Eu estava tentando converter um vídeo H264 para a resolução do iPod para poder assistir no meu Palm Pre. Acontece que enquanto o vídeo é convertido muito bem, a faixa de áudio parece ser dramaticamente desacelerada. Eu testei isso com 0.9.3 e svn2907 com resultados semelhantes.
Olhando em volta, parece que, embora existam relatórios semelhantes, não houve resoluções. FWIW, isso é no Snow Leopard executando 10.6.1.
A saída é a seguinte:
