Nenhum vídeo com HTML 5 player no YouTube sob Iceweasel

Question

Hoje, percebi que não recebo nenhum vídeo (o áudio está lá) ao assistir a um vídeo do YouTube usando o player HTML 5 (ativado no link ).

Se eu usar o Flash Player, tudo funciona corretamente, mas eu prefiro evitar isso.

O que eu tenho do gstreamer instalado é:

ii  gstreamer0.10-alsa:amd64                     0.10.36-1.1                       amd64        GStreamer plugin for ALSA

Parece que estou perdendo um codec, mas não sei qual. Eu estou usando o Debian "testing", Iceweasel 26.0. O que fazer?

    

Answer 1

Você precisa instalar o pacote gstreamer0.10-ffmpeg .

Depois, para ver se funciona, vá para link e veja se há um visto verde ao lado de H.264 .

[edit] Em versões recentes do Debian (> = 8.0) você precisa do gstreamer1.0-libav
