Eu tenho um arquivo de vídeo mkv que contém o seguinte conteúdo:
> mkvmerge --identify original.mkv
File 'original.mkv': container: Matroska
Track ID 0: video (V_MPEGH/ISO/HEVC)
Track ID 1: audio (AAC)
Tags for track ID 0: 7 entries
Tags for track ID 1: 7 entries
Mas uma conversão 'padrão' usando avconv
não funciona (ubuntu 14.04), nem uma sugestão que eu achei em outro lugar (veja abaixo, e abaixo disso ...). O arquivo original não pode ser reproduzido por mplayer
nem quando reproduzido a partir de um disco rígido conectado a uma TV.
Como resolver esses problemas para converter o arquivo em um formato mais "normal / padrão", para que ele possa ser reproduzido por mplayer
e na TV?
