1. A method for determining that a decoder configured to decode a picture in a bitstream conforming to a first profile is capable of decoding a first picture in a bitstream conforming to a second profile, wherein the first profile is a still picture profile and the second profile is a video profile, the method comprising:

obtaining an indicator value, the indicator value indicating conformance of the bitstream to the first profile or the second profile;

determining whether the first picture in the bitstream is a still picture; and

responsive to the indicator value indicating conformance of the bitstream to the second profile and the first picture is determined to be a still picture, determining that the decoder is capable of decoding the first picture in the bitstream conforming to the second profile.
