Description

In France, most DVB-T HD TV channels use EAC3 for audio and are not d├ętected during DVB-T adapter setup.

History

#1

Updated by Andreas Smas over 9 years ago

I need output from Tvheadend's muxdump feature to track this down.

#2

Updated by A600 - about 9 years ago

Here is Spain also DVB-T HD channels use EAC3 so with XBMC I get no sound. Attached is a Tvheadend's muxdump.

in France, we have High Definition channels, when i try to read these stream, sound doesn't work, there is no sound channel.

ex : TF1 HD

ex working channel : TF1

on other french forum, they modify channel.conf, here is PID who resume included stream per channel :

TF1HD: .... : 110+120:110+130+131:1281

110 => PMT
120 => video stream
130 => VF audio stream
131 => VO audio stream

here is the stream for the other HD channels :

TF1HD: .... : 110+120:110+130+131:1281
FR2HD: .... : 210+220:210+230+231:1282
M6HD: .... : 310+320:310+330+331:1283
ARTEHD: ... : 710+720:710+730+731:1031

this problem appear for every HD channel exept ARTEHD

This is not critical. Critical is for bugs that causes the app to crash.

#5

Updated by dav59 - almost 9 years ago

in dvb_support.h, there is the beginning of the description :

#define DVB_DESC_AC3          0x6a

for E-AC3, it's 0x7a

as described in ffmpeg forum dev : http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-September/052741.html

I'm wondering how I can make these changes, I have some skill in dev but it seems to be difficult to implement.

Is tvheadend just forward the stream, or make some modifications ... (I've seen some files parser.c)

#6

Updated by dav59 - almost 9 years ago

maybe by following this implementation :

  • Found in version set to fixed

Fixed in r5552

Note that this is announced over HTSP as a new audio stream type (EAC3) so XBMC must be modified
to handle this.
