Hardsubbing arquivos MKV que usam legendas .ass e fontes incorporadas

Question

Esta questão pertence apenas ao Linux e FreeBSD.

Eu tenho vários soft mbed arquivos anime mkv que eu preciso para hardsub. todos eles estão usando legendas .ass com fontes incorporadas. por exemplo mkvinfo em um deles me dá:

como você pode ver, existem muitas fontes incorporadas que são usadas neste mkv. Eu gastei 8 horas até agora tentando descobrir como fazer com que o mencoder codifique corretamente este arquivo para um avi que tenha as fontes incorporadas usadas no fluxo de vídeo. Mesmo que eu tenha extraído as fontes usando mkvextract, copiei-as para o meu diretório ~ / .fonts, e fc-cache -v ~ / .fonts para fontconfig, o melhor que posso obter é que o mencoder crie um arquivo usando a sub fonte default do mencoder .

Eu sei que deve haver uma maneira de fazer isso.

Eu preferiria uma resposta que usasse apenas ferramentas cli. Também prefiro evitar o avidemux como a praga, uma vez que ele gosta de travar ao lidar com subs .ass [apesar de qualquer sugestão ser bem-vinda].

    

Answer 1

Estou surpreso que você não tenha tentado o VirtualDub, que seria a alternativa mais strong. Funciona bem sob o vinho.

    

Answer 2

Você pode usar ffmpeg para anexar arquivos a um arquivo mkv. Um exemplo do manual do ffmpeg:

ffmpeg -i INPUT -attach DejaVuSans.ttf -metadata:s:2 mimetype=application/x-truetype-font out.mkv

IMO, ffmpeg (atualmente estou na versão 2.0.1 no FreeBSD de /usr/ports/multimedia/ffmpeg2/ ) é um bom substituto para o mencoder.
