Mediaplayer Homecinema huge gpu memory usage

Post by ioana on Fri Apr 11, 2014 6:06 pm

I notice that my Mediaplayer Homecinema is using about 4-500 mb of gpu memory, and sometimes even 800mb when playing videos. I went on google but no info was found about this.

bsplayer and smplayer use 10mb video memory when playing an hd movie, and mediaplayer use 150-300 mb on single monitor, and 4-500mb or even 800mb if i have 2 monitors.
tested on this one, http://www.dvdloc8.com/clip.php?movieid=12167&clipid=3 ... but on all videos( avi, mpeg, mp4, etc) are the same.

on this video, http://www.dvdloc8.com/clip.php?movieid=12167&clipid=3

on single monitor, 1280 resolution, ati 6970 gpu 2gb video memory, fx8350 octacore cpu.
dvbviewer - 170mb video memory ( from what i know dvbviewer is build on mediaplayer classic )
mediaplayer homecinema - 150 mb video memory
windows mediaplayer 12 - 100 mb video memory
smplayer - 10mb video memory
vlc - 85 mb video memory
bsplayer - 9mb video memory

Memory usage depends on the rendering method. The more advanced video renderers use buffering to improve playback stability (less chance of frame drops and stuttering). The more frames are buffered, the higher the memory usage.

MPC-HC allows you to choose between renderers. See Options > Playback > Output. A basic renderer like VMR-7 will use very little memory, while madVR can use a lot. By default MPC-HC uses EVR Custom, which is an extended version of the plain EVR that WMP uses by default.

Your card has plenty of memory, so it would be a waste not to use it.

The only strange thing is that a second monitor increases the usage. I don't get any memory usage above 250 MB with two monitors (extended desktop). Are you cloning the desktop and thus showing video on both screens?

yes, i use my tv and my PC in the same time...extended mode. But i have movies only on one, on other one i play games or stay on web. if i exit mpc-hc video memory dropped down to 100mb.
When both( tv and lcd) are conected and on one i put an video with mpc-hc, video memory doubles.
Last night its the first time i notice that because win7 send me an message, that windows desktop has problem:

The Desktop Window Manager is experiencing heavy resource contention.
Scenario : Video memory resources are over-utilized and there is thrashing happening as a result. Reducing number of running programs and open windows may help resolve this condition.

The Desktop Window Manager is experiencing heavy resource contention.
Scenario : The Desktop Window Manager responsiveness has degraded.


The Desktop Window Manager is experiencing heavy resource contention.
Reason : Graphics subsystem resources are over-utilized.
Diagnosis : A consistent degradation in frame rate for the Desktop Window Manager was observed over a period of time.



And i tested even old mpc version, 6.4 or something, and others, like 7.1. The same.

That is certainly not a common issue with MPC-HC. My suggestion would be to update your graphics driver.

Did you perhaps overclock your GPU? That sometimes can cause weird problems.
