How to use functions like I420ToBGRA ? #249

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Include <libyuv.h>
2. Use libyuv::I420ToBGRA
3. Function not found

What is the expected output? What do you see instead?
I want to use functions like I420ToBGRA. But this function is not found

What version of the product are you using? On what operating system?
iPhone

Please provide any additional information below.
I can use some functions like NV12ToI420, ... but I can't use some like 
I420ToBGRA. I see this functions exist, as in this 
https://code.google.com/p/webrtc/source/browse/trunk/src/common_video/libyuv/lib
yuv.cc?r=1151

I've included <libyuv.h> but the XCode says that this function does not exist

Can you provide the exact error message?

I see the function prototype in 
https://code.google.com/p/libyuv/source/browse/trunk/include/libyuv/convert_from
.h
and the function in
https://code.google.com/p/libyuv/source/browse/trunk/source/convert_from.cc

Also you likely want I420ToARGB, which is the most common 32 bit format.
BGRA is a big endian format, not commonly used; Most common occurrence is OSX 
format kCMPixelFormat_32ARGB

So I must include <convert_from.h> as well?

no, libyuv.h includes convert_from.h
Is the error that you can't find the header, a compile error, or a link error?
If you're using xcode natively, make sure source/convert_from.cc is in your 
project.
