Answer 5

Olá flashed!

De uma forma direta podemos ver os codecs como uma exigência pra reprodução de uma determinada extensão de mídia (um pacote de atualizações).

O seu reprodutor de mídia precisa do codec, não a sua aplicação.

Obs: Analise todo o conteúdo sugerido pelos amigos acima, nesta thread você tem tudo o que precisa pra sua aplicação funcionar.

Answer 6

boas

sim são boas respostas :) Obrigado a todos

Estou a tentar converter o projecto que o William falou de c# para vb.net e não está a ser facil :/

Estou a ponderar fazer conforme este exemplo http://www.youtube.com/watch?v=5v5Iq5gFvf0 e incorporar os codecs no próprio projecto vb. O que acham?

é que o objectivo e ver pequenos videos, não é preciso grandes coisas ;)

Se sim, como e quais codecs adiciono no projecto?

Se for como as dll´s é na boa eu sei adicionar ;)

Obrigado a todos
