OLD - USE NEW POST - MK808b FAQ's, includes 1080p

[Abducted]

I received a MK808 yesterday from a friend. With Finless 1.7c ROM (using the kernel that came with it) i also has some video problems under XBMC (with HW accel version). It would not always play smooth and it looked like sometimes it would display parts of previous frames mixed in with the current frame. Kind of like video corruption except those "corrupted" parts were normal looking parts from a few frames earlier.

After i flashed to the 2dark4u kernel all this was solved.

Also if you say it's an HDMI driver problem (if that even is the case), that would mean it could be fixed in the kernel.

mk808b users have to wait for 2dark4U kernel so no solution for us...

You realize I am using an mk808b right?

And I happen to be the most fussy person in the world when it comes to video playback?

So you're in 5% (including me) who actually could see microstuttering...

Afraid not, the only stuttering I have is due to video resolutions/bit-rates/gpu usage, all of which can be fixed on my end, and mostly intentional on my behalf to push the media capabilities to the limit.

I'm not saying there are not devices out there which don't have problems, but it really could be anything, from the TV, the rk3066, to the software.

If my mk808b had micro stutter every few seconds however, and I couldn't fix it, it would be under a car's wheel before it knew what hit it, so I understand where most people who have this problem are comming from.

Place in /system/lib/ using a file manager with root permissions, like this one.

Original included.

libstagefright.zip

Struggling to get this to work m8 .... I extract to where you say but it will not allow me to overwrite the existing files .... any suggestion?

[Abducted]

I have a feeling it's not going to work that way. Why else would leolas make a CWM zip file to update the libstagefright.so if you could simply replace it using a filemanager.

Does it keep 'reinstalling' after every reboot?, after a reboot, check the XBMC data is still there in /android/data/org.xbmc.xbmc/files/.xbmc/userdata.

Yea it does, everything Ive added on to it/downloaded (skins blah blah) get wiped.

Ive also tried using just straight Frodo 12.1 for Android and same thing. This is on a mk808b for anyone else. Never had a problem with playback or audio, just gui settings being reset/wiped

Are you using a file manager with root permissions as ididmytime instructed? /system is mounted read-only by default and you have to remount it as read/write in order to replace this file. If you can't find that option in your file manager, install Android Terminal Emulator, start it and type...
su
...and allow it root access. Then type...
busybox mount -o remount,rw /system
...Then try replacing it again in your file manager (don't exit Terminal Emulator yet). If it succeeds, go back to Terminal Emulator and type...
chmod 644 /system/lib/libstagefright.so
...Then reboot your device.

I don't see a recommendation for Minix Hybrid v2.2.2... not recommended at the moment?

[Abducted]

I think it's because ididmytime tested XBMC under both ROMs and performance when using the minix hybrid was very poor.

BTW i tested the updated libstagefright.so yesterday and i didn't do whole lot of testing, but while i could play 1920x1080 perfectly with the previous version now it started to play with artifacts and would crash XBMC. 1920x1024 did play fine (which it also did with the previous version). So maybe the new version has a problem with video resolutions that aren't devidable by 16.

[ididmytime]

I have a feeling it's not going to work that way. Why else would leolas make a CWM zip file to update the libstagefright.so if you could simply replace it using a filemanager.

Because having a .zip is much quicker and easier then manual placement. The zip contains all the libs, and is much less hassle. You could make a .zip with the fix, but how many people actually use CWM for these devices? It shouldn't take more than a few moments to replace the file.

That .zip contains the same libstagefright.so that is in Finless 1.7, so it will have the corruption problem.

What rom are you using? does it also reinstall on exit without a reboot?

If you use the file manager I suggested, it won't overwrite. Just rename the file and then copy it over. You don't need to set rw to the root filesystem, as this is done automatically when granted root permissions.

Very strange, I have been using it ever since I found it could be used on 1.7 without issues.

The normal one would green screen and reboot on certain streams, no such problems with this one. Are you using the 2dark4u kernel? It seems the GPU is being lowered to 433mhz in 1.5 when released, maybe it has an issue being so high?

Edit: That reminds me, when messing around with scripts today, I was testing out that live stream fix. It gives errors you wouldn't see if you ran it at boot, so I'm not convinced it is actually working/doing anything at all.

I just compared the files inside your and leolas's zip file and it seems the one that you've called libstagefright.soORG is the one Leolas has in his zip file. Are you sure you're not just replacing one libstagefright.so with exactly the same (older) version?

Also i tested on my MK808 yesterday and there is only a 433mhz GPU kernel available. On my UG007-II it runs at 466Mhz. So it cant be that.

About the script: Did you read the end of the first page and the 2nd page of my thread? Wizzy also had some problems to get it to work. But it did work eventually.

It will be the same, as the ORG bit means Original, that file is only there for backup purposes incase you want to swap back to the default libstagefright.so instead of the modified/new version.

Edit: About the script, it seems it wants to copy the two additional files to the XBMC folder, but has problems and doesn't do it.
