Memory usage with VFW H264

Post by chentalfb on Sun Nov 08, 2015 10:10 pm

Hi,

I decode multiple H264 streams from a single Win32 application, running on Win XP 32 SP3.
I use the VFW interface.

When I use the old version 7.20, the memory consumption was small (~20MB per 704x576 stream), but with later versions (including 1.6.5), the memory usage per decoder is much bigger (~60MB per 704x576 stream).

What is the reason for this high memory usage, and is there way to reduce it?

Please advise,
Chen

You could try disabling H.264 in ffdshow VFW interface and enabling decoding in x264VFW.

What are the differences between H264 decoder of ffdshow and x264?
Are they similar in performance?

I have never done any performance comparisons.
