If there are not enough bits to decode a frame, the function returns MFX_ERR_MORE_DATA, and consumes all input bits except if a partial start code or sequence header is at the end of the buffer. In this case, the function leaves the last few bytes in the bitstream buffer. If there is more incoming bitstream, the application should append the incoming bitstream to the bitstream buffer. Otherwise, the application should ignore the remaining bytes in the bitstream buffer and apply the end of stream procedure described below. The application must set @p bs to NULL to signal end of stream. The application may need to call this API function several times to drain any internally cached frames until the function returns MFX_ERR_MORE_DATA. If more than one frame is in the bitstream buffer, the function decodes until the buffer is consumed. The decoding process can be interrupted for events such as if the decoder needs additional working buffers, is readying a frame for retrieval, or encountering a new header. In these cases, the function returns appropriate status code and moves the bitstream pointer to the remaining data. The decoder may return MFX_ERR_NONE without taking any data from the input bitstream buffer. If the application appends additional data to the bitstream buffer, it is possible that the bitstream buffer may contain more than one frame. It is recommended that the application invoke the function repeatedly until the function returns MFX_ERR_MORE_DATA, before appending any more data to the bitstream buffer. Starting from API 2.0 it is possible to pass NULL instead of surface_work. In such case runtime will allocate output frames internally.
