rw_timeout trouble

Bouke / VideoToolShed
Hi all,
Strange issue:
Trying to transcode MXF ‘while in the making’ with the rw_timeout option.
It works on my end using Adobe Media Encoder for the MXF, but if Avid MC (on another computer that I don’t control) generates the MXF,
the first video frame gets doubled, and a more than expected by the video frame doubled audio offset.

Below is the FFmpeg command (not the ‘real’ command, I use Python to fire FFmpeg, and that takes care of the quoting / escaping stuff, the line is a rip off from the list I send…),
and the (JSON) FFprobe output I use to generate the command line.

Clues?
Thx,

Bouke

Shouldn't you use the -follow option as well?

Could you clarify this?

What is this magic with the -f lavfi - anullsrc=... ? I'd definitely try
first without it and the filters. Also you may try using -seekable 0
maybe it makes a difference about how the input mxf is read.
