Estou usando este comando para converter vídeos de M4V e AVI para FLV:
ffmpeg -i 'video_1355440448.m4v' -s '640x360' -ab '64k' -ar '44100' -q:v '1' -f 'flv' -y video_1355440448.flv
Eu tenho dois servidores:
- um servidor com a versão FFmpeg N-48249-g5079568, onde os vídeos funcionam bem.
- outro servidor com a versão FFmpeg N-48332-gfe5a2fc, onde os vídeos não estão funcionando bem.
Não há erros nos dois servidores e ambos os servidores convertem vídeos do mesmo tamanho. Se eu clicar para reproduzir este vídeo, ele faz uma pausa para o armazenamento em buffer e inicia 30 segundos ou mais depois.
Um servidor mostra qual parte está carregada com uma linha preta, mas o outro servidor não mostra isso.
Eu encontrei algo
