RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - CK1one - 2012-09-26 So lets try to get a odroidx for gimli (2012-09-26, 07:44)gimli Wrote:(2012-09-26, 04:06)lundman Wrote: gimli RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - Shivansps - 2012-09-26 (2012-09-26, 02:40)Shivansps Wrote: Well empatzero build is a proof of concept only,(i think this is the lib that gimli rejected) i give it a go and well... it performs much better killing x11, but UI fps at 720P is around 40fps and 18-20fps at 1080P, considering the low idle cpu usage that has be running on hardware, im not sure if that what we have to expect from an Mali-400 single core.OK i quote myselft to correct... i was wrong, i double check my mkv files and some are in mpeg-4 not h.264, wrong label, sorry. Big Buck Bunny, both 720 and 1080P are running in Cedar Decoder, not software, 1080P lags because of low FPS from mali GPU. The problem here is called MALI-400, Cedar lib apears to be OK, aside from the fact that it does not support some codecs that his Android version do... At 1080P Mali-400 is just not fast enoght(-20fps), causing problems, video go too slow (Big buck Bunny lags in 1080P, and is using cedar). Something is really wrong with Mali-400 in the A10... or if is really this slow it will be a BIG problem... Like im playing the video, i try to go to the UI, is slow as hell both the video and UI, i go to see system info and the CPU usage is below 30% but the thing is running at 9fps... It works much better in 720P. Its obiusly a GPU performance problem. The XBMC crash for me at start of some videos for no reason, im cheking and those videos are all using MP3 audio codec, after that decided to test with mp3 music and it crash too, so the problem is around MP3 decoder in xbmc. BTW on the last screen, check "Sumary" and "Free Memory" thats whats happens when i playback something, sections of the screen jump up and down, and it gets worse depending on the video. No idea of what the problem is, i asume its Mali related too because sections of the UI moves up and down too whiout playing anything. RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - cristatus - 2012-09-26 I am new to this forum so not sure about the development status of XBMC on mk802 but here I am to share my experience about the empatzero's build. I have successfully cross compiled it with few adjustments to the rootfs and depends.mk file and built xbmca10.deb once the build is complete. Installed on a lubuntu from miniand and I was surprised with the result. Let me say, even though empatzero claims it 0.0.1 (alpha), I admit it's quite usable. The XBMC UI is responsive and showing around 43-45 fps at 720p mode. Regarding the video playback, initially it crashed with a 1080p movie (h264 mkv). Then I tried couple of 720p and they played flawlessly so I assume it's using CedarX (Shivansps, how can I make sure it's not SW decoding). Then I again tried 1080p video, it crashed. I was so excited of the result that I gave it another try and surprisingly this time it played 1080p too without any major issue (some flickering initially). This is really a great news. Looking forward for some official words from xbmc team...

The firmware is not an open source but the APIs are well opened. So it sounds like that is all possible. RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - rellla - 2012-09-26 I follow this thread for a while, also arm-netbook irc and ml. Great to hear that something's going on. I'm new to crosscompiling but I already managed to compile the parts (uboot, kernel etc.) and create a bootable sd-card with an debian rootfs for my mele. To go on with compiling an testing the xbmc, mali and x11 stuff I'd be glad to get some hints, where to find some help about a right set-up for a cross-compile-environment and howto do the thing itself. I'd prefer to get a sid-armhf as target-system, crosscompiled in a sid-amd64 virtual machine. Although using and playing with linux for years, I'm still a bit confused and unsure about mixing compilers, debian and ubuntu binarys etc. on different systems (Of course I know, thats not the best idea to use armel-bins on i386 ;-). So I'd be glad to get some hints where to find further information. Perhaps it would be also practicable do a short entry in the wiki.... Thanks and sorry for hijacking the thread.... rella RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - Shivansps - 2012-09-26 (2012-09-26, 11:42)cristatus Wrote: I am new to this forum so not sure about the development status of XBMC on mk802 but here I am to share my experience about the empatzero's build.

Installed on a lubuntu from miniand and I was surprised with the result. The crash issue is because of libmad on dev enviroment, those videos are probably using MP3 audio. As for SW or HW rendering, play a video and then open /home/(user)/.xbmc/temp/xbmc.log, search for "A10", and see if its failling or opening... But right now it only supports H264 and MPEG2, but its not a cedar problem.

I have tested again with debug option enabled. All the three small HD movies I played previously worked till the end. The debugging info shows FPS between 16-25fps and 35-50% cpu usages (during video playback). It's same for both 1080p as well as 720p movies. The log file does mention Cedar usages, here is a portion of the log file: Code: 21:39:03 T:1230066752 NOTICE: Opening video stream: 0 source: 256 RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - Shivansps - 2012-09-26 Well dvdplayer is rendering on Mali, thats why is slow, and if you have a 720P resoution there should be no diferences in a 1080P or 720P movie. Im still wondering about the "jumping"... ill have to use 720P hdmi resolution and try...

Good that i choosed i different route for my implementation RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - Shivansps - 2012-09-26 Well we cant expect a Mali-400 single core to have enoght power to render a 30fps 1080P movie (it can barely render the UI at a not so decent fps). Im not even sure that the Broadcom GPU on the Raspi will be able to do so...

Its still not the GPU (Mail 400) thats doing the rendering, its the VPU; http://linux-sunxi.org/CedarX (which is able to decode 2160p, thats quadHD). Second, I suggest you read what the Mali 400 is capable of; http://www.arm.com/products/multimedia/mali-graphics-hardware/mali-400-mp.php RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - davilla - 2012-09-26 rendering GUI is not the same as rendering a yuv video. please don't confuse the two. RE: Allwinner A10 : Is XBMC ported to MALI-400MP ? - jompan87 - 2012-09-26 Ofc not, should had made that clear |
