Q: The videos don't load at all on sites that are SWF 10 and above.
A: Gnash does not support SWF 10(+)/ActionScript 3(AVM2). If you want a
support for the latest Flash versions, use Lightspark!
A more up-to-date version of Lightspark (0.5.0 vs 0.4.6) can be obtained via
this PPA:
https://launchpad.net/~sparkers/+archive/ppa
Do not forget to also install the 'browser-plugin-lightspark' package which
does not come along with Lightspark installed.
Q: Also, is there hardware acceleration?
A: Gnash supports hardware acceleration (VA-API, OMAP, Xv) but it is disabled
by default.
Q: ...the performance was much smoother with Adobe.
A: Use YouTube with HTML5! You can activate it on
https://www.youtube.com/html5.
This thread is meant as a reaction to the previous thread about Gnash where I
does not found a satisfiable answer. I does not wanted to start another
discussion about it, just wanted to share that there is a proper way to
install it!
I personally use Gnash/Lightspark + JDownloader(the best non-p2p downloader
available) + some HTML source tinkering to watch Flash videos.
Also, there is a YouTube alternative which does not use Flash. It is called
Stagevu an you can visit it's homepage on http://stagevu.com/ (requires Totem
+ GStreamer plugins to be installed).
