Initial vdpau surfaces buffer pool patch (7.68 KB, patch)
2010-07-08 13:14 UTC, Ahmed Ammar 		none Details | Review

Description Ahmed Ammar 2010-07-08 13:06:54 UTC 
On smaller devices (Such as ATOM330+ION), CPU consumption reaches 100% due to the constant allocation/deallocation of VDPAU surfaces (video and output). 

After discussions with satis on irc it was decided that a buffer-pool/cache was needed to improve performance.

A patch will soon follow from myself.

N.B. there's a left-over g_print in the patch.
Comment 3 Carl-Anton Ingmarsson 2010-07-30 09:44:05 UTC 
I've now commited a big patchset that should cache the buffers. Please report if it works to your liking.
Comment 4 Edward Hervey 2013-07-17 06:26:21 UTC 
vdpau has moved to VideoDecoder class and uses a buffer pool. Closing as obsolete.
