Comment(by Markus Schulz <msc at antzsystem.de>):
i have problems with trunk at 20650 and vdpau with interlaced content, it
stutters alot:

it's curious that's almost 3 frames, perhaps it has something todo with
the ac3-encoder buffering.
if i switch the deinterlacing to progressive or view progressive content
it works fine:
'video_output' mean = '39997,32', std. dev. = '1577,19', fps = '25,00'
'video_output' mean = '39997,25', std. dev. = '49,07', fps = '25,00'
'video_output' mean = '39997,73', std. dev. = '269,19', fps = '25,00'
'video_output' mean = '39997,56', std. dev. = '900,24', fps = '25,00'
2009-07-07 21:26:16.818 NVP(3): 22800 progressive frames seen.
'video_output' mean = '39997,75', std. dev. = '75,89', fps = '25,00'
'video_output' mean = '39997,66', std. dev. = '87,85', fps = '25,00'
'video_output' mean = '39997,72', std. dev. = '1011,71', fps = '25,00'
'video_output' mean = '39997,67', std. dev. = '411,33', fps = '25,00'
2009-07-07 21:26:32.818 NVP(3): 23200 progressive frames seen.
'video_output' mean = '39997,63', std. dev. = '76,92', fps = '25,00'
'video_output' mean = '39997,26', std. dev. = '49,30', fps = '25,00'
it works fine without ac3encoder (disabled) for both interlaced _and_
progressive content.
any idea?
