Bug 227038 – Very noisy logging on Youtube: (libvpx_vp9_decoder.cc:226): Failed to parse VP9 header from key-frame.

• Status: NEW
• Component: Media

Watch a video on Youtube with a debug build and notice this logging:
(libvpx_vp9_decoder.cc:226): Failed to parse VP9 header from key-frame.

printed out many times a second. It is super noisy and potentially indicative of something wrong with our logic (even though the video is playing fine) so I am filing a bug.

Eric says:
"""
We’re probably setting the key-frame flag when we shouldn’t before calling the codec
in decodeVP9DecoderFrameFromContiguousBlock()
"""

Code shows:
```
    // We set those values as VP9DecoderImpl checks for getting a full key frame as first frame.
    image._frameType = VideoFrameType::kVideoFrameKey;
    auto error = decoder.m_instance->Decode(image, false, 0);
```

We're indeed always setting the frame type to kVideoFrameKey.
