Since TVNZ insist on still using AAC-HE LATM audio (thank you TV3 for providing a AC3 alternative audio track) and Syabas not making any commitments when they will release a firmware fix to play those files I set to finding a way (not in real time to be sure) of playing those files on the PCH.

Note this is still in experimentation stage (and though he is unlikely to read this, many thanks to Donald Graft, author of dgindex and now dgavcindex for taking some sample captures I uploaded, and changing his program to read this audio file format). Those who are game to try I would welcome feedback on their experiences.

Note also this is not a complete guide - much is left to the reader to work out!

1. Get dgavcindex from  dgavcindex You will need the Alpha 30 release that supports LATM audio
2. Open the ts file captured from your DVB-T card. Go to Audio, select the AAC-HC LATM/LOAS stream
3. Save the project and demux video. You should get 3 files  xxx.dga  xxx.avc (the video) and xxx.aac (the audio demuxed)
4. Fire up Winamp and open this aac file. You should get audio. I am using Winamp v5.54
5. Get hold of the Winamp File Output plugin (go to the winamp site and look for plugins)
6. In Winamp Options/Preferences/Output choose the File Output plugin
7. Play the file again. It will output the file as a wav file
8. Use besweet or the gui belight to convert this wav file to ac3 (make sure you retain the sampling rate of 48Khz)
9 Get hold of  tsmuxer Get the gui if you can
10 Open the avc and ac3 files you have now. This part I am not sure you have to do and I doing further experimentation on it. In the audio delay area insert a delay of 1000ms (it seems to be constant)
11 Mux the files back as a ts file

And you're done - you have a ts file that now has ac3 audio rather than aac and the PCH plays it fine

Good luck!

Larry

Actually all we need is for Syabas to update the firmware in the PCH to handle AAC-HE LATM audio and we are done. You can integrate the PCH with a PC using gbpvr.

Now if TV1 and TV2 go HD and surround sound they will transmit in AC-3 audio (as TV3 does) and all this mucking about I described will be unnecessary since the PCH can play the TV3 streams natively.

I use a USB Hauppauge 900H DVB-T tuner with gbpvr which works well.

Have you tried TS4NP. That remuxer just takes your TS file (with LATAM audio) and outputs a copy (another TS file) that you can play in the PCH. Its a single step process, which sounds like it might be easier than what you are doing now. 

 

Sorry Ichiu7 - ignore this, I was thinking of something else. TS4NP will not work in this situation...

 

Cheers Mike

You answered your own question!  AAC-HE LATM audio is so new that few freeware products support it. PowerDVD8 does and I think sub uses an open source filter from Monogram to process it in gbpvr. I think that same source was used for DBViewer.

I was lucky enough to catch the attention of Donald Graft who wrote VirtualDub and also DGIndex and now DGavcindex, when he had access to source streams that I captured in this format, was able to effect a 20 minute code change to handle them.

Roll on TV1/TV2 using AC3 I say!

Hi Larry,

Yes - roll on AC3.  Actually I have a problem even playing non HD audio through the PCH from GBPVR. Whilst the picture quality is excellent, I can only get sound on DVB-S TV3 and C4 in the PCH.  TV1 and TV2 (via DVB-S) just will not play audio at all using TS MUX however it works fine with an MPEG mux. Unfortunately though, the MPG mux in unstable for me (i.e. sections repeating themselves etc).  So, my PCH is in the cupboard for the time being. Pity really. 

There is no simple answer is there. 

You know, I have a Sony RDR-HX1010 Recorder under the telly with 400GB of disk. That thing is on 24 x 7 and I never have to reboot it or deal with sound or picture issues. It has a clean simple Linux interface and it just goes.  The recordings always play and fast forward/reverse always work. The picture or sound never jams. There must be a lesson in there somewhere eh!  Of course it does not handle HD!!!

Cheers Mike

hi Larry, any chance you've been able to refine the process - to make it batch callable.  I'm guessing the main problem is the winamp conversion.

I wish :-(  But at the moment I am struggling with the TV1 HD broadcasts - can't seem to even see the AC3 stream in them. I suspect by the time I have it all worked out, the new firmware for the PCH will be out Surprised

you'd rescanned?  I just did that today and there is a "TV ONE" and "TV ONE(AC3)"  - this is what the gbpvr channel source tool reports to me.

Yes just did that and found the TVOne (AC3) channel. So it looks like it should be okay now. So perhaps when TV2 goes HD also we won't have to worry about AAC-HE audio anymore since if TV3 is any example, even if they transmit stereo, it's DD format.

That actually works fine for me. Can record and watch about 1 minute later so sort of time slipping. Voice is in sync and 5.1 sound.

Remember AC3 sourd tracks normally show up on the PCH as the 2nd soundtrack in the file, so you need to hit the audio button to switch to what the pch thinks is DTS.

Thanks for the tip - that will be the trouble. I did notice it flashed up sound channel 2.
