O assunto está correto; -)
Meu problema é este: eu tenho um conjunto de arquivos MP4; todos eles jogam com vlc na minha caixa Ubuntu. Mas quando copiá-los para o USB; e quero tocá-los na minha TV ... algum trabalho; outros não fazem. O televisor é um Grundig, 28 VLE 5500WG. Não há mensagem de erro específica; apenas algo como "formato de arquivo desconhecido".

Eu percebi uma maneira que funciona (não tenho certeza se é ideal). Correndo
ffmpeg -i broken.mp4 -pix_fmt yuv420p -crf 18 good.mp4
Cria um MP4 que é um pouco maior (provavelmente minimamente pior em termos de qualidade) ... e isso funciona no meu aparelho de TV.
(mas ainda estou procurando outras respostas, se houver alguma)
Use Super Encoder / Copiar vídeo / áudio para mp4 Apenas tentei no arquivo mp4 com tag FOV no nome do arquivo. Ocelot estúpido é o problema. Agora toca na TV e no Blu Ray Player // ambos da Panasonic. Boa sorte
