Working HDMI passthrough.

[Finless]

I got a message from mo123 saying that you want to know how to patch your version of libmedia.so.
I'll see if I can put something together, I haven't worked with this in almost a year so I just have to refresh my memory first.
Sadly I just realised that all my posts over at minixforums.com is gone.
I had explained most of it there.

Good to see your still around!

DTS is actually working on the modded XBMC setup

Looks like the file I picked for DTS testing, one where I could switch between DTS and AC3 audio channels, is the culprit. Both formats on that file play on MX Player but the DTS channel causes XBMC to crash. I found a few other DTS files and they all play fine on the modded libmedia and XBMC.

Found a quick way to see if passthrough is active. When attempting to change the volume using the TV Box remote when a passthrough is active, XBMC would display a notice to that effect. Dolby HD and DTS indicates both as being passthrough, AAC 5.1 is transcoded (i.e I can change the volume on the remote). But I guess I am probably exporting coal to New Castle with this observation.

Maybe not, you can still view websites from a year ago through cached pages of other sites like

just viewed the old minixforums pages

... The hack was posted on the old minixforums.com, and that forum doesn't work anymore, been replaced by new minixforum.com. ...

You will find them also at the new forum (posted by HardwareGuru; BTW: I don't think he knows how to do the patch)

... Tried to compare a patched and non-patched libmedia.so, there are just too many differences...

I think the main problem will be to find a libmedia.so which is the one before the patch...
I think there exist ~7 different patched libmedia.so by him...

[no_spam_for_me]

The other information I can find is (only this)
"... All credits for the idea and the initial patch to stafstrom, I just changed the registers and addresses of the patch to make it work on our libmedia.so"
at http://allminipc.com/forum/viewtopic.php?p=3374&f=3

BTW: at the 1.5a for the x7 Bob also talk about the librkffplayer.so (at 11.)

Stafstrom has a post on XBMC forum, send him a message to disclose the libmedia.so patch, no reply.
The hack was posted on the old minixforums.com, and that forum doesn't work anymore, been replaced by new minixforum.com. Tried to compare a patched and non-patched libmedia.so, there are just too many differences. By the way SPMC 13.3.3 has been released but still based on Gotham.

HardwareGuru on minixforum and Freaktab and hillyu on Freaktab also know how to patch libmedia.so, but havn't received a reply back from them.

Yes, but only the parts at xbmc and also the link by Jakemate... but nothing about the way to patch the lib...

.......................but I do recall he disclosed the source code to this mod.

After reading Jakemate's post I decided to give the R89 another test. It has been powered down so after firing it up I tested the dual AC 5.1 DTS file and both sound channels came out good using the MX player. I did however noticed when switching between the two sound formats the switching to the DTS will sometimes create a message that DTS is not supported (then there would be no sound). Switching over to Kodi it would still crash when I selected the DTS channel. AAC 5.1 is still played in stereo using MX Player but it is played in SS only when transcoding is selected in Kodi. Trying to fast forward will still crash XBMC.

I realize that a good practice would be to power the box down after crashing so that all the SW could be freshly initialized??

Re: Working HDMI passthrough.

I think you mean libstagefright=on at the box with the modded libmedia ???
And then everything is fine?

Yes seems ok up to now. Prob is sd goes in slow motion when libstagefright is enabled.

Just got another beelink box delivered yesterday. Ive not changed anything on the unit just booted straight into the supplied version of kodi.

I turned libstagefright off and mediacodec on as I do on the other box with the hacked version of libmedia.so.

The new box crashes exactly the same as the one with hacked libmedia.so.

So turned libmedia on with the box with hacked libmedia.so and everything works, no crashes.

Do you see the same libstagefright messages in the logcat?

When you say - "no crashes", does that mean your videos play 'flawlessly' with the various formats of surround sound?
