AAC demuxer is written for ADTS only... diff --git a/receiver.c b/receiver.c index 305af00..836c240 100644 --- a/receiver.c +++ b/receiver.c @@ -195,11 +195,15 @@ int cLivePatFilter::GetPid(SI::PMT::Stream& stream, eStreamType *type, char *lan case 0x0d: // ISO/IEC 13818-6 Sections (any type, including private data) case 0x0e: // ISO/IEC 13818-1 auxiliary #endif - case 0x0f: // ISO/IEC 13818-7 Audio with ADTS transport syntax case 0x10: // ISO/IEC 14496-2 Visual (MPEG-4) - case 0x11: // ISO/IEC 14496-3 Audio with LATM transport syntax DEBUGLOG("cStreamdevPatFilter PMT scanner: Not adding PID %d (%s) (skipped)\n", stream.getPid(), psStreamTypes[stream.getStreamType()]); break; + case 0x0f: // ISO/IEC 13818-7 Audio with ADTS transport syntax + case 0x11: // ISO/IEC 14496-3 Audio with LATM transport syntax + *type = stAAC; + GetLanguage(stream, langs); + DEBUGLOG("cStreamdevPatFilter PMT scanner adding PID %d (%s) (%s)\n", stream.getPid(), psStreamTypes[stream.getStreamType()], langs); + return stream.getPid(); case 0x1b: // ISO/IEC 14496-10 Video (MPEG-4 part 10/AVC, aka H.264) DEBUGLOG("cStreamdevPatFilter PMT scanner adding PID %d (%s)\n", stream.getPid(), psStreamTypes[stream.getStreamType()]); *type = stH264; BR, -- rofa

Re: [vdr] AAC LATM audio issue on dvb-t israeli service

After allot of help from Klaus to understand what was wrong i got a big break. Recording works in vdr with no issue at all, the recording do contain the aac-latm audio. After updating the vnsi server to last git and xbmc to last preEden build by Lars Op den Kamp all the channel watchable but still no audio. I'm no developer but i can read, on xbmc display it show that the audio is mpeg2 (which is not) and on the vnsi server code it's seems that the default is mpeg2audio. So i decided to force vnsi server to use the aac demuxer when mpeg2 audio is found, and at last i got audio working. I've posted an issue on vnsi-server github with more info about it https://github.com/pipelka/vdr-plugin-vnsiserver/issues/18 As you can read this in the issue i'm not sure where the problem or how vdr and it's plugin system works. It can be on the vnsi server plugin as it may can't recognize the aac-latm within the stream. It can be on vdr side if vdr tells vnsi server that the audio is encoded as mpeg2. Finaly it can be the trasport stream itself that misconfigured and have some marker indicate the audio as mpeg2. As my knowledge in mpeg2 ts and my analyzing skill are very limited i add the stream saved with tsreader so you may analyze it and also recording made by vdr. http://dl.dropbox.com/u/6902100/test13_001.mpg http://dl.dropbox.com/u/6902100/2011-08-15.01.27.1-0.rec.tar Thanks, Barak.

MaxVideoFileSize
by Dominic Evans 15 Aug '11

15 Aug '11

Apart from FAT16/FAT32/ISO 9660 compatibility reasons, are there any benefits to keeping MaxVideoFileSize for recordings at <= 2GB? I was considering setting it to something arbitrarily larger such as 16GB but just wondered if I was causing any unexpected side effects.

Re: [vdr] FreeviewHD channels.conf OK for xine, but not for VDR
by Chris Rankin 15 Aug '11

Now xine isn't tuning into the HD channels again either. Maybe it's a problem with the transmitter, but I'm thinking that the DVB userspace doesn't have enough support for DVB-T2 yet. Cheers, Chris

How to convert a JPEG image to an HD video frame?
by Klaus Schmidinger 14 Aug '11

14 Aug '11

The VDR plugin 'pictures' (part of the original VDR archive) uses a Perl script named 'pic2mpg', which converts a JPEG image into an MPEG frame that can be displayed directly by VDR's primary output device. This is done in essence by the command sequence jpegtopnm $Pict | pnmscale --xscale=$ScaleW --yscale=$ScaleH | pnmpad --black --width $SW --height $SH | ppmtoy4m -F $framerate -I p -S 420mpeg2 | mpeg2enc -f 3 -b 12500 -a $aspect -q 1 -n $system2 -o $Mpeg (see the actual script for the complete working environment). While this works fine for SD video, I can't seen to figure out how to make this work for an HD video output device. The video frame should be a 1080i frame in my case (my tv can't handle 1080p), but could optionally also be 720p or 1080p, depending on the actual tv's capabilities. Can anybody give me a pointer how this script could generate HD video frames? Klaus

eepg crashes VDR when analyzing a certain transponder on 19.2°E
by André Weidemann 14 Aug '11

14 Aug '11

Hi, I am currently running latest git of the eepg plugin to get EPG for the Freeview channels on 28.2°E. The satellite dish at my place points at 28.2°E and 19.2°E. Unfortunately the eepg plugin crashes VDR when analyzing a German transponder on 19.2°E during the EPG scan. Crashing can be provoked when switching to this channel: Sky Select,SkySel;SKY:12031:HC34M2O0S0:S19.2E:27500:2815=2:2816=deu@3,2817=deu@3;2819=deu@106:0:0:18:133:4:0 Syslog shows the following at the time of the crash: Aug 14 09:45:37 vdr vdr: [3729] PMT scan idle Aug 14 09:45:37 vdr vdr: [3729] EEPG: Premiere Extended EPG detected on pid b09.

FreeviewHD channels.conf OK for xine, but not for VDR
by Chris Rankin 13 Aug '11

Using scandvb with the "-o vdr" parameter is failing, but without it I get the following lines: BBC HD:554000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_256:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:0:0:17472 BBC One HD:554000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_256:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:0:0:17540 ITV1 HD:554000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_256:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:0:0:17604 Channel 4 HD:554000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_256:T Interesting. So xine is now receiving the stream via its DVB plugin, although it is also choking on the H.264 decoding. Still no luck getting the adapter's remote control working. Cheers, Chris
