Abstract

em um exemplo, um dispositivo para recuperar dados de vídeo inclui um ou mais processadores configurados para receber dados que descrevem um tipo de entrada de amostra para uma amostra de um bitstream de vídeo, o tipo de entrada de amostra sendo uma de hev1 ou hev2, em que a amostra compreende dados de vídeo codificados de acordo com uma de codificação de vídeo de alta eficiência (hevc) ou hevc em camadas (l-hevc), e em que uma ou mais outras amostras incluindo dados de vídeo precedem a amostra no bitstream de vídeo em ordem de decodificação, e em resposta ao tipo de entrada de amostra sendo hev1 ou hev2 e a amostra compreendendo os dados de vídeo codificados de acordo com uma de hevc ou l-hevc, recupera a amostra para realizar acesso aleatório usando a amostra, sem recuperar os dados de vídeo de qualquer uma de uma ou mais outras amostras que precedem a amostra, e sem recuperar conjuntos de parâmetros de quaisquer amostras anteriores do bitstream de vídeo em ordem de decodificação.
