Sim! O Raspberry Pi 4 tem poder para reproduzir v\u00eddeos em resolu\u00e7\u00e3o 4K perfeitamente. Funciona? Depende! E por que isso? Como j\u00e1 inserido em conte\u00fados de tem\u00e1tica afim nos v\u00eddeos: “Pi OS Bullseye VPU: Youtube Acelerado? NetFlix, Disney+, HBOMax, Prime V\u00eddeo, rodaram? E Xbox Cloud?<\/a>” e como tamb\u00e9m no epis\u00f3dio anterior a este post “Raspberry Pi 4 N\u00c3O SERVE pra v\u00eddeos? Performance ruim? Veja isso! | GPU VideoCore P1 TimeLine<\/a>“, vimos que o porque est\u00e1 intr\u00ednseco ao investimento e amadurecimento tardio do SUPORTE ao equipamento pelos seus mantenedores oficial. <\/p>

\u00a0<\/div>

Pol\u00edticas, rela\u00e7\u00f5es comerciais, prop\u00f3sitos e outros aspectos podem tanto acelerar quanto retardar o processo de implanta\u00e7\u00e3o de um produto no mercado. Dito isto, ao longo de um tempo tenho buscado e garimpado informa\u00e7\u00f5es que dar\u00e3o a voc\u00eas a vis\u00e3o operacional da VideoCore VI 3D GPU contida no Raspberry Pi 4.<\/p>

\u00a0<\/p>

Hora com apresenta\u00e7\u00e3o detalhada como um raio-x da GPU (Unidade de Processamento Gr\u00e1fico) e do SoC (Sistema no Chip) hora com exemplos reais no mercado voc\u00ea saber\u00e1 detalhes sobre o funcionamento geral de v\u00eddeos no Pi4 bem como um comparativo real entre as capacidades do Amazon FireTV Stick 4K contra o Raspberry Pi.<\/p>

\u00a0<\/p>

Seja voc\u00ea da \u00e1rea de T.I. ou n\u00e3o vale a pena conferir o v\u00eddeo que \u00e9 uma vis\u00e3o geral de como funcionam as placas de v\u00eddeo para reproduzirem v\u00eddeos. Explica\u00e7\u00e3o simples e ilustrada para todos e principalmente aos usu\u00e1rios que desejam utilizar melhor os recursos de seus Raspberry Pi. Al\u00e9m disso, a l\u00f3gica abordada \u00e9 uma realidade pr\u00f3xima para notebooks, pc desktop e outros computadores de placa \u00fanica incluindo similaridade aos smartphones.<\/p>

\u00a0<\/p>

Para voc\u00ea que chegou pela primeira vez por aqui, sugiro que antes de navegar por esse post, links e principalmente assistir a todo o v\u00eddeo, veja antecipadamente os posts anteriores na sequ\u00eancia: “Pi OS Bullseye VPU: Youtube Acelerado? NetFlix, Disney+, HBOMax, Prime V\u00eddeo, rodaram? E Xbox Cloud?<\/a>” e “Raspberry Pi 4 N\u00c3O SERVE pra v\u00eddeos? Performance ruim? Veja isso! | GPU VideoCore P1 TimeLine<\/a>“<\/div>
