How to Flash (Chrome or Firefox) hardware accelerated decoding? Something instead?

What can I do to get GPU to work on decoding Flash video?

At chrome://gpu Graphics Feature Status page I see all stuff green OK like Video Decode: Hardware accelerated, yet Flash nerd statistics tell me that decoding is done by software (yet rendering is accelerated).

I got not open source (additional) drivers for mobile ATI HD 7340. Had to change one Chrome flag to make rendering accelerated. What about decoding?

EDIT: I lowered CPU usage for Totem via Direct2D http://www.webupd8.org/2010/04/how-to-enable-direct2d-acceleration-in.html, but no changes in Flash.

UPDATE

For weaker hardware or decent hardware but desire for real 24 FPS web-embedded videos I suggest minitube-ubuntu, resoned below. Minitube can play videos from Youtube without using Flash and having Graphics User Interface, that is better decoding performance or less system resources taken for the action. I have also noticed difference in FPS (= no screen tearing or slideshow) while Flash was showing FALSE 0 dropped frames... The only problem I found is no Youtube account support, however subscribe works fine.

You can get minitube-ubuntu at Software Center.

gstreamer package or workaround may be needed:

sudo ln -s /usr/lib/kde4/plugins/phonon_backend /usr/lib/qt4/plugins/phonon_backend

.

For videos not hosted on Youtube there is youtube-dl supporting variety of sites. But without GUI, command termianl program.

Spec

CPU 2x 1700 MHz

APU AMD E2-1800 driven by fglrx-updates, VESA

Ubuntu v14.04

Chrome v36.0.1985.125

Flash v14.0.0.145 /opt/google/chrome/PepperFlash/libpepflashplayer.so

Performance

youtube.com HTML5 video 480p taking 70% CPU and false 24 FPS (I think Flash renders OK but Chrome FPS is lower and my eyes are not satisfied while screen is tearing)

minitube-ubuntu 1080p taking 70% CPU and true 24 FPS
