Probable malformed index table of mxf files #157

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Encode any hd video (like hdcamsr35) into xdcamhd422
2. try to import xdcamhd422 file in latest open source editing software 
Lightworks 11.1.1
3. Crash of importer

What is the expected output? What do you see instead?
According to the editor:
The crash importing this file into Lightworks is caused by a malformed 
 index table segment within the file itself, our reader fails when 
 attempting to calculate the file length. The problem in the application 
 generating the file (FFMBC) is probably that it knows it needs to fill 
 the index table to the KAG size, detects that there is not enough room 
 left to accommodate the fill UL and size and therefore pads to the next 
 KAG boundary, but fails to reflect this in the index table header.

What version of the product are you using? On what operating system?
Latest Windows7 64 bits rc8

Please provide any additional information below:

- Full commandline run (with -v 3) and everything the program printed
without the repeating parts.
ffmbc -i input.mxf -vf "scale=1920:1080" -target xdcamhd422 output.mxf 

Seen for any xdcamhd422 file generated by ffmbc.

I validated files using IRT MXF Analyzer and no errors were reported.
I will close this issue unless a file is supplied.

Something is most likely wrong with the windows compiled version
