Hi, yes, a single meta is enough. Thanks.

BTW, I am still not convinced this will bring a lot. My current measurements
for h264 show that parsing takes around 0.2 ms, even on a slower Sandybridge
underclocked at 800 MHz. i.e. there are probably other hotspots to optimize. :)

What I mean is that, it's a good thing, but probably not as good as something
else. Anyway, that wouldn't require much time either.

I have not measured for MPEG-2. I have a pathological case where someone
decided to encode a different slice per macroblock. So, please also be careful
about what you intend to allocate.
