Its possible to add ac3+ codec for dreamboxes images because spanish provider is going to change codec.

[athoik]

This must be done in the drivers, you need to open ticket to DMM.

the hardware needs to support it!

[antrabe]

Its already working in some open pli images but you have to tune in a HD channel with ac3 downmix off and then zapping to ac3+ audio channel and it works. Its not hardware issue is license problem not payed by dmm

Sounds like a bug to me. Anyway, OpenPLi can't do anything about this.

[antrabe]

openpli could add if audio ac3+ downmix off if not downmix on? maybe solve the issue i dont know because im not specialist coder.

 

thanks a lot of for your support 

[Erik Slagter]

Downmix is implemented in the driver...

[antrabe]

Hemertje do you think that its not supported by the hardware it was implemented by you no? On broadcom chip specifications its supported handle ac3+. Could be created a patch to install it to enable ac3+ on dmm boxes? Thanks for your support

[littlesat]

It needs to be in the drivers..

AC3+ works on DM8000 with PLi3/4. The stream is only available via DVI/HDMI cable (as found in AC3+ specifications) not the digital coax/optical output.

You must switch to a channel with AC3 output (HD channel or Pro7 on Astra) then switch to the channel with AC3+.

It works nice with the french DVB-T HD channels wich have only AC3+ sound.

i have dm8000 end of 2010  but doesnt works i dont know if there is any change on last models that have other hardware. Maybe im doing something wrong. when i install the last openpli i cant do anything because the user password has changed  can you tell me which is by default. i will try today again

My Dreambox is from 2009.

With the last PLi the password should not be a problem.

Try with empty password, or with the default : login: root, password:dreambox

The drivers need to support the advertised functionality. This will (a.o.) depend on a manufacturer willing to pay licence-fees.

[Erik Slagter]

[pieterg]

does not seem related, libdvbsi++ does not provide codecs

[antrabe]

Which file should be modify? And where codecs introduced?

[pieterg]

Codecs are hardware and drivers.
Nothing you can change.
