audio not demuxed

[lankou]

Hi Neuron2

I just got a new recorder dvb box, this box records in trp format.
This trp format can be read by dgindex, which is great. But the problem is
that although the video is correctly demuxed, audio is not.
I am using the latest dgmpgdec 1.5.8

I uploaded a small extract at :
http://rapidshare.com/files/402097390/dvbtry.zip.html

If you have some time to give a look.
Thanks in advance,
Lankou

There is MPEG audio on PIDs 0x82, 0x83, and 0x85.

To select one for demuxing do this:

Stream/Detect PIDs: Raw

Select (highlight) one of the PIDs above

Hit Set Audio

Make sure Audio/Demux all tracks is selected.

The audio will now be demuxed.

Your stream does not contain PAT/PMT tables, so the audio is not automatically set. If you can enable them, do so.

I ran it through ProjectX and audio is present

The audio will now be demuxed.


Hi Neuron2,
Thanks for your answer. It is working pretty good !
Is there an option to select all audio tracks and process them at one ?

Your stream does not contain PAT/PMT tables, so the audio is not automatically set. If you can enable them, do so.

I have no idea how to do that. On the documentation I got with the box, it is written that the stream is directly written to the USB device without
any dvb box processing. I could not find anything in the dvb box menu.
Thanks a lot,
Lankou

[lankou]

I ran it through ProjectX and audio is present



Hi,
Thanks for this. Indeed, projectx is a very good tool. Everything is
demuxed at once !
In September, in my area, HD TV will be coming. Can projectx be
used also to demux mpeg4(H264) ? or is it only mpeg2 ?
Thanks for telling me about this tool!
Lankou

[netmask]

ProjectX is only for MPEG2 unfortunately. Not sure if OoZooN is planning any changes. I don't read German but there is an active forum at http://forum.dvbtechnics.info/forumdisplay.php?f=16

[neuron2]

Is there an option to select all audio tracks and process them at one ? Not in DGIndex. But it is supported in DGIndexNV.

Can projectx be used also to demux mpeg4(H264) ? or is it only mpeg2 ? For your information, DGIndexNV will handle H.264, MPEG2, and VC-1.

[kypec]

For your information, DGIndexNV will handle H.264, MPEG1, and VC-1.
:confused: Didn't you mean to say MPEG-2?

[neuron2]

A brain fart. Thank you for the correction.

Neuron2 and Netmask,
Thanks a lot for your valuable information/help.
