[FFmpeg-user] Error when reading file as stream

[adam smith]

Hi you lovely people,

I have another question that I cannot find a resolution for, so I am hoping somebody can shed a little light on the subject.
When passing the source as a file into ffmpeg from regular storage, my ffmpeg commands are working correctly and I am happy with the output.
When passing the same source to ffmpeg as a stream, through pipe; I am getting errors. This is not for all files, eg mxf files containing DV50, XDCAMHD422 etc have not shown any issue, neither do many mp4 files.
All files are probed before the transcode and all come back as probe score 100.

The error I get complains about…
pipe:: Invalid data found when processing input
Cannot determine format of input stream 0:0 after EOF

This is the whole command and output…

Error marking filters as finished
Conversion failed!

I did try adding  ffmpeg -y -analyzeduration 100 -probesize 10000000 -i -  -filter_complex
But the same error occurred.

This is probably something to do with the fact that I am streaming the input, but I am not sure how to resolve it.
Any ideas will be warmly received

Thanks in advance
Adam
