WebPPictureYUVAToARGB() doesn't work for View picture #178

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

* Call WebPEncode(config, pic) with pic being a YUVA view (pic->memory_ == 
NULL) and config.lossless = 1

* This doesn't trigger auto-conversion, but an error (NULL_PARAMETER) is 
reported instead.

Problem originates from WebPPictureYUVAToARGB(): this function has an 
unwarranted check for pic->memory_ != NULL

This happens for libwebp versions up to 0.3.1
