I have mad the necessary to create a PLi4 image and it was successful. The image is working.

It did on the box.

With Ubuntu 12.04:

in my home: mkdir pli40

cd pli40

mkdir sources

git clone git://git.code.sf.net/p/openpli/openpli-oe-core

cd openpli-oe-core

make

MACHINE=dm8000 make image

 

I cannot find the source (decoder.cpp) to make the patch for AC3+ (bypass=7)

 

Where are the source files ?

Can anyone give me an advice ?

 

Many thanks in advance.

You have installed the OpenPLi build environment. You want to patch enigma2. That is another repository.

i just noticed that when i manually select AC3+ audio track then this won't be saved. next time when i zap to this channel default audio track is back again. kinda annoying.. AC3 tracks preferences will be saved normally though. i guess some more code parts must be changed..

Or maybe just turnoff the 'AC3 preferred' option in setup?

btw, i never turn(ed) this option on. are AC3+ options you manually select saved for you when 'AC3 preferred' option is off?

You can find the patch some posts ago (page 8).

Then place the patch on sources folder or create a folder enigna2 on the same location where enigma2.bb resides.

Finally create a file named enigma2.bbappend (on the same location with enigma2.bb is ok) and add the following.

PRINC="1"
SRC_URI+="file://the.patch.name...."

Now build will have the extra patch.

Thank you athoik,

The compilation worked, a working image created, but the patch does not seem to be applied, or maybe the code of decoder.cpp

changed and the lines of insertion/deletion have changed.

I get a warning about the patch, but it seem to show the patch is detected.

Here the warning: WARNING: Getting checksum for enigma2 SRC_URI entry patche2.txt: file not found except in DL_DIR

 

The patche2.txt file contains this:

No other error is shown. Any clues ?

This patch by pass also works on dm8000.

[clweb]

Yes,  want to make it work for DM8000.

I regenerated the diff file as decoder.cpp changed since publication of the patch.

I will redo all the work and see if it works.  It should. I can test if the patch is applied  in the decoder.cpp generated after the image creation.

The problem is that you named the patch patce2.txt originally the patch named 0001-dvb-decoder.cpp-workaround-for-Dreamboxes-DD.patch

The important is the .patch extension.

So rename it and increase PRINC by one (eg PRINC="2").


PS. Here is Satdreamgr image that contains AC3+ patch.

[clweb]

Thank you athoik.

 

I managed to get what I want with a simpler way.

Installed Satdreamgr on my DM8000. VIa FTP tranfer engma2 (/usr/bin) on the PC.

Then install PLi4 on the box. Via Telnet : init 5 (to stop Enigma), then via FTP transfer Enigma2 from PC to box.

The via Telnet init 3 to restart Enigma.

It is clear that any online update may reinstall an unpatched Enigma2. But as all runs I will not make online updates.

 

The Satdreamgr is a nice image, but I miss the access to my plugins (Bitrate,Fancontrol,Sherlock, Letterbox Zoom)

via the blue key.

[athoik]

I think you get the same with long press. Anyway since this solution works for you its ok.

[MastaG]

Nice to see it being merged for Dreambox receivers after such a long time

However the patch I was using in my images also had this part as well:

I don't know if there are any receivers out there supporting hardware decoding of PCM?

[athoik]

Did you ever see a channel with PCM sound?

[MastaG]

I wouldn't know to be honest.. but using PCM audio on a dvb pes would be far from efficient I guess:P

Just got the patch a long time ago, but I forgot who sent it to me.

But since the aPCM case also has a ifdef for Dreambox, I guess the driver supports hardware decoding of PCM audio for dvb streams, so maybe they exist..

[Trial]

Hi,

PCM is often used in high res music files.

 

ciao

[athoik]

... and that is handled just fine using GStreamer, we know that.

So the question remains, is there any channel that uses PCM as audio?
