JDFense. At all firmware with android 4.2.2 there is an unpleasant feature
video stutters on the network,a lot of streaming video and heavy rip. I think this is due to the fragmentation of TCP packets and slow MLC type NAND flash


How can you improve the reading speed of Nand?
Or reason to RAM?
Can I change the TCP buffer in init rc?

net.tcp.buffersize.default=4096,87380,256960,4096, 16384,256960? net.tcp.buffersize.wifi=4096,87380,256960,4096,163 84,256960 ?net.tcp.buffersize.umts=4096,87380,256960,4096,16 384,256960 ?net.tcp.buffersize.edge=4096,87380,256960,4096,16 384,256960 ?
We have different numbers.
I do not think that these values are optimal. Do you know?


we have:
# Define TCP buffer sizes for various networks
# ReadMin, ReadInitial, ReadMax, WriteMin, WriteInitial, WriteMax,
setprop net.tcp.buffersize.default 4096,87380,110208,4096,16384,110208
setprop net.tcp.buffersize.wifi 524288,1048576,2097152,262144,524288,1048576
setprop net.tcp.buffersize.lte 524288,1048576,2097152,262144,524288,1048576
setprop net.tcp.buffersize.umts 4094,87380,110208,4096,16384,110208
setprop net.tcp.buffersize.hspa 4094,87380,262144,4096,16384,262144
setprop net.tcp.buffersize.hsupa 4094,87380,262144,4096,16384,262144
setprop net.tcp.buffersize.hsdpa 4094,87380,262144,4096,16384,262144
setprop net.tcp.buffersize.hspap 4094,87380,1220608,4096,16384,1220608
setprop net.tcp.buffersize.edge 4093,26280,35040,4096,16384,35040
setprop net.tcp.buffersize.gprs 4092,8760,11680,4096,8760,11680
setprop net.tcp.buffersize.evdo 4094,87380,262144,4096,16384,262144

We will also wait for the news to the RC 3066 https://github.com/phjanderson/rkpatchomatic

Okay, you answer with google - not easy, but from russian to english google is much better than from russian to german.

Good question about network, but I have no answer right now, maybe another ROM Dev will answer.
Anyway I have to do more research in the 4.22 android stuff. Maybe I find some improvement for the network.

Have you had a consultation with a 900supersport
You used it ? http://www.freaktab.com/showthread.p...301#post111301

[JDfense]

I stay always in contact, but I have not used his toolkitchen so far.

JDfense

PS.: For my next ROM, I wlll try it.

[Iharambr]

Clear.
Leolas, you or any one of the developers to get loans from the users by making application apk (without using a terminal emulator) for it. http://www.freaktab.com/showthread.p...d-For-rockchip.

in a terminal emulator and it works.

[JDfense]

Could be an idea to create an apk for the dumping, but let us first built it in the rom see how it works, after that I ask Leolas, what he think about.

JDfense

[Iharambr]

OK.

[angelobiz]

i used dump_image.. and work great ( i try it on 3188)

in roms you can delete pynmee.apk..
it is a app for chinese keyboard

i wanted change kernel for delete overclock....:-)

[JDfense]

You try dump image on what?

Okay. I take it out.

JDfense

[angelobiz]

You try dump image on what?
JDfense

i try dump_image on clone of J22 with rk3188
and all work...
mmhhh in effect... i never try it on cx803.....
tomorrow i try it....

[Iharambr]

Finless system can install in the next firmware?

Check with dmesg which hardware you have. For the wifi chip you can cat /sys/class/rkwifi/chip (like MT5931)




For changing the Wifi you need to replace or add with that from your original ROM


/system/lib/libhardware_legacy.so (loads proper driver module)
/system/lib/modules/xxxxx.ko (use lsmod to find the proper one that is loaded, in case of MT5931 wlan.ko is loaded )
/system/etc/firmware/yyyyy (where yyyyy is the file needed for your specific hardware loaded by xxxxx.ko, wlan.ko loads WIFI_RAM_CODE )
/system/bin/netd
/system/bin/wpa_supplicant

[Iharambr]

I got a working ROM MK808b on CX803. http://yadi.sk/d/cT3wbf0qCauod
WiFi works.
Video is much smoother.
But the image in streaming video worse.
You can fix this? Point codecs?


improved video:
media.stagefright.enable-player=true
media.stagefright.enable-meta=true
media.stagefright.enable-http=true
corrected by false
persist.sys.use_dithering = 1corrected by =0
video.use.overlay=1

Now everything looks good!

JDfense you can use it for the next Rom.
Get a good Rom!
