[vlc-devel] [PATCH 1/2] avcodec: pass whole AVCodecContext instead of hwaccel_context only
Rémi Denis-Courmont

Sat Oct 27 12:02:30 CEST 2012
In current versions of libavcodec, VDPAU does not use hwaccel_context,
but it does use draw_horiz_band. Now vlc_va_Setup() can access and
modify the entire AVCodecContext.
TBD: This patch makes the width and height parameters redundant.
They should probably be removed too.
TBD: If libavcodec VDPAU support were normalized, this patch might
become useless.
