Raspberry Pi2 and some video files

Raspberry Pi2 and some video files
Hi!
(sorry for my bad english)

I recently bought a new Raspberry Pi 2 (I don't have any other before this)

I am testing in last days with differents mediacenters, and now I love xbian, it's my favorite, but with all the other (openelec, osmc, etc.) have the same trouble.

What fails:
Some vids are very pixelated and appear stranges horizontal bars that decolore the real video image.

Where I found the issue:
This happens when the hardware acceleration for decode vids are enabled. If I disable the both options, the video looks great, but without the hardware acceleration plays with a very slow frame rate and some times stops some seconds.

What I try:
- Xbian, Openelec, OSMC in last versions
- Try to overclock
- I use a microsd class 10
- I bouth the two raspberry licenses for mpg2 y vc1, installed, and checked that appeare correctly enabled both.
- Not related with the size of the vid, because some vids of 16Gb play perfect and other than only 600Mb plays with the mentioned issues.
- The board is not overheat anytime.

At bottom of this post I attach two examples of the mediainfo for if someone can found the possible reasons, and say me if is hardware limitation, hardware failure, or if simply the actual mediacenter can't support yet this formats for rpi 2.

Thank you so much for your help!!

RE: Raspberry Pi2 and some video files
I will not work, sorry to tell you
It is High10 or 10bit video if you like. this is too much for RPi to software decode and there is no HW acceleration for this type of media

RE: Raspberry Pi2 and some video files
Thank you for your reply!

You think that in the future the rpi2 can be support this formats by HW with firmware update?

RE: Raspberry Pi2 and some video files
not easy to tell. you can better ask on Raspberry Pi Foundation.
my personal opinion is, it will not

RE: Raspberry Pi2 and some video files
Maybe, lately HEVC has made advances on the Pi 2 in software decoding. Perhaps Hi10 will be supported in the future, probably no higher than 720p though if anything.

Search the Kodi forums, you will likely find a few threads.
