Sony mxf file fails to decode

[Carl Eugen Hoyos]

A user provided a mxf file from a Sony PXW-X180. It is supposed to contain audio, FFmpeg only decodes video but showing many errors. The decoding speed is said to be wrong.

Some quick analysis:

$ mxfdump sonyx180-1080-i50.MXF 
Dump an MXF file using MXFLib
- using dictionary "dict.xml"
ERROR: Cannot find valid key in first 65536 bytes of file "sonyx180-1080-i50.MXF"
sonyx180-1080-i50.MXF: Success

mxfdump doesn't seem to think it's an MXF file. Let's have a quick look with a hex editor:

0000 0000: 06 0E 2B 34 02 05 01 01  0D 01 03 01 04 01 01 00  ..+4.... ........
0000 0010: 83 00 00 39 5E 04 00 00  00 00 00 06 0E 2B 34 04  ...9^... .....+4.
0000 0020: 01 01 03 0D 01 03 01 02  7F 01 00 00 00 00 00 00  ........ ........
0000 0030: 00 00 00 00 00 00 00 00  00 00 00 00 81 06 31 21  ........ ......1!

Looks like there's two ULs here. There first one (at 0000 0000) seems to be an UMID, while the second one (at 0000 001B) is "MXF-GC Generic Essence Multiple Mappings". In other words, this is just an SMPTE generic essence container. There's no header, footer or index to help demux the file and it is not MXF. Indeed, ffmpeg considers it raw H.264, not MXF.

I suggest working out the format for yourself, then writing a simple little tool to split it up into raw video and audio.
