Compile FFmpeg aml for S912 ( Mecool K3 Pro)

[martos]

Hello all,

 

I buy an another box tv ( ... do not laugh please ... it's only my 3 .... )

A K3 pro with S912 aml soc ( 8 cores = 4c a53 at 1.5ghz plus 4c a53 core at 1 ghz, 3G Ram and 16 G Flash ) with a DVB T2 and DVB S2 tuner ( find promotion at 60 $ )

 

I play with android 7.1.1 and use ffmpeg , i make an transcode : ( French Channel M6 in DVB T2 in 1920x1080 )

ffmpeg  -i http://192.168.1.50:8001/+1:0:19:401:4:20FA:EEEE0000:0:0:0 -s 320x240 /tmp/test.mp4

and speed ( without hardware decoder / encoder , only software ) give :

Speed 1x !!! ( my other S905W with 4 cores in same test give Speed 0.65 )

 

So test last libreelec , crash at boot, some armbian lot of crash ( be carefull the dtb with K3 in the name could ne not the good because it's old version now use 201 ... more information after test )

So find a distrib with ethernet works

make an ffmpeg compil

test

ok what i need :

Armbian with kernel 3.14 ( for vpu + mali )

Works with ethx

Dvb drivers works

Tvheadend

gstreamer aml

NO kodi

ffmpeg (with HW it could works )

 

I am out of the home for 5 days, so i tri it after

Ok for the moment :

I put corelec CoreELEC-S912.arm-8.95.0.img and ONLY if i put gxm_q200_k3_pro.dtb in dtb.img , i can have dvb device. ( i try a lot of dtb file)

I install add-on : tvheadend, oscam , ffmpeg

I don't use kodi ( the device have no hdmi connection , just used with lan )

I can see my channel in the lan with vlc ( the linux drivers of dvb is not so good than the drivers in android, but it's works )

I can make an transcode with ffmpeg ( HD 1920*1080 to 320*240 ) with ffmpeg ( in software with bandwith at 300K ) , the cpu S912 is enough ( not the S905 )

But this type of distrib is closed i can't install the Web Gui E Transcoder.

 

So i must find how to find a armbian dtb who works with my device ( for the moment i can boot but no ethX lan and no dvb )

 

If you have some idea ...

Hi Martos

 

Did you ever get a working dtb file for Armbian (with dvb device)?
