does not play .mkv file

[rikardo1979]

can you post more details about the files what having an issues with ? mkv is just container info but would be helpfull if you can provide more details like codec, audio/video information, etc
in the meantime you can try change the RAM split from 100 to 128
so do the following from SSH

Code:

nano /boot/config.txt

and change the following

Code:

gpu mem 256=100

to

Code:

gpu mem 256=128

or if you have Raspberry Pi V2 with 512mb RAM

Code:

gpu mem 512=100

to

Code:

gpu mem 512=128
