BBC iPlayer broken on Intel Atom N270/NVIDIA ION 1/VDPAU with Flash 11 but no easy way to step back to Flash 10.1/10.2
I use a Lenovo Ideapad S12, running the spec above - Intel Atom N270 (single-core 1.6GHz CPU), NVIDIA ION 1 GPU, Ubuntu 10.04, VDPAU loaded from repos...
I have accepted all Flash upgrades... but recently the BBC updated iPlayer to start requiring use of Stage Video logic in iPlayer (for those outside the UK, iPlayer is basically as critical to end-users as Hulu would be in the States). Hardware Stage video acceleration was available as experimental code between Adobe Flash 10.1/10.2 and 10.3.183.10 for Linux, and in the beta releases for Flash 11, *but was ripped out of the release version of Flash 11 for Linux*.
The upshot of this is that while the GPU is used for h264 DECODING, the CPU is left on its own to render the video content... which, on a netbook of the above spec, is maxed out pretty much on Youtube, never mind iPlayer. However, iPlayer now presents the video transport information when you mouseover the video playback window - it requires CPU that there just isn't available. Video freezes with no recovery - audio continues. COnfigs such as Core Duo/Intel X3100, being software-only - doesn't have the issue, but it DOES peg the CPU at around 50-60% on both cores - as was the case in Flash 9 or before.
Youtube stutters badly; iPlayer is unusable for video. AUDIO, however, isn't a problem, running about 50% of available CPU on my netbook.
This has been reported to the BBC under case number 1084738, and referenced on http://
The BBC recommended backing Flash out to a minimum of version 10.1... however, there is no easy package to roll this back, due to the following situation.
1 - When Flash 11 came out, the Flash 10 package was updated directly, rather than a Flash 11 package rolled in and adobe-flashplugin repointed.
2 - The most recent version of the one other package - flashplugin-
A bug was raised to request Flash 10.3 to be made available (as I would have expected it to have been left so I could easily back out - this is #886302 on Launchpad). I don't know what "Wishlist" means - but IPLAYER IS BROKEN ON THE ABOVE SPEC.
This also affects 4OD, Probably Demand5
