* Linear sub-rectangle scaler for use in Chromoting.wez@chromium.org2012-01-141-1/+44
| | | | | | | | | | | | | | This implementation re-uses the common row filter procedures, but is currently limited to a C horizontal interpolation procedure. There's also plenty of scope for optimizing the new sub-rectangle scaler routine. BUG=93451 TEST=media_unittests, remoting_unittests and manual verification of image quality of Chromoting sessions using fit-to-screen.

* Cleaning up src/media to be consistent with static versus anonymous namespaces.scherkus@chromium.org2011-03-071-14/+10
| | | | | | | | | | | | | We were using a mix of both (and sometimes even static functions *inside* anonymous namespaces!) so we decided to stick to using static. Also moved static/test code into media namespace and removed media:: prefixes.

* RGB to YUV conversion using SSE2hclam@chromium.org2011-02-011-0/+31
| | | | | | | | | | | | | This code uses SSE2 intrinsics with the feature of 2x2 subsampling for U and V. Performance compared to a pure C version is about 20% faster with better quality.

* Remove deprecated CommandLine::GetLooseValues(), rename to args().evan@chromium.org2010-07-211-1/+1
| | | | | | | | | | | | | | | It returned a wstring, when really we wanted the native encoded strings. Fixing the majority of callers actually simplified them in many cases because the callers wanted native strings too. Since I'm touching every caller, I gave it a more useful name. I'm not sure where "loose" came from but it never made sense to me.
