I'm investigating a crash in a complex application, so my apologies for
not providing a small repro case.
I'm decoding a H264 NAL stream with ffmpeg without any HW acceleration.
The pixel format is set to NV12. When attempting to decode the first
frame, I get a null pointer exception in ff_color_frame, specifically in
memset. ff_copy_frame is attempting to access frame->data[2], which is
null for NV12.
It seems that the function assumes that each color component corresponds
to one plane, which is clearly not the case for NV12.
