Estou tentando converter uma sequência de exrs gerada por uma renderização do Maya em um filme de quicktime. Estou executando o ffmpeg no Windows 7 (64 bits). No entanto, meu quicktime está saindo preto.

Acho que o problema tem algo a ver com o canal ZBack nos exrs:
[exr @ 000000000037f680] Unsupported channel ZBack.
[exr @ 000000000037f680] decode_block() failed.
Eu tentei a conversão com uma versão posterior do ffmpeg (20170921 - 183fd30), mas acabei com uma mensagem de erro totalmente diferente:
[exr @ 000000000032b120] flags 8 is not implemented. Update your FFmpeg version
to the newest one from Git. If the problem still occurs, it means that your file
has a feature which has not been implemented.

Consider increasing the value for the 'analyzeduration' and 'probesize' options
Alguma dica de como resolver isso?
===== Atualização =====
Estranho. Eu executei uma versão atualizada do ffmpeg em alguns arquivos de teste (como fiz anteriormente) e recebi algumas novas mensagens de erro.
