There was a problem hiding this comment.
Nite: closeAVIO() for consistency.

Failed to open input bufferaren't resolved as they were visible in https://github.com/pytorch/torchcodec/actions/runs/16238309871/job/45851804069?pr=757.So #724 is still a problem, and #755 wasn't a proper fix.
I hope this one is the one. It does 2 things:
avio_close()at the end ofencode(). Not just when the encoder is destructed. That makes sense.avio_flush(), which was potentially needed. I'm not entirely sure, but it's probably needed. Or at least it's fairly clear that callingavio_close()isn't enough anyway, because we are seeing the error not just when relying on FFmpeg's default avio object, but also when usingto_tensor(): https://github.com/pytorch/torchcodec/actions/runs/16238309871/job/45851804069?pr=757.
