In the ml archive I found an initial report on an early version of Baptiste's patch that caused exactly the same error message: ​https://www.mail-archive.com/ffmpeg-devel@ffmpeg.org/msg83824.html

Maybe it is related to this patch but that is just a rather uneducated guess.

ffmpeg version git-2019-04-30-5650668a1b remuxes it without problems.

[Syed Andaleeb Roomy]

It would be really nice to get this fixed since remuxing of P2 MXF is a major use case in one of our projects. Wish I could contribute in some way but unfortunately I do not seem to have the depth of format knowledge required for this particular fix, nor the access to the correct specs. Could anyone help here?
