I read in the mail I've pasted below that VDR did not support AAC.

Is this still the case? If so, could this be why I'm not getting audio in my recordings? Does anybody know of any patches / tweaks / changes I could use to enable AAC in VDR.

I don't understand why I get sound with live tv using streamdev, though given that I don't know the first thing about how the steramdev plugin works this isn't surprising.

Does anybody

Hi,

There appears to have been some changes made recently to BBCHD on 28.2E: -

BBCHD:BBC:10847:vC56M2O35S0:S28.2E:22000:2328:2330=NAR;2329=eng:2331:0:6940 :2:2050:0

It is now not watchable with a reel eHD card - no audio and stuttering video.

The Reel support people are saying this is possibly because they have started using AAC audio which is not supported by VDR.

Is anyone else having problems with this and FFMPEG or CoreAVC via xine or is it still fine?

Thanks,

Morfsta

Hi Scott,

Only that the file has no audio stream.

Opening a recorded file in mplayer I the following:

Playing /var/lib/video.00/Real_Life#3A_The_Great_Sperm_Race/2009-08-11.21.28.1-0.re c/00001.ts. TS file format detected. VIDEO H264(pid=250) NO AUDIO! NO SUBS (yet)!

I'm not sure how to debug this, would really appreciate some help in understanding what is going wrong.

Hi,

I'm setting up VDR using xbmc as a frontend as described here: http://xbmc.org/forum/showthread.php?t=45314&highlight=audio

I've got live streaming working well but have an issue with recordings where no audio comes through.

I am using mirak's VDR 1.7.7 from the repository here: https://launchpad.net/~mirak-mirak/+ppa-packages

Could this have something to to do with the audio used for NZ tv which broadcasts in LATM encapsulated AAC? I'm not sure why the streamed live tv would work fine and the recordings don't though.

Any pointers much appreciated.

Thanks, Alex

Anything in the xbmc log?

Thanks Christian. Based on your info I've found the following 2 threads:

http://forum.handbrake.fr/viewtopic.php?f=4&t=5715 - describes which PID is used for NZ AAC TV

and

http://www.mail-archive.com/vdr@linuxtv.org/msg10575.html - describes where in the code the PID id needs to go.

Fingers crossed a modification to pat.c to include looking for PID 0x12c may do the trick ...

My guess would be that since streamdev gives the whole TS to xbmc you can hear audio as long as xbmc knows how to handle it. When doing recordings however the PID filtering of vdr will be used and may omit the (to vdr unknown) audio track. This is just a shot into the dark but you could verify that by running mediainfo or something like that on the vdr file to see if it contains an audio track at all. If not vdr's PID filters would have to be modified to support AAC...

Best regards,   Christian

That seems to be the right approach, however I doubt that 0x12c is the right pid. Maybe you should get a copy of the TS from streamdev (just use wget on the streamdev url) and then analyze what you can identify there. I think it should be 0x11 for MPEG4-Audio...

You could also have a look at streamdev's pid filtering since obviously this is already working as expected.

I just did this for you and it seems 0x11 would indeed match what you're looking for, looking at streamdev/server/livestreamer.c:

case 0x11: // ISO/IEC 14496-3 Audio with LATM transport syntax
