<p>Systems and methods for determining whether a decoder can playback compressed video identified as being encoded with an operating profile and/or level unsupported by the decoder are shown Systems and methods are described for playing back video encoded as an elementary bitstream, where the elementary bitstream has a specified encoding profile and satisfies at least one playback condition A number of embodiments include a decoder that is incapable of playing back video encoded in accordance with the specified encoding profile The decoder is configured to locate the specified encoding profile within the elementary bitstream The decoder is also configured to determine whether the elementary bitstream satisfies the at least one playback condition in response to the location of the specified encoding profile within the elementary bitstream Furthermore, the decoder is configured to commence playback of the elementary bitstream based upon the determination that at least one playback condition is satisfied.</p> |
