You need to add a new sepolicy rule in plat_file_contexts that allows bootplayer to run on the system..

/system/bin/bootplayer       u:object_r:bootvideo_exec:s0

Bumerc,
It didn't work! Is there somewhere else to edit or add code?

how did you do it?

[james739]

how did you do it?

I edited plat_file_contexts in system/etc/selinux and added

/system/bin/bootplayer            u:object_r:bootvideo_exec:s0

bootplayer has following permissions in system/bin/
owner:root
access:reand and write
group:root
access: read-only
Others:
access: read-only
execute: Allow executing file as program (checked)

In build.prop

service.bootvideo=1
persist.vendor.media.bootvideo=3050

bootvideo file is in system/etc/

Hi,

I don't know if it matters or not, but I put the code in vendor/etc/selinux/vendor_plat_file_contexts.

/vendor/bin/bootplayer u:object_r:bootvideo_exec:s0

in build.prop,

service.bootvideo=1
persist.vendor.media.bootvideo=3050

And last and not least, make sure bootvideo has the correct permissions :
owner: root
access: rw
group:root
access ro
others:
access: ro


This worked.

Thank you for pointing me in the right direction.

I edited plat_file_contexts in system/etc/selinux and added

wrong, you have to insert this line in afck/bc-tool/system/selinux/plat_file_contexts, all contexts files that are in this directory will be compiled to file_contexts.bin during the build process and passed to the e2fsdroid as build parameters, old Contexts files are overwritten..
but I'm glad that it worked

@james739 is bootplayer from there working on Android 9? i want to change it too
@bumerc so for any modifications i need to make a folder with mod? if i add/replace files manually in extracted partitions then build them it won't work, right?

[bumerc]

drakulaboy
You don't have to create a mod folder, only if you absolutely want it, if you want to automate something. Otherwise it is enough to make the changes by hand

[drakulaboy]

bumerc so, for example i want to add video bootanimation, i copy/paste the file bootplayer to bc-tool/system/system/system/bin/bootplayer then i add

/system/bin/bootplayer u:object_r:bootvideo_exec:s0

to afck/bc-tool/system/selinux/plat_file_contexts , edit by hand init.amlogic.rc from afck/bc-tool/vendor/vendor/etc/init/hw and add

service bootvideo /system/bin/bootplayer /system/etc/bootvideo
class main
user root
group system
disabled
oneshot

save it, then in terminal i do , make mod-partition-all

make mod-partition-all
mkdir -p "bc-tool/stamp"
cd bc-tool/odm && ./build
check source folder...
ok
sepolicy sha256sum: don't match, please apply mod-sepolicy!
make: *** [build/mod.mak:62: bc-tool/stamp/.stamp.mod-partition-all] Error 1

hmm, okay then i do make mod-sepolicy
all good , then i do make mod-partition-all again
and here it fails to pack the system partition full log here https://pastebin.com/raw/Z3ZERs6B
make mod-system fails too with the same error

btw: build.prop - what file should i edit from system or from vendor?

---

okay, i tried to unpack and edit another .IMG , it's good

[bumerc]

drakulaboy
You make it difficult for yourself, just use the standard player, leave out everything you have done and only make these two entries in build.prop

system build.prop:

service.bootvideo=1

vendor build.prop

persist.vendor.media.bootvideo=3050

copy bootvideo mp4 to /vendor/etc/ and recompile the partitions

[drakulaboy]

bumerc thank you, i've read all 5 pages and now i know for sure how it's working, i know russian too so there is no problem with messages from terminal, and the boot video animation is working now

[bigthinks]

Thanks tools. But I meet that errors when make mod-vendor:

./build: line 100: contrib/mke2fs: cannot execute binary file: Exec format error
generate fs_config
compile file_contexts.bin
./build: line 106: contrib/sefcontext_compile: cannot execute binary file: Exec format error

create a sparse img...

Install Ubuntu 64bit version, binary is 64bit

I found some program unsure what it is on the pine firmware site on the wiki page. Its like 104G!! i figured it was something to build android firmware or edit or something over my head.

This is what it says

Android SDK

Android P SDK [v9.0]

• Direct Download from pine64.org
  • MD5 (TAR-GZip file): 1EAC08942E238293E3AF11C7890DF307
  • File Size: 104.34G

I think this is the link if it works

Umm... that is ROCKCHIP and this is an AMLOGIC forum thread. So that should have been posted in a new TOPIC for Rockchip devices.

What you found is the "Source Code" that is specific to the ROCK64 device, so if you have the device you can build the Android 9 software on a Linux/Ubuntu machine with the Pine64 SDK.
( sdk = software development kit )

There will be software tools to modify or package Rockchip firmwares in the Source Code, if you want to try your hand at development and make a custom ROM for the Rock64 then that would be the only reason to download the SDK.

Cheers
