Encontrei uma explicação no formato proprietário aqui com um pequeno software para converter em mp4. Se puder ajudar
Comprei recentemente uma câmera IP da Luowice, modelo LWS-R8-2MP . A câmera fornece uma função na qual um vídeo é enviado para um servidor FTP quando um movimento é detectado. A câmera envia arquivos .264 . Meu plano é acionar um script quando um arquivo é carregado, o que converte o arquivo em .mp4 e o entrega por meio de um serviço de mensagens instantâneas. No entanto, não consigo converter o arquivo, pois ele parece ser um formato incomum ou proprietário. Eu tentei a solução mencionada aqui mas quando eu corro
ffmpeg -framerate 24 -i A180126_222057_222111.264 -c copy output.mp4
Eu recebo a seguinte saída de erro (isso é no macOS, mas o sistema de destino é o Linux):

Entrei em contato com o suporte do Luowice, mas eles só fornecem um aplicativo do Windows no site de download . convertendo os arquivos. Além disso, eles não explicaram o que há de tão especial em seu formato de arquivo. Estou procurando uma solução que funcione no Linux.
Alguém conseguiu converter arquivos .264 fornecidos por este modelo de câmera? É possível fazer o download de um arquivo de amostra aqui .
Atualização:
Entrei em contato com o suporte da Luowice e eles dizem que os arquivos .264 foram adicionalmente "compactados" para economizar espaço de armazenamento no cartão SD da câmera. Infelizmente eles não podem explicar como eles compactam os arquivos devido à "política corporativa".
Atualização 2:
Eu compilei o aplicativo C do artigo mencionado pelo Alain.fr e deixei que ele fosse executado sobre o arquivo de amostra. Ele gera um arquivo .mp4 . Infelizmente este arquivo ainda não pode ser reproduzido pelo VLC mas quando eu executo
ffmpeg -framerate 25 -i A180126_222057_222111.mp4 -c copy output.mp4
no arquivo produzido pelo aplicativo conversor, finalmente um vídeo reproduzível é produzido:)
Conclusão:
Em vez de uma compressão adicional, como alegado por Luowice, na verdade, algum lixo é adicionado ao fluxo H.264, que precisa ser removido.
Atualização 3:
Com base no aplicativo do conversor de Ralph Spitzner , que está escrito em C, criei um porta Node.js desde que meu aplicativo está escrito em Node.js;)
Encontrei uma explicação no formato proprietário aqui com um pequeno software para converter em mp4. Se puder ajudar
