Working HDMI passthrough.

After a bit of tinkering and reading lots of freaktab posts I've managed to get hdmi passthrough working on my ubox r89 16gb.

I am using the latest beelink rom 110k4109

Both dolby digital and DTS are working, I'm using a marantz receiver.

Download and overwrite libmedia.so which is in /system/lib , I used esfileexplorer and set settings to enable root access. You can get the hacked libmedia.so from here;

https://drive.google.com/file/d/0B3xq_SNrT9Tqemh5MEMtXzNLOGM/edit?pli=1

Next download a custom xbmc that takes advantage of the libmedia.so hack. I used this Kodi release which you can get here;

https://mega.co.nz/#!3hoizbDC!wpeB1X1SnlipOZANSUP2cA99r3s8m0U_6rbHkqD-e3k

In android settings/sound/sound devices manager ensure it is set to HDMI Bitstream.

In xbmc set the audio output to 2.0 (setting to 5.1 causes lag on sd streams)

Enable passthrough checked.

Enable dolby digital transcoding is checked.

I restarted the whole system just to make sure, many thanks to Wasser for the hacked libmedia.so for kitkat and also Karel for the Kodi release to take advantage of libmedia.so.

Hopefully it will also work for you, if so maybe the changes in libmedia and also the modded xbmc could be merged with current software?

Hi, I just discovered your thread, any chance you still have the files saved cause the link are no longer valid

So its already included in the latest nightly build?

Good news. I'm in contact with Rockchip and they made the hack "official".
I'll test it tonight, but it anyway means no more manual patching, it should be builtin in coming firmwares

Good news in deed. However, which hack is it? Firmwares may come late, I'd like to have a test........

Will it be supported in Kodi or just SPMC....SPMC is the only one that i can get smooth playback right now.

Question when Kodi gets out of rc....will you update spmc and do the rk patching? how will that work?

Kodi Helix will probably get released next week.
It won't have the Rockchip patches, so you will need to use SPMC build on Kodi Helix for Rockchip devices made by koying, hopefully also next week or thereafter

FYI

Did a new test with the files from the PT folder(not the patched libmedia) and can confirm that passthrough with HDMI works with the latest Kodi nightly. However when I play a movie with DTS the receiver show the audio as DD. The fastforward is working sometimes. But if I play a movie with chapters Kodi just exits if I try to jump to the next chapter. The video is also a bit choppy. Think it will be good when Kodi gets stable and we get a Kodi SPMC :-)

I tested on Tronsmart R28 with 110k4 FW, with patched libmedia.so, I couldn't find the original version anymore.

- RKVideoPlayer and Kodi Beta1 PT patched work with AC3 and DTS
- SPMC (13.3.4) reproduces stuttering sound, but surround sound is indicated on the receiver

Currently no high-res sound is passed through (DTS-MA 7.1 -> as DTS, TrueHD -> Stereo). I am not sure if this was even supposed to work in the current version... Still I think this should be our ambition, since today almost every Bluray is mastered in HD audio.

Make backup first
