[issue1470] Can't open MXF file from BBC ingex recorder - could not resolve material track sequence strong ref

[Philip de Nier]

Philip de Nier <philip.den...@rd.bbc.co.uk> added the comment:

Patch #5:

Requires patch #4.

Add support for 10-bit v210 uncompressed picture. Also added the 8-bit picture
essence coding label from s377m-2009, in addition to the 10-bit label, which
signals the uyvy 4:2:2 format.
