O VLC não acha que o arquivo contenha algo que possa ser reproduzido.

Como muru mencionado , vlc lhe disse: 

[00007f6924c01808] ps demux warning: garbage at input, trying to resync...

Nenhum dos resultados anteriores ou subsequentes foi particularmente encorajador ou sugeriu que você também tivesse um arquivo de vídeo real em funcionamento. O comando file geralmente parece apenas no começo de um arquivo para adivinhar seu tipo, e vlc foi capaz de tentar reproduzir o arquivo, mas não foi possível encontrar nada nele que pudesse ser reproduzido, nem mesmo qualquer coisa que parecesse como poderia ser reproduzido se você tivesse mais codecs instalados.

A parte "tentando ressincronizar" pode ter levado a melhores resultados se o problema fosse que o arquivo não estava sendo lido corretamente, mas não foi.

Parece que não é um arquivo AVI, em vez de precisar de codecs.

Antes de concluir que os dados que recebeu foram lixo, vlc mostrou mensagens como esta: 

[00007f6924c01598] avi stream warning: unknown chunk: �Qw! (not loaded)

Então, como Charles Green mencionou , te disse: 

[00007f6924c01808] avi demux error: invalid file: cannot find hdrl or movi chunks

Se este fosse um arquivo AVI real e o problema fosse apenas que você precisava de codecs, o VLC ainda poderia ter encontrado os dados hdrl e movi . Ele teria então falhado mais tarde, quando na verdade tentou reproduzir o arquivo. Você pode ter áudio sem vídeo, vídeo sem áudio ou até mesmo nenhum, mas isso teria acontecido quando ele tentasse interpretar os dados do movi no arquivo.

A Biblioteca do Congresso dos Estados Unidos explica o que hdrl e movi são todos sobre :

% bl0ck_qu0te%

Em vez de não conseguir decodificar dados de vídeo ou áudio no arquivo, o VLC nem encontrou metadados para informar onde estavam esses dados. Portanto, este arquivo era (a) nunca um arquivo AVI para começar, ou (b) corrompido. Se você obteve o arquivo via BitTorrent, geralmente é muito bom em evitar erros de transmissão (porque o hash de cada peça é verificado), então provavelmente ele foi corrompido antes de ser baixado, ou nunca foi um arquivo AVI real.

Outras possibilidades

Tecnicamente existem algumas outras possibilidades. Se você tiver motivos para pensar que o arquivo era bom, sugiro que seja:

  • Corrompido, embora você tenha usado um protocolo (BitTorrent) que geralmente impede a corrupção. A maioria dos programas BitTorrent tem um recurso de "force revise" que permite verificar que todas as peças recebidas estão com hash corretamente.
  • Um arquivo em que você precisava de codecs para que também foi chamado incorretamente de .avi quando na verdade era um tipo de arquivo de contêiner diferente. Isso ainda seria improvável, porque quando você olhou para o topo do arquivo (que o comando file olhou) ele ainda parecia ser um AVI.
  • Produzido por um programa destinado a produzir um arquivo AVI real, mas que apresentava erros sérios que faziam com que o formato estivesse errado, mas reproduzível com alguns outros jogadores que toleraram o formato errado (talvez devido bugs próprios). Acho que essa é a possibilidade menos provável, embora você possa tentar abrir o arquivo em um editor de vídeo como OpenShot como sugere Ravena .

Neste caso, você tem uma heurística poderosa para dar suporte à explicação de que o arquivo foi deliberadamente falso: veio com um arquivo executável (para o Windows) que dizia ser um instalador para codecs o arquivo necessário, que era acompanhado por nenhuma documentação, e múltiplos % bl0ck_qu0te%

Sim, essa é a explicação mais provável.
