Thanks.

Are there instructions how to build Android Nougat with DTV support like VIM2_Nougat_vTV_V170930?
You only need to patch the DVB Patch and build android update image again.
# cd ~/$Project/uboot
# make distclean
# make CROSS_COMPILE=aarch64-linux-gnu- kvim2_defconfig
# make CROSS_COMPILE=aarch64-linux-gnu-
# cd ~/$Project
# source build/envsetup.sh
# lunch kvim2-userdebug-64
# make otapackage -jN
Can you advise how to apply patch? As I can see in the archive it contains diffs to the files, probably those available on regular Nougat image GitHub.
# copy device-khadas/0001-DVB-add-support-for-DVB.patch ~/$PROJECT/device/khadas
# copy device-khadas/0002-DVB-add-build-config-for-VTV-application-KVIM2.patch ~/$PROJECT/device/khadas
# cd ~/$PROJECT/device/khadas
# git am 0001-DVB-add-support-for-DVB.patch
# git am 0002-DVB-add-build-config-for-VTV-application-KVIM2.patch
This patch fails:
device/khadas/0001-DVB-add-support-for-DVB.patch
All other patches succeed.
Problem is that device/khadas/0001-DVB-add-support-for-DVB.patch is not corresponding to kvim/init.amlogic.board.rc file that is on GitHub.
You can modify this file manually.
I will verify it tommorow because I’m not at office now.
Modified manually, but stuck on build error:
Update:
This error is shown when patches were applied on never built sources. Make sure to build kvim2, then apply patches and rebuild again - then it succeeds.

It doesn’t matter about DVB patch. Maybe you need to check your PC host environment.
This is how I solved:
If patches were applied on sources that were not built yet, build fails on mpeg part. If it was built before applying the patch, it worked.
Anyway, I have another issue - VTV app fails channel search - whether it’s automatic or manual, as soon as it is initated it stops and comes back to start window of app. The same happens with VIM2_Nougat_vTV_V170930 firmware.
I have tried with DVB-T (Lithuania) antenna plugged in.
And one more thing - can I make VTV app not autostart when Android boots up? I want to launch it myself when wanted.
I didn’t find the issue from built error message provided by you.
The amffmpeg don’t matter about DVB Patch. Maybe you need to provide more build error message for me.
Thanks.
@Frank.DTV Can you answer this question? Thanks very much.
hi Gytis
Anyway, I have another issue - VTV app fails channel search - whether it’s automatic or manual, as soon as it is initated it stops and comes back to start window of app. The same happens with VIM2_Nougat_vTV_V170930 firmware.

---- I will check and give you reply soon
And one more thing - can I make VTV app not autostart when Android boots up? I want to launch it myself when wanted.
----- I will add one setting option to let user can choose auto start or not for next version release.
Sorry for that. You can download fixup_dvb.7z to fixup it on VIM2_Nougat_vTV_V170930. The instruction file ReadMe is inclued in fixup_dvb.7z
Also I have updated the DVB_Patch for it.
Thanks, applying current version of DVB_Patch (or to be specific - 0003-DVB-fixup-application-quit-abnormal-while-DVB-T-T2-C.patch) solves the issue
I was able to build Nougat with Google Apps, SuperSU and VTV I ran DVB-T scan in Lithuania, got the channels found and it works. Also tried recording broadcast - all smooth.
However:
It does not support AC3 audio streams (both decode and passthrough fail for us).
– AC3 audio need license from Dolby, for S912, need S912-B chipset to support it.DVB-T/T2 and DVB-C does not work at all. I’ve tried to start search, but it quits immediately.
–can you help me to caputure the logcat information while DVBT/C channel search.
We really need a way to add AC3 support for audio stream. Otherwise there is not so much use having S/PDIF port
And one more thing - can I make VTV app not autostart when Android boots up? I want to launch it myself when wanted.
----- I will add one setting option to let user can choose auto start or not for next version release.
As I understand this will be solved. When can we expect new version? Any plans to open source it?
As yet we don’t have sources of VTV app probably there is no way how to integrate OSCam, Ccam or any other software based (CONAX-like) decoder? I have USB smart card reader which I would like to use for decoding DVB-C stream.
Along with other nice ARM-based devices I do have X Solo mini3 set-top box which runs on OpenPLI. Under this Linux-based system extensions are available (like OpenWebif interface) and one very valuable is softcams - OSCam can be added and it works very nice Can we have something similar with VTV app?
I saw there is Android build of OSCam (sources on GitHub) - this might be useful.
dear gytis
oscam is supportted already
please goto menu --> Installation --> DVB/S/S2. And then Input “999999” by remote control
it will open a hiden menu, then you will see CCCam, BISS there.

Thanks, I can access menu Now I need to figure the way how to add my cable provider keys from smart card. I’ll maybe have OSCam server running on my OpenPLI powered device and will try to get Khadas VTV’s CCam connecting to it.
Another issue DVB-C scan did not find any channels… Is it expected if all channels are encrypted? Shouldn’t they be found anyway? Channel scan set to All.
@Gytis
you can access oscam by internet browser : http://aaa.bbb.ccc.ddd:8888/ (aaa.bbb.ccc.ddd is your VIM2 ip address)
for DVB-C scan , can you give me more information, if you turn on scan type to ALL, it should found all channels (include scrambled channels).

I did turn on scanning for any channels and any type (radio or tv) but search found no channels Can DVB-C be somehow disabled by default in software?
I will try to find technical specification of my DVB-C cable provider.
