Transfer mode vs TS playback: any difference in TS streams for vdr.1.7.19?
by Laz 06 Aug '11

06 Aug '11

Hi, I'm currently updating the softdevice plugin to work with the changes to TS format that started with vdr-1.7.1 and also current versions of ffmpeg (libavcodec does the actual decoding). I've made some progress with vdr-1.7.19: Old PES recordings play fine (as I'd hoped they would!) New TS recordings play: the video looks fine. PlayTSVideo convertes to PES and passes that to PlayVideo of the output device (I assume it would be relatively straightforward to implement a proper PlayTs using avcodec but that's for a later date!). The sound is totally messed up: just lots of random buzzing noises (not looked into the audio yet). Tranfer mode does not work at all, all I get is a black screen and silence. Before I dig into buffers, etc., is there any difference between the streams sent to PlayTS in transfer mode and in playback? I see that transfer mode generates a PAT/PMT on the fly and passes the stream directly to PlayTs. Does a similar thing happen to a recording, i.e. the PAT/PMT is added before writing to disk and then the stream sent during playback is identical to that which would have been sent if it had been watched in transfer mode? Does the output device ulitimately receive the same set of PES packets? Thanks, Laz

I've used dvbsnoop to analyze my ts file. Audio stream of the first channel PID is 2562. PES PID of the from dvbsnoop is 0xc1 and state that is ISO/IEC 13818-3 or ISO/IEC 11172-3 audio stream. The audio encoded ac aac latm, is that means the the PES PID is set wrong in the stream ?

I'm not a programmer but i've done some reading, trying to understand what is wrong. I've looked in the vdr source and found that vdr should be recognizing the acc latm encoded audio, so the problem may not be in vdr. http://git.gekrumbel.de/vdr.git?p=vdr.git;a=blob;f=remux.c;h=c3f07fb7074754… For what i understand the aac latm should have PID 0x11. I've looked inside the vnsiserver source and didn't found any PID's only PES PID's. https://github.com/pipelka/vdr-plugin-vnsiserver/blob/7a964e109432ba00e8f9f… I'm was a little confuse how to convert the PID to PES PID So i've done a little googling and found this code http://code.google.com/p/mediainfococoa/source/browse/trunk/Lib/MediaInfo/M… it's seems that aac latm PES PID is 0xFA, unless i got it wrong, and i didn't found this PES PID on the vnsiserver code. I've tried to examine my ts file but couldn't export any info about the audio track, only that the encoding is aac latm. Is there is any more information regarding the audio track in my ts file? http://www.2shared.com/file/wEdFKfZy/test.html What should be my next step trying to understand where the problem?

Re: [vdr] HDHomerun and streamdev

I had the same problem until I downgraded to streamdev 0.5.0 and hdhomerun_atsc_firmware_20100828.bin. I am not sure both of these changes are necessary as I changed both at the same time. :( http://download.silicondust.com/hdhomerun/hdhomerun_atsc_firmware_20100828.… On Jul 16, 2011 6:00 AM, <vdr-request(a)linuxtv.org> wrote:

blacklisting providers
by Davide Chiarini 02 Aug '11

02 Aug '11

Hi all I was wondering if there is already a way, or a plugin, to 'blacklist' some providers from the channel updates. The fact is, I like to have channel updates set to 'new transponders' (there are often changes with my provider). However, this always leads to hardly manageable channel lists with literally thousands of entries. It would help if the channel updates could automatically discard/ignore certain pay-for providers that I'm not interested in (and could not view anyway, as they are encrypted),such as "polsat", arabsat,cyfra+. is something like this already possible? thanks davide

Hi there, I just published a new release of svdrposd at http://vdr.schmirler.de. The plugin publishes the contents of the OSD menu on SVDRP. It's primarily used by the remoteosd plugin. The new release fixes a minor bug which caused problems when using the svdrp4j Java client. Have fun! Frank

AAC LATM audio issue on dvb-t israeli service
by Barak Nahari 01 Aug '11

01 Aug '11

I'd allot of advancement setting vdr with dvb-t services, the last issue is aac latm related. I'm using vdr 1.7.18-11, vnsiserver plugin, streamdev plugin. Installed them from yaVDR testing-vdr ppa at https://launchpad.net/~yavdr I don't get any audio on xbmc using the vnsi plugin. On vlc i can get audio while playing the stream from the streamdev server. The audio seems to be encoded as aac latm. A link for the entire stream (saved with vlc) http://www.2shared.com/file/wEdFKfZy/test.html I've been googling a little and found a similar problem with NZ dvb-t service on the August 2009 archives http://linuxtv.org/pipermail/vdr/2009-August/021050.html Can this be fixed on vdr side? Thanks.

Re: [vdr] VDR Issues with DVB-T Services in Israel
by Barak Nahari 30 Jul '11

I've been looking in my syslog, http://pastebin.com/L3MmV7dh and found a segfault error, is it concerning xine decoding of the h264 stream? >From a quick googling it looks like this may be the problem. Is there's a way do get debug info from vdr and maybe to determine where the fault? When trying to play the stream i captured with vlc in mplayer i only get sound, is anyone can confirm that there is a problem while decoding the stream. My stream capture http://www.2shared.com/file/wEdFKfZy/test.html If so then will vdr remain unusable at all until a fix is patched to xine lib.

Different handling of back / menu keys
by Torgeir Veimo 30 Jul '11

30 Jul '11

The VDR menu key is somewhat under-utilised, it only toggles the menu on and off, I think it would be an improvement if it was combined with the back key. Instead of using the menu key to toggle the menu on and off, it could trigger the osd menu initially, initially, but would then subsequently work as a back key. So if you're deep in a menu, and you press the menu key, it would take you back one level, just as the back key does. If you need to go fully out, you long-press the menu key. This would mostly eliminate the need for a dedicated back key, and would simplify the basic menu navigation and make it more in line with other menu navigation systems (eg the ipod comes to mind). -- -Tor
