Problems with mkv media files. - Alex - 09-18-2014

I have had a lot of problems playing .mkv files on vlc media player, the only player that sort of worked was the Kaffeine player, but there was always a loss of sound synchronization - this could be adjusted 'on the fly' using the left and right arrows in quick succession. but a bit of a pain.

I think that the problem maybe that my computer just does not have the RAM for it (the media file was ~3.8Gb I only have 2 GB RAM)...would I be correct in that assumption? And is there anyway that I could use a USB drive or part of my HD as  'temporary' RAM?'.

I used to have the same problems with this type of file on Win XP as well, which indicates that it is not a problem with LL.

Thanks

Mine does not struggle but I get good service from the  ati driver on mine.

Code:
$ inxi -G
Graphics:  Card: Advanced Micro Devices [AMD/ATI] Wrestler [Radeon HD 6250]
           Display Server: X.Org 1.15.1 drivers: ati,radeon (unloaded: fbdev,vesa)
           Resolution: [email protected]
           GLX Renderer: Gallium 0.4 on AMD PALM GLX Version: 3.0 Mesa 10.1.3

Maybe go into Settings>Install additional drivers may help you?

Also. 

I use "mpc" & "mpd" on low spec gear to play movies.

mediaplayer via command line works OK for me also.

As long as it works. I ignore the errors.

Thanks rokytnji, i;ll try all those out and report on my efforts. meanwhile, I obtained another copy of the same movie but this time an .mp4 file of only 800Mb. It played fine on Kaffeine, but something strange has happened to my VLC player: it shows a display of many superimposed 'ghosts of other scenes on top of the main one:

Re: Problems with mkv media files. - Alex - 09-19-2014

I did try additional drivers, but it told me that there were none available. Next I tried Mediaplayer but it told me that i had it, but I cannot find it. MP2 did not work for at all ...I think that I am doing something wrong there.

But I did re-install VLC and now it works perfectly. I must have fiddled with some of its settings.

But I do appreciate your help, even though I was unable to make full use of it - I'll get it all , one day lol!

I'm the first to admit I don't know jack about much of anything but I doubt RAM has anything to do with it.  I've played 40GB BluRay movies on my computer and I only have 4GB RAM.

Re: Problems with mkv media files. - N4RPS - 09-26-2014

Hello!

Your statement is correct. The whole file is not loaded into memory before it begins to play.

I may be wrong, but perhaps increasing the size of your /swap partition, if possible, may help with this?
