I have a Thinkpad R500 running Ubuntu 14.04 with a Radeon HD3470 and it seems like it isn't able to play HD videos without stuttering.
I tried watching this demo video (setting Youtube to 1080p) in all major browsers (Opera/Chromium/Firefox) the video is only playing with massive stuttering.
Downloading the 1440p and 1080p version of this video via youtube-dl and playing it via VLCplayer is somewhat more fluent, but still with sporadic stuttering.
As load immediately goes up and CPU usage is 100% as soon as trying to play this video, I guess, that the system lacks hardware accelaration for video decoding.
Is a Core2Duo not capable of decoding HD videos without help of the GPU?
If not, I would assume that the GPU should be more then capable to play HD videos - is there any chance I can get hardware video decoding in Ubuntu with this setup?
