Expand description

Retrieve features from the bitstream. The *features structure is filled with information gathered from the bitstream. Returns VP8_STATUS_OK when the features are successfully retrieved. Returns VP8_STATUS_NOT_ENOUGH_DATA when more data is needed to retrieve the features from headers. Returns error in other cases. Note: The following chunk sequences (before the raw VP8/VP8L data) are considered valid by this function: RIFF + VP8(L) RIFF + VP8X + (optional chunks) + VP8(L) ALPH + VP8 <– Not a valid WebP format: only allowed for internal purpose.
