HE-AAC support (DVB-T)

[dman_lfc]

Good, can you put a small .ts recording of a channel on our ftp please?

Address: ftp.team-mediaportal.com

About 45-60secs should be good enough.

Cheers

Yep uploading now, could take a while though they are ~30Mb each at 128kbs
They are called:

For DMAN from mcraenz (C4) .ts

For DMAN from mcraenz (Tv One) .ts - This 1 might contain an AC3 audio stream as well; I know they were doing some testing with AC3.

ETA 1hour30mins!

I've been testing this as well, but haven't tried recording, just viewing directly with Media Portal as a client. I have had the AC3 streams working ok with TVOne and TV2, but obviously HE-AAC has been an issue on the others. With SVN 17500 TVOne and TV2 have stopped working, perhaps because TVE3 now recognises the HE-AAC stream.

Anyway, my reply with details and logs is in the SVN thread "TVEngine3 Snapshot: 02-24-2008 05-09h Revision 17500".

Will keep testing as things develop.

Thanks heaps for getting the work done to include this support!

Re-scan the channels to update the audio stream info.
Also set the client to prefer AC3.

No joy unfortunately. Tried both a rescan, which resulted in updated channels, and also deleted and rescanned from scratch, but I get the same result as before with the HE-AAC channels. For audio I've tried MPA, Cyberlink Audio Decoder, and ffdshowa and DScaler Audio Decoder. The best result I get is with Cyberlink which initially freezes video, but then if I fast forward to the end of the timeshift I get some pops and hisses, and video sort of plays.

I can post logs again if you like, or open to other suggestions? DVBViewer still plays all channels fine.

I think that's what you can expect as per:

TVServer will now recognize the channels correctly and record the LATM AAC audio streams.
Problem is parsing the audio through TSReader at the moment.

You can play the TVServer .TS recordings through the latest SVN release of VLC so at least thats something.

DMAN

However can you make a recording and play it back with VLC. ( I Was able to make a recording and play it back in graphedit = MPA+CoreAVC )

Yes but not with MediaPortal File Reader as the source filter.

OK build 17540 uses the LATM guid so non compatible audio decoders won't connect.
Therefore hopefully you'd have audio again provided you set the AC3 preference.
If you want audio for the AAC channels you'd need to find Mainconcept AAC decoder v7.6.0.24073 or later.

So although I can select the Cyberlink Audio Decoder in Media Portal client, there's no way I can get it to connect because of the "LATM GUID"?

I can get AC3 audio ok now on the original channels, it's just the HE-AAC channels which won't work, which is what I was hoping SVN 17500+ would allow and is going to be key for the New Zealand DVB-T channels as most of them use that.

I'll try to track down Mainconcept AAC decoder and give that a go.

Thanks

Correct
LATM AAC is not working yet only with the Mainconcept decoder.
