H.264 BP decoder supports streams up to Level 3. In case of a H.264 bitstream of higher profile or level is encountered, as an error resiliency feature, error is not reported right away, the decoder attempts to decode the stream. Only when decoding is not possible (for e.g. because of unsupported features like B frames, insufficient number of available frame buffers), the decoder will report error.
