IPP H264 encoder with RGB24 input leads to "inverted" video

[Aditya_Kadambi]

This issue was discussed before here:

http://software.intel.com/en-us/forums/showthread.php?t=80805

Here is the gist:

1. My Directshow input from a camera supplying YUY2 data.

YUY2 -> H264 encoder -> Video output.

The video output looks fine.

2. My Directshow input from a camera supplying RGB24 data.

RGB24 -> H264 encoder -> Video output.

The video output looks fine, but it is upside down ("inverted"). Obviously because of the default stride issues.

From the original thread, there doesn't seem to be any resolution:

So, is this the expected behavior?

I then tried to color convert using VideoProcessing class.

RGB24 -> Convert to YUV422 using videoprocessinf class -> H264 encoder.

No change. It still is upside down.

IPP is such a great tool! I wish I could know the reason for the RGB24 bevavior from the community and the Intel experts here!

Setting negative height obviously didn't work. I'll investigate more and report back.

Perhaps, I should use UMC :: Colorconversion?

Is this fixed in Update 7. I see this bug fix in the release notes:

umc_color_space_conversion plane inversion fixed
