9 * VP8 in Cedrus shares same engine as H264.
10 *
11 * Note that it seems necessary to call bitstream parsing functions,
12 * to parse frame header, otherwise decoded image is garbage. This is
13 * contrary to what is driver supposed to do. However, values are not
14 * really used, so this might be acceptable. It's possible that bitstream
15 * parsing functions set some internal VPU state, which is later necessary
16 * for proper decoding. Biggest suspect is "VP8 probs update" trigger.
