Slow 720p playback

[smallsp...@gmail.com]

Hi all,

Was trying to get some 720P video playback on my BBB on a neat touchscreen monitor I got from here. Surprisingly the screen works pretty well after just plugging it in. However, when trying to playback 720p video through VLC (no audio), I've got some major latency, youtube suffers the same way.This is a generic out-of-the-box BBB from Adafruit (element14) on 3.8.13-bone47, Debian 7.

After doing some searching, I found: http://beagleboard.narkive.com/Ebgduatx/debian-sgx-v3-14-x which I thought would solve my issue (granted, this seems to be for 3D acceleration, I'm not sure how it would actually help me with playback, I'm just grasping at straws here). Unluckily though, it doesn't seem to be a simple as sudo apt-get update ; sudo apt-get install linux-image-3.14.15-bone6, 

My apt-cache search linux-image returns this (as you can see, no 3.14.

My sources list:

#deb-src [arch=armhf] http://repos.rcn-ee.net/debian wheezy main

I'm not particularly trying to create a 1080p media center or anything super graphically fancy with this, in fact I'd like to use the BBB because I've got uses for all the IO it has access to, but if I could play 720p video at 60 FPS (with or without audio is fine), then that would be ideal. 

I wouldn't mind downgrading to a different kernel version/switching distros either as long as I could take advantage of the IO still.

Does anyone have any advice for the next steps I should take here? Maybe a different video player? Some logs I could look at?

Thanks.

sgx doesn't do "video" acceleration... Only 3d....

Those directions are old:
