padr\u00e3o.\n<li class=\"l\"> Novos decodificadores adicionados: DFPWM, Vizrt Binary Image.\n<li class=\"l\"> Novos codificadores adicionados: pcm-bluray, DFPWM, Vizrt Binary Image.\n<li class=\"l\">

colorchart \u2014 gera uma tabela de ajuste de cores.\n<li class=\"l\"> multiply \u2014 multiplica os valores dos pixels do primeiro v\u00eddeo pelos pixels do segundo v\u00eddeo.\n<li class=\"l\"> pgs_frame_merge combina segmentos de legendas PGS em um \u00fanico pacote (bitstream).\n<li class=\"l\"> blurdetect \u2014 determina a desfocagem dos quadros.\n<li class=\"l\"> remap_opencl \u2014 realiza o remapeamento de pixels.\n<li class=\"l\"> chromakey_cuda \u2014 implementa\u00e7\u00e3o do chroma key que utiliza a API CUDA para acelera\u00e7\u00e3o.    <\/ul>\n<li class=\"l\"> Novos
