Decoder can't handle intra-only frame before a keyframe #780

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
vp9_decode_frame skips frames until it sees a keyframe:

  if (!pbi->decoded_key_frame && !keyframe)
    return -1;

This precludes the valid use-case where the first valid frame in an intra-only 
coded inter-frame.

A simple change to fix this, but we should also produce either a test vector or 
a unit test to make sure that intra-only coded inter-frames work as expected.
